The Project A Vendor’s Perspective Samit Sengupta
Role of POSC Provides a platform to enable open collaboration between oil companies, service companies, application vendors and regulatory bodies
WITSML Data Objects • Well • Wellbore • Rig • Rig Equipment • Pump • Location • Units • Trajectory • Target • Bit Record • Bottom Hole Assembly • Wellbore Geometry • Casing Scheme • Open Hole • Daily Operations • Fluids Report • Cement Job • Log • Real Time • Mud Logging
Implementation Process Adapt Review SIG Analyze Release Pilot Steering Committee Technical Committee SIG Sub-teams
Case Study The Mudlog SIG Sub-team • Chair • Cary Fico (ExxonMobil) • Participants: • John Lottinville (BHI) • Lee Geiser (Petrolink) • Gary Masters (POSC) • Samit Sengupta (SDC Geologix)
