Primary Purpose of the Job

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

Principal Accountabilities

  • Undertake construction / model history matching and utilization of 3D multiphase black oil / compositional dynamic reservoir models for use in field development planning.
  • Development and delivery of optimized mid / long term strategic and tactical plans for the Operated Onshore field Assets.
  • Assess and support others to address performance and production bottlenecks.
  • Perform the annual review of resources, generate long-term production/injection forecasts for Asset Planning, Business Planning and drilling/workover schedules. 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.
  • Planning and integration of Reservoir Engineering inputs into new drill / replacement / workovers projects and operations, reservoir voidage management, and field development / optimisation activities.
  • Assess / Identify drilling opportunities / portfolio and recommend reservoir layer targets integrating fluid contacts, geological, production and reservoir engineering data.
  • Perform detailed and integrated development and maturation plans for developed and undeveloped hydrocarbon resources.
  • Develop strategies and ensure implementation on mid / long term reservoir management plans.
  • Mentoring and coaching of less experienced staff and share / leverage knowledge and skills across subsurface community.

Decision Making Authority

  • Within the broad guidelines set by Supervisor and the Department mandates, perform and support assigned activities and deliver recommendations. The incumbent is accountable for own decisions , actions and outcomes.
  • Work requires regular monitoring and support by Supervisor and Delegated Staff

Context / Special Features / Challenges

  • Identify solutions to wide-ranging problems involving multiple disciplines.
  • Identify uncertainties and develop mitigations/solutions.
  • Ensure that relevant environmental and safety standards are enacted for all activities.
  • Produce high quality but “fit-for-purpose" work.
  • Be able to take responsibility and accountability over the assigned tasks.
  • Routinely gathers and transfers knowledge across the organization.
  • Building of strong network throughout organization is required for effectiveness in role.
