Definition of the Day – Oil & Gas Life Cycle “Appraisal”

The exploration phase of the oil and gas life cycle closely intertwines with the next stage of the process which is APPRAISAL.  The objective of Appraisal is to obtain information about the reservoir to decide whether or not to proceed with development of the field. This stage is comprised of the following activities:

  • Planning and execution of a data acquisition program of additional seismic,
  • Reprocessing existing seismic data to obtain enhanced results and the drilling of
  • Appraisal wells
  • Evaluation of the results from the seismic and appraisal drilling activities
  • Using the information from the seismic and drilling programs to update the computer reservoir simulation models
  • Conduct initial conceptual field development planning and an environmental impact assessment (EIA) study of these conceptual plans
