Reservoir Management and Well Decommissioning

Reservoir Management and Well Decommissioning

  • Develop cased hole data acquisition strategies

  • Plan and deliver production logging programs

  • Interpretation of reservoir monitoring logs: production, saturation logs

  • Interpretation of cement and casing integrity logs

  • Formation Evaluation for reservoir management and remaining oil

  • Formation Evaluation support to well decommissioning

The evaluation of saturation uncertainty from well logs together with quality control and integration of special core analysis data allowed a confident revision of the residual oil saturation for the field, the improved history match of the dynamic simulation and a more confident assessment of remaining oil resources.
