OPERATED ONSHORE OIL FIELD DEVELOPMENT

Primary Purpose of the Job

Primary Purpose of the Job

Drive and perform Reservoir Engineering studies of the QatarEnergy operated onshore oilfields to optimize field development plans, support simulation models construction and maintenance, analyze reservoir and well performance data, develop reservoir surveillance programs and lead reservoir management activities. Drive and perform detailed/integrated development studies for developed and undeveloped hydrocarbon resources and participate in interdisciplinary reservoir study teams and sector reviews. Support staff coaching / mentoring / development.

Principal Accountabilities

Drive and undertake construction / model history matching and utilization of 3D multiphase black oil / compositional dynamic reservoir models for use in field development planning. Drive the development and delivery of optimized mid / long term strategic and tactical plans for the Operated Onshore field Assets. Assess and collaborate with others to address performance and production bottlenecks. Drive and perform the annual review of resources, generate long-term production/injection forecasts for Asset Planning, Business Planning and drilling/workover schedules. Drive and perform acquisition, and analysis/interpretation, of Reservoir Engineering data from new/replacement wells for updating simulation models and determining optimum plans. Ensure all data / analysis is input into integrated reservoir/field development studies. Drive planning and integration of Reservoir Engineering inputs into new drill / replacement / workovers projects and operations, reservoir voidage management, and field development / optimisation activities. Recommend / plan reservoir layer targets for infill drilling integrating fluid contacts, geological, production and reservoir engineering data. Drive and perform development of detailed, integrated development and maturation plans for developed and undeveloped hydrocarbon resources. Develop strategies and ensure implementation of mid / long term reservoir management plans. Develop surveillance programs that are efficient and effective. Mentoring and coaching of less experienced staff and share / leverage knowledge and skills across subsurface community.
