An Update on the Wellsite Information Transfer
Standard Markup Language (WITSML)

• Alan Doniger, POSC April 2005

WITSML WWW.WITSML.ORG Wellsite Information
Transfer Standard Markup Language The
right-time seamless flow of well-site data
between operators and service companies to speed
and enhance decision-making A New Open
Information Transfer Standard for the Oilfield
3

• WITSML started as a collaborative effort to
  update the widely used WITS standard for moving
  drilling data between rig and office based
  computer systems
• WITSML is designed for the standards of today's
  always on Internet environment while still
  accommodating those rigs not yet Wired
• WITSML is published and available to all to
  implement
• Real world use of WITSML is happening NOW
• The scope of practical usage is being extended
  based on practical experience and pragmatic needs

BP Vision

• Automation of many manual processes in current
  Drilling Data workflows
• Contractors (Service and Drilling) automatically
  push data into our corporate data stores
• Partners can automatically pull data (Not images)
  for morning reports into their data stores
• Operators can push statutory reporting data for
  statutory reports
• Contractors can share data with one another at
  the rigsite
• A single standard to make the vision possible,
  reducing industry costs

Drilling Issues

• Maximize well productivity
• Minimise formation damage
• Avoid pressure problems
• Steer the drill bit
• Find and stay within hydrocarbon zone
• Requires a combination of different measurements
  from different companies and collaboration
  between different disciplines (Drilling, Geology,
  Reservoir)

The POSC WITSML Special Interest Group (SIG)

• The WITSML SIG is the formal user community for
  the WITSML standards.
• Membership is open to all (POSC members and
  non-member alike)
• Membership grew in 04 from 17 to 31 now 35
• The SIG recognizes requirements and needs
• The SIG is the first line of review of new and
  updated specifications
• The SIG helps promote vendor take-up and operator
  deployment

9
WITSML SIG

• Area of Interest
• the definition, movement, and storage of drilling
  data, information, and knowledge,
• especially the right time seamless flow of well
  site data between operators and service companies
  to speed and enhance decision-making.
• This group is essentially a cross-vendor,
  cross-product line user community for drilling
  applications and data storage products and
  services.
• Players
• operators, service and software providers,
  government agencies, consultancies, and POSC.

Extending WITSML

• WITSMLs original mandate for wellsite to
  operator (contextual and real-time) data
  transfers can be reused for many EP data
  exchange work flows
• to partners, to labs, and more
• All using a common architecture, common
  terminology, maximal commercial product and
  service incentive, etc.

Why has the WITSML initiative been
successful?Some lessons learned / best practices

• The Right Initial Players - clear focus
• BP Statoil with Baker, Halliburton,
  Schlumberger, and NPSi
• Strong Commitment
• Initial funding by oil companies Oil service
  companies remain engaged after initial delivery
• Effective Processes
• Practical, incremental approach
• Clear focus on target outcomes - through
  implementation
• Frequent communications - steering technical
  teams
• Choice of Technologies
• XML, SOAP
• Comprehensive Output and Documentation
• XML Schemas Server API sample implementation
• Openness / Evolution
• Public seminars and presentations
• Transfer to POSC in early 03 -- commercially
  neutral custody, publication, promotion and
  evolution

32
What we must do in the future?

• Maintain enthusiasm for the vision
• Continue to involve interested and committed,
  knowledgeable people
• Address use cases that add real (quantifiable to
  management) value
• Keep the spirit of trust and cooperation between
  competitors
• Have oil companies supply chain management
  provide contractual re-enforcement
• Increase cooperation among different domains to
  minimize duplication working with similar types
  of data and to maximize re-use of work already
  done

WITSML SIG Membership Tops 30 Organizations

• The number of service and operator organizations
  making use of the WITSML Standards continue to
  grow. More have joined as SIG members.
• The SIG began 04 with 17 members and ends 05
  with 31 members.
• Recent additions to the SIG include Total, US
  Department of the Interior, HRH Geological
  Services, Smith Technologies, IFP, Interaction,
  US Synthetic, Knowledge Systems, Aspentech.
• And Roxar, Key Energy Services, and M/D Totco

43
Mud Log Sub-Teams Work Evolves Into Formal
Change Requests

• In Sep. 03, it was agreed to review and enhance
  the mud log data specifications of WITSML.
• A sub-team, led by ExxonMobil, worked throughout
  04 leading to a set of change requests
  integrated into WITSML Version 1.3.
• ExxonMobil is leading a pilot project to test the
  mud logging work flow. Other organizations are
  invited to joint his pilot test or to organize
  tests of their own.

44
Version 1.3 On-Track for Year-End Release

• The previous release of the WITSML Standards was
  made in early 03 as Version 1.2. In the fall of
  03, we set a target to release an enhancement
  version by year-end 04.
• A list of issues was managed throughout the year.
  Individual issues were resolved as
  clarifications, minor fixes, or larger issues. By
  the fall WITSML meetings in Nov. 04, almost all
  pending issues were resolved.
• The final review period for the SIG and the
  public will close at the end of Jan. 05.
• After post-review issue resolution, Version 1.3
  was finalized and published in mid-March 05.

45
Well Path and Well Log Data Transfer Standards

• In early 04, POSC stated the policy of
  integrating all data exchange standards in an
  extended family of WITSML Standards.
• One area of enhancement provides support for
  wellbore paths and trajectories planned and
  actual measurements and calculated results.
• A second area of enhancement extends support for
  well log data to include wireline as well as LWD.

46
Use Case and Requirements Team Looks to the Future

• At the WITSML meetings in Paris in Nov. 04, the
  following were identified as candidate future
  subjects.
• Daily Drilling Reporting (BP, ChevronTexaco, and
  Hydro expressed interest)
• Completions and Well Mechanical (ChevronTexaco
  has used a draft version of this Statoil,
  ExxonMobil, and Hydro are interested)
• HSE Reporting
• Operational Data Reporting to ERP Systems
• Distributed Temperature Surveys (underway as an
  IntOPS SIG effort)
• Well Services has been proposed and approved for
  consideration in 05

47
Product Certification Program Will Start in
Early 05

• A Certification Program for POSC Standards is
  being beta-tested for WITSML enabled products.
  This is a self-certifying program, in which
  product vendors fill out a form indicating the
  nature of their products use of WITSML.
• Products in the program may use a special logo
  and the phrase, POSC WITSML Certified Product
  in literature and on packaging.
• A related program allows oil companies to be
  designated as Registered Users of the WITSML
  Standard.
