POSC DTS Standards in Shell

• Martijn Hooimeijer
• Linda Dodge

6
Why Shell Contributes

• Fits into Shell Data Architecture Standards
• Data handling and processing independent of DTS
  hardware vendors allows global standards, reduces
  interfaces
• Standard interfaces facilitate usage of best in
  class visualisation, interpretation and
  monitoring tools

What Shell has contributed

• Shell DTS Primer (a foundational document for the
  WITSML DTS definition)
• Integration expertise
• DTS Expertise
• Stimulating vendors to implement and comply with
  WITSML DTS

Envisioned DTS Architecture
Process Control Domain Storage required for 72
hours Data to be sent in POSC DTS ML Exchange
format.

• Transfer raw data (unscaled) Stokes /
  anti-Stokes data
• Transfer temperature traces
• Transfer other distributed data
• Flexible header that may include parameters
  relating to Light box, Fiber, and Well details.
• Transfer installation / hardware configuration
  (either as an extended header of regular
  message, or as separate message, with preference
  for the prior).

Shells plans

• An DTS data handling architecture has been
  designed around the WITSML DTS, including Oracle
  DTS Database
• First application using WITSML DTS due to be up
  and running in Q4 this year will probably
  generate change requests
• Continue working with all our DTS vendors to have
  their devices export WITSML DTS

Shell Standard Legend 2002

• Oil Gas Industry Standard Legend 1995
• Oil Gas Cartographic Symbology 2002

Usage in POSC

• Lithological vocabulary in the mudlog and
  sidewall core objects of WITSML 1.3.1 is derived
  from SSL.

Aspiration
- Industry take up- Adoption by vendors-
Embedding in tools
Vendor Tool 1
etc..etc..
Vendor Tool 2
Standardization within EP companies becomes
unnecessary or minimal

Curve Naming Standards in Shell

• Joined Curves
• Calculated / Interpreted Curves

Internal Implementing External....
16
Shell Curve Naming Standards vs. PWLS V2.0Joined
Calculated Curves

• SIMILARITIES
• Most maps comfortably
• DIFFERENCES
• Terminology
• DT vs. AC
• Granularity
• PWLS V2 Porosity does not have classes Net or Net
  Effective
• HC Saturation does not have any subclass
• Water Saturation does not have any subclass
  except Flushed Zone
• Resistivity Depths of Investigation does not
  differentiate Shallow and Micro
• Scope
• PWLS does not cover RFT pressures, TVD, FLD,
  LITH, Cased Hole, etc.
• Shell does not cover Minerals, Drilling Bit Size,
  etc.
• Flexibility
• Shell allows local specific for Volume Fractions
• Shell allows interpretation method as the suffix
  for all Calculated Curves

17
Change Requests and Results

• Acoustic
• Add Stoneley Slowness curve Accepted
• Replace AC with DT Not Accepted
• Resistivity
• Differentiate Shallow and Micro Accepted
• Permeability
• Replace LPERM with PERM Accepted
• Porosity
• Remove Total Porosity. Use generic Porosity
  instead Not Accepted
• Add Effective, Net Effective Accepted
• HC Saturation
• Add Net, Effective, Effective Net, and Flushed
  Zone Accepted
• Water Saturation
• Add Net, Effective, and Effective Net - Accepted

PWLS V2.0 Use in Shell

• Petris is working on implementing PWLS v2.0
  standard for Raw Curves in Recall by Shells
  request
• Plan to implement PWLS v2.0 for Raw Curves Names
  in Recall Standard Data Dictionaries
• Shell Global Standard on Joined and Calculated
  Curves implemented in Global Recall Data
  Dictionaries Deviations to PWLS V2.0 need to be
  revisited
• Shell is working on
• How and to what extend to use PWLS V2.0 (Raw
  Curves)
• Property Types
• Attributes
• Mapping between
• TechLog Curve Family
• Recall Curve Types
• PWLS Property Types
• Targeting to find alignment by end of year
