The Oil and Gas Industry Todaypaper
The United States and the world economy have a huge thirst for hydrocarbons
which will persist and grow for many more years into the future. Security
of supply issues will require new reserves to be discovered and placed
on-stream. Canadian investment will be made by junior companies exploiting
the gas potential in smaller pools while multi-national corporations
will focus upon high impact sustainable reserves such as the Foothills
and the Frontiers. Natural gas is fast becoming a worldly traded commodity
as the United States thirst for sustainable supply continues. Technological
innovation and access to information continues to elevate local economies
to the global stage. Data standards are an important component to facilitating
the global economy.
Supply and Demand
The world community consumes approximately 78 MMB/D of oil. The United
States (US) consumes approximately 20 MMB/D or 25% of world supply while
producing only 5.77MMB/D of production. This leaves the American economy
heavily dependent upon foreign supplies to fuel their guzzling economy.
Labour unrest in Venezuela earlier in the year caused a supply shortfall
which was absorbed by OPEC nations. Covering this shortfall, left many
OPEC nations maxed out. Saudi Arabia increased production from 7.8 to
9.2 MMB/D. Fear of sabotage during the Iraqi invasion led to fears of
a further supply shortfall. Subsequently, Venezuela has been able to
increase production to half of what their supply use to be. Ongoing
pipeline sabotage in Iraq has mitigated Venezuela’s gains. Unrest
in Nigeria continues to cause some minor world supply disruptions.
World consumption is increasing at a rate of approximately 2 MMB/D.
Iraq’s reserves are significant and are estimated to be 200 billion
barrels. Canadian Oilsand reserves are estimated to be 315 billion barrels
with 175 billion barrels recoverable. Canada’s production is anticipated
to increase from 2.3 MMB/D to 3.5 MMB/D by 2010 largely due to investment
in heavy oil projects.
Gas Supply and Demand
North America consumes approximately 33 percent of the world’s
gas supply from approximately 5 percent of the world’s reserve.
The United States consumes 50 BCF/D of natural gas. Canada produces
17.4 BCF/D and is the third largest gas producer in the world and the
second largest exporter of natural gas. Gas well production from the
Western Canadian Sedimentary Basin (WCSB) is declining at rates of 25
percent per year. Production replacement in 2002 was 93 percent of production.
A total of 3.5 BCF/D of new production must be found to hold WCSB production
flat. Exploration for natural gas is increasing with a focus upon sustainable
production. Higher commodity prices have permitted smaller reserves
to be tied-in. In Canada, Royalty Trusts continue their popularity.
Dividend distributions however continue to export value out of the sector,
taking with it investment capital for future exploration. Large multi-national
corporations are searching for high impact reserves with sustainable
The United States is interested in seeing the MacKenzie Valley Pipeline
and / or the Alaskan pipeline built to offset future supply concerns.
Exploration in the Arctic National Wildlife Reserve ( ANWR ) is currently
blocked by the US senate because of environmental concerns. The United
States is aggressively building Liquified Natural Gas ( LNG ) plants
to cover for future North American supply shortfalls. As a result, natural
gas is fast becoming a world traded commodity.
Resource Accessibility
Infrastructure, competing land uses, environmental concerns and community
interests may limit access to Canadian reserves by 10-20 percent. Sustainable
high impact reserves require longer cycle times and larger capital requirements.
Native land claims has delayed land nominations in the North West Territories
and the Yukon. A moratorium on the West Coast has denied access to exploration
opportunities. A fine balance must be achieved between energy supply,
resource access, standards of living, local community interests, environmental
groups and other land uses.
Technology
’s
technological capabilities. An emphasis on the accuracy and completeness
of databases will make this technology more valuable as the historical
quality of information is improved. Global data standards need to be
created and indoctrinated to enable individuals to further enhance productivity
in a global economy.
Salsa With Your Chips? paper
Janice’s presentation gave a light hearted comparison of performing
an information system project in North America vs. South America. The
approach is to take the practical, business aspects of the work and
compare the perception, acceptance and practice for planning, resourcing,
supporting and implementing the multi-faceted attributes of IMS development
in two different cultures. The nuances of general business practice,
language and work environment can lead to some unique challenges but
is there a viable difference - or is it just the same destination with
a different passage?
The Future of XML Data Exchange: How the PPDM
A&D Project Creates Value for the O&G Industrypaper
This presentation will focus on how value can be created for the O&G
Industry through collaboration on XML (eXtensible Markup Language) standards.
The PPDM project to XML-enable Acquisition & Divestment Data Exchange
will provide the foundation for a vast array of innovative developments
that will make A&D business processes more efficient and effective.
This presentation will outline how this initiative was facilitated by
PTAC (Petroleum Technology Alliance of Canada) and PPDM (Public Petroleum
Data Model Association) and how new initiatives could be launched in
the future for the benefit of the O&G Industry.
An XML-Based Exchange Format for
Depth-Registered Well Log Imagespaper
As the popularity of depth-registered well log images has risen over
the last few years, so has the need to develop a common format for data
exchange of these images. While most well log images are delivered in
a standard TIFF format, it’s an accompanying file (the registration
file) that makes an image “depth-registered.” For these
registration files, there is currently no standard. An XML based exchange
format for depth-registration files being developed by IHS Energy Log
Services has been designed to provide such a standard.
There are a growing number of Geoscience Interpretation Software packages
on the market today, each with their own uniquely formatted registration
file. The content of these unique files can vary significantly. Users
who are maintaining more than one application or want to change applications
are faced with managing a multitude of registration files for each TIFF
image.
By leveraging the power of XML, this new format can be easily translated
into existing, proprietary depth-registration formats. Therefore, software
providers can retain their existing data formats as necessary. An XML-based
format facilitates easy data exchange and loading into PPDM or other
database models.
This format provides a finer granularity for capturing detailed data
elements from within the well log or from alternate data sources. A
number of benefits are afforded by this approach: greater flexibility
while customizing views within cross-section applications; the ability
to extract key elements of the well log image; and a more robust dataset
for loading into a database.
PPDM Acquisition & Divestment Project Updatepaper
The PPDM Association proposes an initiative to develop a standard data
exchange format for acquisitions and divestments that satisfies the
technical and business requirements of E&P companies, service companies
and vendors. The standard would be based on XML technologies and would
build upon the results of other data exchange standards created by the
PPDM Association.
A&D processes necessitate the creation and repeated transfer of
data between sellers, brokers and buyers. Therefore, the importance
of maintaining data integrity and facilitating easy access to relevant
data items is crucial. A standardized format for A&D data would
decrease the costs associated with maintaining multiple file formats,
facilitate the exchange of data between companies, and ensure the validity
and integrity of the data during transactions. . The collective XML
Standards defined by PPDM will be referred to as the eXtensible Petroleum
Acquisition and Divestment Language or simply ‘XPADL’.
This Presentation is intended to provide a general update on the status
of the Acquisition & Divestment (A&D) Project at the PPDM Association.
It includes a review the industry business drivers behind this initiative
and outlines the scope of the project.
PPDM Technical Updatepaper
Business driven standards developments create opportunities to improve
E&P processes and procedures. Knowledge management has been much
in the forefront of industry attention lately, and for very good reason.
The information explosion of the last decade has escalated a crisis
that has only recently been reacted to. PPDM standards work to resolve
knowledge management issues in the areas of data storage (the relational
model), data exchange (XML schema), data use (spatial enabling) and
standardized content values (data content).
PPDM 3.7
PPDM version 3.7 beta 1 has been released for general member review
and comment. This model has expanded by over 40% through the combined
efforts of four work groups, who have added functionality to support
surface land operations, paleontology, reserves and well logs. Your
conference CD contains copies of the PPDM 3.7 beta 1 roadmaps and a
description of each module.
Plans are for a production release by the end of the year or early
in January 2004. Prior to this, a final review of all change requests
submitted by workgroups and members must be completed and additional
revisions made. Member discussion about changes is posted on workgroup
list servers; visit www.ppdm.org to subscribe to list servers.
XML Schema
Schema development has continued through the last fiscal year. As our
member expectations have expanded, the scope of expectations for schema
has grown. Original schemas were targeted for moving data around on
the Internet (data streaming). More recent developments have precipitated
the inclusion of data viewing and manipulation on the Internet. The
PPDM Association is using some schemas for internal purposes; this includes
the use of schema for PPDM data model documentation and the generation
of other deliverables.
Current XML projects include well headers, well directional surveys
and Acquisition and Divestment. Work in progress for each project may
be downloaded from the PPDM web site.
Spatial Enabling
Since 1999, the PPDM Association has worked collaboratively with industry
to develop mechanisms for spatially enabling PPDM information. Each
of the past three phases has added new capability; the results of each
phase have been successfully adopted by industry. The next phase targets
the development of a light weight data model that encompasses a summary
of all the key data types required in the G&G process.
Data Content
Two data categories have been added to PPDM this year. Geodetic information
was acquired from the EPSG (European Petroleum Survey Group). Unit of
measure information has been gathered from several sources, including
the IEEE, API and POSC. Both data categories will be published with
PPDM 3.7. Work in upcoming months will update the country codes list
and add seismic reference values to the data set.
Leveraging PPDM Through an Integration Framework
The PPDM data model delivers value to oil companies and software vendors
that use this data model to store and manage their key E&P data.
This paper discusses the added value of using a application integration
framework that allows users to access both PPDM , GeoFrame, OpenWorks,
Finder, and other databases through a consistent object interface and
allows multiple vendor applications to dynamically share data and user
interaction events. Example of cross-platform, cross-vendor workflows
will be shown that illustrate the potential advantages of “publishing”
PPDM data into such an integration framework.
Building and Maintaining a Spatially-enabled
PPDM Databasepaper
Lynx joined PPDM Association just over one year ago. A service company
with a longstanding tradition of using desktop GIS as a means of retrieving
and analysing exploration and production data, we were attracted to
the Association by its ongoing efforts to spatially-enable the PPDM
database model. A growing inventory of in-house data underlined the
need for a mature databasing strategy, and as committed ESRI users we
wanted a solution that would embrace the Geodatabase concept and allow
enterprise-wide deployment of GIS applications.
Broadly following the methodologies and results achieved by the PPDM
Spatial II workgroup, we set about implementing an Oracle 8i/SDE Database
that initially dealt with modeling well data. Whilst Spatial II Part
1 showed how linear referencing of well deviation measures could be
employed to model wells as 3D lines, our primary concern was to spatially-enable
the basic surface locations recorded in the PPDM 'WELLS' table, the
majority of our well data being 2-dimensional. A caveat of this is that
we wanted a database that did not rely on breakout tables but could
be dynamically maintained i.e. one that could be updated using Oracle
procedures and triggers.
Our next task was to spatially-enable our 2D seismic location data
using linear referencing. Again, we required dynamic maintenance of
the metadata in the PPDM tables and the seismic trace coordinates displayed
in the GIS.
The solution we have implemented for spatial enabling of well and 2D
seismic data uses SQL-scripted triggers and Oracle Spatial as the spatial
repository, and SDE to interface with client-side GIS. We will illustrate
our talk with case studies from the UK and/or Libya, and a demonstration
of some of the tools, techniques and procedures that we have devised
and put into everyday use for database upload, maintenance and GIS visualisation.
Units of Measure in PPDMpaper
A surprising variety of units of measure are in use today. In addition
to the International System of Units (SI), there are a variety of metric,
US, Imperial, and historical units of measure in use by industry.
We have collected standards from SI, IEEE, ASTM, API, POSC, EPSC, and
other sources, along with conversion factors for the most common unit
conversions. From the magical certainty that a Hogshead is half a Butt,
to the question of whether the bar will be deprecated (ANSI discourages
it, but API still shows it as current), there’s more to units
of measure than you might guess.
The PPDM database tables include the reference source for each unit,
so you can always go back to the horse’s mouth if you need to
know exactly how long a meter is these days, or why ANSI recommends
you measure radiation dosage in sieverts instead of rems.
Whether you’re converting cubits to furlongs, making sense of
the weather forecast, or switching to SI, you’ll want to know
why some people just can’t be satisfied with the conversion formulas
we grew up with.
Units don’t just have names – they’ve got shorthand
symbols. Which one you pick depends on whether you’ve got Greek
characters and superscripts available to you, and whether you want to
send the value to someone else using XML.
Our emphasis is on simplicity and usability.
Geodetic Data in PPDMpaper
Claude Williamson provides an update on changes to the PPDM Geodetic
Data Model that was suggested at last year's AGM.
PPDM Business Development Updatepaper
The PPDM Association 2003/2004 business plan reflects an improved strategy
in growth and growth tracking. The PPDM Association’s intent is
to implement steady, controlled growth tactics in global membership
and projects in E & P, then gradually expand to industries such
as coal bed methane, environment, pipeline, utilities, fisheries and
mining.
These new industries have common characteristics with work already
completed for the E & P industry. Expansion to other industries
leverages our existing model and knowledge without extensive increases
to the Association’s costs and manpower. As with the E & P
sector, these industries are affected by the Kyoto Accord and must be
able to manage, evaluate and report data in a standardized, cost effective
manner to various government bodies.
Over the next fiscal year, we will endeavor to increase our exposure
to the E & P industry, to branch out into downstream, health, safety
and environment, human resources and other E & P functions and to
increase the level of global awareness of PPDM. Finally, we will expose
PPDM standards to selected new industries.
Increased presence at conferences, seminars, professional organizations,
publications and luncheons will be key tools to penetrate new markets
and raise awareness of the PPDM Association. Many conferences and professional
organizations represent industries that are inter-related. Initially,
we will seek out opportunities that enable the best exposure for the
least time and cost.
Growth in the PPDM management team has allowed the Association to take
advantage of specialized skill sets in the areas of marketing, administration
and technical leadership. The PPDM Association will implement improved
processes and procedures that incorporate best practices for increased
revenue generation through our membership, project sponsorship and other
channels of revenue generation.
Well Log Data Management – A Fit-For-Purpose
Solutionpaper
Petrophysical Log data is a critical datatype for both the exploration
and production processes within the Oil & Gas business. It is used
by multiple disciplines within multiple workflows, it needs to be easily
accessible to all users and must be available to several different applications
in a variety of formats. It requires good management of meta data, standards
and must be available as an integrated dataset with other data types.
The solution created at Woodside was to create a system with a fully
automated data-flow, single point of entry and multi-platform accessibility
to the data. The web-based data-loading and data-retrieval tool provides
the logs in several formats and allows for meta-data capture at loading
time. Storing the data in PPDM provides a means of integration with
other datatypes and the ability to store the data in a variety of formats.
Users can then access this data with tools such as OpenWorks for interpretation,
Logic for QC & interpretation, dbMap and ArcGIS for mapping, and
Business Objects for reporting. The implementation has been successful
and "embraced" by the community, but there were challenges
along the way with satisfying all disciplines requirements, issues with
legacy data and technical problems in dealing with multiple file formats.
Four Reasons Why E&P’s Fear Poor
Data Qualitypaper
Ignoring poor data quality within any company is a risky decision.
Many managers and executives are unaware that they rely on information
that is fraught with invalid assumptions, is inconsistent and incomplete
and is based on data that is frankly wrong. Yet E&P executives,
managers and staff make critical decisions and base their professional
reputations on a fog of poor quality data. “If you don’t
know how good your data is then how can you trust it?”
Often there is an expectation that historical data quality issues have
little to no impact on the present; however, just because the data was
created in the past (and likely by someone else) does not erase the
operational, contractual, and regulatory risks associated with these
assets. There is a perception that if you deploy the “latest and
greatest” technology, data quality will magically improve. Finally,
E&P’s are often unable to articulate a business reason why
they should worry about the problem in the first place.
This presentation discusses how Exploration & Producing (E&P’s)
companies are starting to take the first step in reducing the risks
of poor data quality by evaluating and profiling their data. Hear what
data quality means and how it affects the top levels of management down
to those working with the information every day. Discover how new emerging
technologies focused on solving the data quality problem are leveraging
standards like PPDM to achieve higher levels of accurate information.
PPDM Supports Business Process Improvementpaper
An explosion in exploration and production data volumes is threatening
to overwhelm the improvements that many E&P companies have made
in improving their business processes and data management practices.
Exploding data volumes originate from the current forces that are driving
the upstream E&P industry today. These forces include:
- Asset Mix/Optimization
- Shareholder Return
- Oil & Gas Price
- Technology
- Workforce Demographics
- Globalization
- Environment
In this presentation, Yogi Schulz will describe successful approaches
to enhancing data management with PPDM to strengthen:
- Computing Infrastructure
- Software
- Business Process
- Data
These approaches will enable E&P companies to meet the challenges
posed by the forces that are driving the E&P industry and retain
the value that business process improvements have already delivered.
The Evolution of the Data Centre/Data Warehouse:
Digital Data and Beyondpaper
Brad reviews the Data Centre/ Data Warehouse from an historical perspective
and then presents the current situation. He examines the emerging trends
in hardware, software, networks, data, operating systems etc. in relation
to the data centre and explores some challenges for the future.
Tip of the Iceberg: data Management in Oil and
Gaspaper
Data management is a critical item for oil and gas companies. Data
volumes have been growing at a prodigious rate in the last decade. Various
solutions to manage the data volumes and the associated meta-data have
been developed in-house (by oil & gas companies) and as commercial
products by oil & gas vendors. Has the time come that a consistent
common data management methodology be developed by the oil & gas
industry for the oil & gas industry?
This talk will review the problems associated with storing, managing
and extracting information from the large data sets that are generated
within the oil & gas industry. Problems around data context and
content have made management of data a difficult and costly endeavor
for companies. The talk will then focus on the nomenclature in use today
and move to explore the development of standards in this area. The development
of industry standards are best done as a collaborative effort; such
as a PPDM work group. The author hopes that industry representatives
will participate in the formation of a data management work group later
in the week.
Spatial Project Updatepaper
GIS makes vast amounts of data available to users. This data is an
integral component of exploration for and production of hydrocarbons.
Oil companies, data vendors and application designers are using business
driven models such as PPDM to make this data available to their users.
Spatial E&P data is typically managed differently from traditional
attribute data. Spatial enabling PPDM allows spatial data and GIS specific
data to be integrated with existing data management processes creating
increased value for organizations. The PPDM Spatially enabling project
has completed three phases; implementation of the recommendations generated
has saved time and money while reducing cost and effort.
However, the complexity inherent in E&P data means that the presentation
of the data can become difficult, non-intuitive and frustrating. Users
feel overwhelmed by the volume and complexity of the data they must
sift through every day.
Fully enabling a corporate data model such as PPDM can be a large and
daunting undertaking that may not immediately return value in proportion
to the effort required, especially for small companies. Access to a
small spatially enabled data set that allows users to perform typical
spatial queries solves many problems.
Spatial IV will use PPDM and other existing Geodatabases to create
a simplified, denormalized data model that will focus on spatial data
and how to present summaries of data stored in PPDM to G&G (Geologic
and Geophysical) users who only require high level information. For
convenience, the expected data model has been referred to as PPDM Lite
or PSDM (Petroleum Spatial Data Model).
The data modeled will represent the business requirements of sponsor
companies. In some cases, summary data may be created for business areas
not in PPDM at present; these areas may be viewed as a starting point
for detailed modeling for full PPDM. In these cases, existing Geodatabase
standards may be canvassed to determine their applicability to the business
requirements.
Data Exchange Project Update paper
This Presentation is intended to provide a general update on the status
of the Data Exchange Project at the PPDM Association. It includes a
background on the concept and history of the project and examines the
role of XML Schema in the creation of data exchange standards.
The current phase of the Data Exchange Project focused on the development
of standardized XML transaction for Well Header and Well Directional
Survey data. The schemas were developed via cooperation and collaboration
with POSC. The strategy and methodology behind the development of the
XML Schema based on this collaboration is outlined. In addition, the
deliverables of the current phase of the project and how to obtain them
will be presented.
New Workgroupspaper
Data Management Workgroup
Member implementations of the PPDM data model have grown substantially
in past years. Increasingly, data managers have been looking for tools
and mechanisms that will help with the day to day business of handling
data, loading bulk datasets into PPDM, ensuring that appropriate audit
trails and archival processes are implemented and integrating multiple
databases.
The majority of PPDM work groups design data modules that handle business
data related to wells, biostratigraphy, land management and more. Each
of these work groups has recognized the importance of data management
and data base administration; this urgency has been communicated with
the PPDM Association with a recommendation to form a specialized work
group to address these issues.
The potential scope for a PPDM data management work group or project
could be enormous. While the final scope for the project will be set
during the kick off meetings, the following areas will be put forward
for consideration:
- Recommendations to the modeling committee have been deferred to
this workgroup
- Complete review of the meta model and its functions
- Review of the model for conformance to regulations such as Sarbanes-Oxley
and PIPEDA
- Development of best practices recommendations for data management
in PPDM
- Development of best practices recommendations for data base administration
in PPDM
Taxonomies and Meta Data Workgroup
Independent computing resources, such as desk top personal computers,
allow individuals to generate information at an unprecedented rate.
Each year, a person working at normal capacity can easily generate hundreds
or even thousands of documents with content ranging from administrative
to technical or interpretive.
Many of these documents are unstructured (as word files, acrobat files,
web pages etc) or semi-structured (spreadsheets, XML documents). If
unstructured or semi-structured documents are to be usable in the long
term, each document must be identified, classified, stored and managed
correctly.
Legislation and regulations promulgated by various governments set
out requirements for availability and accessibility of information,
particularly for publicly traded companies. Other legislation sets forth
requirements for ensuring the privacy of personal information. Balancing
these requirements can be complex and difficult. Fortunately, the prevalence
of these issues has inspired the formation of many standards committees
and work groups upon which PPDM can build.
The World Wide Web Consortium (W3C) recognized the importance of integrating
and searching structured data (databases), unstructured data and semi-structured
data early. The Dublin Core initiative (dublincore.org) in their own
words “is an open forum engaged in the development of interoperable
online metadata standards that support a broad range of purposes and
business models”.
The Web Ontology Language (OWL) initiative “is designed for use
by applications that need to process the content of information instead
of just presenting information to humans”. These functions are
intended to maximize user success in identifying and retrieving important
information using the World Wide Web. Further initiatives by Shell Expro,
Flare Consulting, PPDM, ESRI and POSC are working to tailor these capabilities
in forms suitable for the E&P Industry. Successful implementations
can substantially increase the value of information while reducing the
cost of managing it.
The work group will develop methods and schema that allow taxonomies
and Meta data to be handled in PPDM or data exchanges. Some work in
this area has been completed and made publicly available; the work done
by Shell and later adopted by POSC and vendors is a good example of
a catalogue system that specializes in well related information. Other
schema will be identified and considered.
A methodology to map the contents of taxonomies and Meta data schemes
and PPDM will be developed. A mapping between the contents of one or
more existing catalogues (a combination of taxonomy and Meta data) and
PPDM will considered as a test case.
New taxonomies and Meta data catalogues will not be developed through
this work group in the foreseeable future. This work will most likely
be undertaken by other standards bodies, vendors and implementers.
Well Operations Workgroup
Technological advances have allowed the E&P Industry to introduce
substantial improvements in creating, managing and analyzing data about
day to day well operations. In 1995, Canada started with the creation
of an electronic well tour sheet that is supported and endorsed by the
Canadian Association of Oilwell Drilling Contractors (www.caodc.ca/).
This format is used for electronic well tour reporting by the vast majority
of rigs operating in Canada today.
Other standards bodies, such as the Wellsite Information Transfer Standard
Markup Language group (www.witsml.org) have created XML based transfer
standards for real time operational data that are still being developed.
Over the last several years, electronic methods for creating and sharing
well tour information have evolved become widely accepted. These data
exchange mechanisms have allowed companies to receive well site information
in a very timely fashion. Unfortunately, however, this information is
often managed in proprietary applications and systems, or as a collection
of files. This does not promote the open sharing and use of well operations
data.
The PPDM Association proposes a work group to collaborate with Industry
in evolving the PPDM relational model to handle well operations information.
Business needs exist in several well operations domains. The potential
scope for a PPDM well operations work group or project could be enormous.
We will address the requirements in phases, starting with a quick win
such as the well tour reports.
Phase I will provide a mapping between PPDM 3.7 and the CAODC well
tour report (and other regional formats if provided and required by
the work group). PPDM 3.8 will be extended to provide full support for
these data formats.
Phase II will identify additional gaps in the information required
by the E&P Industry to appropriately track and analyze well operations.
Later phases to incorporate this missing functionality will be set
up as needed, based on the results of this work group. This functionality
may eventually include full support for real time operational data,
depending on the requirements of the work group and PPDM Membership.
Other Workgroup Opportunities
- Royalties
- Well core analysis
- XML schema and model enhancement
- Financial capability
- Geochemistry
- Well log interpretation
- Heavy Oil
- Coal Bed methane
Collaborative model review
Professional associations, such as CAPLA, ARMA, PODS, PADA, EPSG have
been granted contributing memberships in the PPDM Association to further
opportunities to develop PPDM standards that address current business
requirements and opportunities.
