Job Description

Reports to: Subsurface Manager

Department: Subsurface


Main Roles & Responsibilities:

  • Responsible for developing and continuously updating high quality fully integrated static reservoir models for producing reservoirs, secondary and exploration targets including input to reserves update
  • To assist in updating field development and reservoir management plan
  • To design and supervise geological wells and data acquisition program and ensure that data is analyzed and interpreted accurately and made available in a timely manner
  • Assist in regional studies and evaluation and maturing prospects
  • Provide input to reserves studies


Key Accountabilities:

  • Build geocellular reservoir models (static models) including structural/stratigraphic framework, reservoir layering, distribution of reservoir rock-type, porosity, saturation, permeability, uncertainty analysis, volumetric calculations using state-of-the-art software and advanced technologies, and maintain and update them using the most recent additional data to allow for optimum resource management and hydrocarbon recovery from all reservoirs in line with the Field Development Plan and reservoir uncertainties
  • Integrate and manage geoscience and engineering data into geological models for visualization, analysis, evaluation and quantitative assessment
  • Use geological models as input to development and appraisal well planning
  • Team work with the reservoir team to end-up with changes in the static modeling compatible with the dynamic understanding
Development Geology
  • Responsible for developing and maintaining a detail knowledge of the geology of the Siba and surrounding fields reservoirs
  • Use geoscience data to define appraisal strategies, field development plans, by-passed hydrocarbon pay, infill well targets and enhanced hydrocarbon recovery programs
  • Work with members of subsurface and technical support team to ensure timely delivery of technical deliverables with highest technical standards
  • Provide technical support on all geological aspects to subsurface, TSC, drilling etc. and design best practice workflows that are tailored for working field
Wells and Reservoir Management
  • Provide geological input for the monitoring and analysis of well-by-well performance
  • Support definition of subsurface uncertainties for risk management and surveillance planning
  • Collect and analyze development well geological data
  • Assist in defining and updating reservoir management strategy as well as identifying incremental opportunities to add further reserves.
  • Contribute to well testing procedures and results evaluation. Understanding concept of reservoir simulation, reservoir displacement, reservoir geology & framework, (stratigraphy/sedimentation), Rock types and relation to reservoir properties
  • Contribute to well testing procedures and results evaluation. Understanding concept of reservoir simulation, reservoir displacement, reservoir geology & framework, (stratigraphy/sedimentation), Rock types and relation to reservoir properties
Operations Geology
