SR. PETROPHYSICIST
Overview
Responsible to plan, coordinate, supervise logging operations both open and cased hole logs for QatarEnergy operated offshore oilfields. Produce cost effective and comprehensive data acquisition plan for on-going drilling, workover operation as well as reservoir surveillance activities. Provide quick petrophysical analysis for appropriate completion strategy during drilling operation and generate post operation detail petrophysical interpretation and report to reservoir management team. Update and support Studies team regularly and as required. Ensure timely high data quality delivery from service providers for corporate archive. Being an active and highly supportive member of interdisciplinary reservoir management team.
Experience
Principal Accountabilities Plan, supervise the acquisition of IS field logging operations and analyse/interpret Petrophysical/Formation Evaluation data from new appraisal, development, and infill wells. Geo-steer horizontal and highly deviated wells to meet target reservoirs. Provide petrophysical input into integrated reservoir/field development studies for subsurface model building and updating. Develop Petrophysical model to characterize reservoir fluids for 3D geostatic/reservoir simulation modelling and field development planning, ensuring that Petrophysical uncertainty ranges are captured and understood. Develop, contribute, and integrate Petrophysical/Formation Evaluation inputs into the short term (drill/replacement well projects, workover projects and drilling operations), medium term (reservoir voidage management) and long term (field development and asset value optimisation) activities. Characterize reservoir fluid type, saturation, and distribution for identifying and recommending new/replacement drill and workover subsurface targets for producers/injectors/observers to optimize field development. Integrate both open and cased hole logs as well as core routine and SCAL data to better characterize the reservoir and fluid properties. QA/QC Petrophysical data and maintain Petrophysical databases including real time data links.
