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

PROJECT
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.
DATA OBJECTS
Data Objects for Stage-I (Drilling+G&G centric)
•Log Object (MWD, LWD, Wireline)
•Well / Wellbore object (well header information)
•Trajectory object
•Mud log object
Stage-II planned as Production centric
PMT PROJECT
Status:
•Developed Fields.
•EOR/IOR Phase
•Now changed idea to implement PRODML which was earlier
planned in Stage II.
