Prospect Appraisal

Generating a complete reservoir model

Hydrocarbon reservoir properties, connectivity, continuity, volume, and hydrocarbon type are usually determined by drilling additional appraisal wells within the accumulation discovered by the initial exploration well.

Seismic data are integrated with information provided by well logs to create an interpretation of the reservoir extent, geometry, and hydrocarbon content. Critical characteristics of the accumulation that need to be determined include

  • reservoir thickness and variation across the structure
  • oil-water, and gas-oil contacts
  • net-to-gross ratios
  • porosity and permeability
  • flow characteristics, fluid content
  • direct hydrocarbon indicators from the seismic data volume.

Integrating these measurements at all scales generates a comprehensive reservoir model with which to make decisions for further drilling.

Reservoir Definition

Reservoir studies can be designed to answer essential questions about the trap and structure, reservoir and seal.

The Next Phase

Once the static reservoir model has been developed further work needs to be carried out in order to assess performance under production.
