WITSML FOR REAL TIME OPERATIONS
Well-site / platform

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

PANNA MUKTA TAPTI (PMT) PROJECT
15
PMT PROJECT

• Introductory Meeting held in Kolkata in Jan 2006
  during SPG.
• Attended by representatives from ONGC, BG
  Reliance.
• It was decided to go ahead with the Pilot in PMT
  JV because of its multi-operators environment.

16
DATA OBJECTS

• Data Objects for Stage-I (DrillingGG centric)
• Log Object (MWD, LWD, Wireline)
• Well / Wellbore object (well header information)
• Trajectory object
• Mud log object
• Stage-II planned as Production centric

17
PMT PROJECT

• Status
• Developed Fields.
• EOR/IOR Phase
• Now changed idea to implement PRODML which was
  earlier planned in Stage II.

WITSML IN SCADA PROJECT

• AN ENTERPRISE-WIDE SCADA (SUPERVISORY CONTROL AND
  DATA ACQUISITION) SYSTEM.
• WITSML COMPLIANT SERVER.

THE CHALLENGE
23
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.
