PROJECTPROJECT

•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.

PMT PROJECTPMT PROJECT

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

DATA OBJECTSDATA OBJECTS

Status:

•Developed Fields.

•EOR/IOR Phase

•Now changed idea to implement PRODML which was earlier planned in Stage II.
