LOG DATA MANAGEMENT IN EPINET

• Log Data Management is an integral part of
  EPINET.
• Original Logs are managed in LogDB in original
  format.
• Edited and spliced logs (Composite Logs) are
  managed in Finder.
• Web Based data delivery from both LogDB as well
  as Finder.

CURVES WHICH ARE SPLICED AND LOADED INTO FINDER

• Deep resistivity (if different type of tools are
  run in different intervals LLD/ AT90 /RLA5/GRD)
  or 3/6 resistivities (if same type of tool is run
  in all the intervals LLD, LLS, MSFL / ILD, ILM,
  LL3 / GRD, SGRD, FRXO / AT 90, AT 60, AT30,
  AT20, AT10, RXOZ / RLA5, RLA4, RLA3, RLA2, RLA1,
  RXOZ)
• Density (RHOB / RHOZ)
• Neutron Porosity (NPHI)
• Sonic (DT / DTCO / DTL / DTLN / DTLF)
• Gamma Ray (GR / SGR / GKUT)

11
CURVES WHICH ARE LOADED INTO FINDER RUNWISE

• Self Potential (SP)
• Resistivity (LLD, LLS, MSFL / ILD, ILM, LL3 /
  GRD, SGRD, FRXO / AT 90, AT 60, AT30, AT20, AT10,
  RXOZ / RLA5, RLA4, RLA3, RLA2, RLA1, RXOZ)
• Density (RHOB / RHOZ) along with DRHO PE
• Neutron Porosity (NPHI)
• Sonic (DT / DTCO, DTSM, VPVS / DTL / DTLN, DTLF)
• Gamma Ray (GR / SGR / GKUT)
• Spectral Gamma Ray (SGR, CGR, THOR, URAN, POTA/
  HSGR, HCGR, HTHO, HURA, HFK)

12
CHALLENGES FACED

• Two different types of tools are used in
  different intervals.
• DLL-MSFL-GR (deep resistivity LLD) recorded in
  the top interval
• AIT-MCFL-NGS (deep resistivity AT90) recorded in
  bottom interval
• Proliferation in the number of curve mnemonics
• A large number of Logging While Drilling (LWD)
  curve mnemonics have further compounded the
  problem

13
SOLUTION TO THE PROBLEM

• PWLS
• Practical Well Log Standards (PWLS) Special
  Interest Group (SIG) of Energistics has come out
  with a solution to this problem. PWLS is now part
  of Geology SIG of Energistics.
• PWLS has standardized the curve mnemonics of
  spliced (joined) curves.

KEY BENEFITS

• Simplified curve mnemonics.
• User friendliness.

24
ROAD AHEAD

• Organization wide implementation.
• Implementation in Finder n-list itself.

IMPLEMENTATION OF WITSML
26
OBJECTIVE
To facilitate right time seamless flow of
well-site data in multi-vendor multi-operator
environment to speed up and enhance decision
making
27
WITSML FOR REAL TIME OPERATION
28
WITSML FOR REAL TIME OPERATIONS

• ONGC, Paradigm and Halliburton developed a
  software (2003).
• Interact Insite (2004 onwards)
• LWD/MWD objects.
• Used for Geo-steering in Mumbai High.
• Also used for deep water exploration

THE CHALLENGE
34
SEAMLESS INTEGRATION OF SAP EPINET WITH SCADA

• FROM WITSML COMPLIANT SCADA
• TIME STAMPED DATA WILL FLOW INTO ICE-SAP FOR
  BUSINESS COMPUTATIONS.
• THE E P DATA WILL FLOW TO EPINET.
