Why WITSML?

• Adoption of WITSML is driven by
• Ease of data sharing
• Real-time capabilities (internal and marketplace)
• Increase in use of real-time collaboration and
  monitoring centers
• Portability of WITSML compliant products
  services
• And so
• WITSML is an enabler
• Especially in a multi-vendor environment
• Improves operators and service companys ability
  to distribute information to internal and
  external experts, services and tools without
  boundaries

7
What is WITSML?

• WITSML is a drilling communications standard
  which defines the transfer of real time
  information between different systems in a
  consistent way leading to more effective data
  integration.
• WITSML facilitates real time decision making
  which should have a direct impact on drilling
  performance.
• WITSML is a collaborative effort.
• WITSML is open to all to implement

Evolution

WITSML Evolution

• Different service companies monitoring the same
  well with incompatible software and hardware
  platforms
• WITS in the 1980s
• Point to point serial data transfer
• Binary and ASCII data formats
• Incomplete data set and out of date by late 1990s
• WITSML started in 2000
• Evolved from Statoil DART project
• Discussions with BP Statoil, Baker Hughes,
  Halliburton Schlumberger led to WITSML

Product Certification Program

• Initially self certification
• Product certification programme now available
• Server test suite 1
• Trial run at November 2008 WITSML SIG Working
  meeting
• Currently optional, to become required for new
  and renewed certification from end 2009
• Testing run by / on behalf of Energistics
• Focus on data in key objects
• Standard query list, query tool and data set
• Future
• Expand object coverage
• Dialects
• WITSML client tools

Use Cases
17
WITSML Workflows

• Service Contractor to Service Contractor
• Service / Drilling Contractor to Operator 
• Application to Application
• Operator to Operator 
• Operator to Government

Example Sharing BHA info at the rig between
different service vendors operator reporting
systems Usage Reduce inefficient duplicate
entry of data. Improve quality of stored data

Application / Corporate Data store
User interface control
RT Torque-drag analysis
WITSML
Geoseteering

• Enhanced situational awareness
• Real-time engineering analyses in certified
  corporate tools
• Linear and most commonly uni-directional

19
Inter-Operator and Operator to Government

• Partner reporting
• Government reporting
• E.g. Norwegian NPD
• Increased automation
• Query-able data vs. pdf

20
More Complex Workflows

• Opportunity for Operator to apply Intellectual
  Property and gain competitive advantage
• Opportunity for Service Companies and Software
  Vendors to compete for delivering components even
  if not incumbent provider

What would success look like?
Service Companies

• Goals stated in Real Time/WITSML usage study1
• Access to the information I need to make
  time-critical decisions, regardless of who I am
  currently working with (as a Service Company)
• Save me 15 minutes a day, by not having to type
  in some data that is already in electronic format
  somewhere else
• Allow me to understand what is happening, at
  anytime, for any (drilling) operations, anywhere
• The ability to use drilling data from any
  technology provider within our (internal)
  processes for decision making
• Neutral way of encapsulating information so that
  it is available regardless of vendor, provider or
  version of their various technology

WITSML Measuring Progress

• Are we delivering the objective for the WITSML
  Standards?
• Enable decisions using Real Time data
• Proven, deployed solutions delivering real-time
  data for decision-making
• Simplify data interaction and data reuse
• 90 of data transferred is related to four WITSML
  data objects
• Limited use of Contextual and Reporting Objects
• Reduce complexity
• Incorporation of new data has moved from days to
  hours to minutes
• Some data errors still exist (Interoperability)
• Reduce cost
• Time savings
• 5 minute intervals on loading are now considered
  Maximum
• Technology Improvements
• Application use of real-time data increasing
• More accuracy
• Adoption and Use rate indicates value
