Correlation Methods

Program Overview

Correct well-to-well correlation is the foundation of every structural map, reservoir zonation and static model; errors made here propagate into volumes, well placement and development plans. This course covers the subsurface correlation techniques used in field development: lithostratigraphic and log-based correlation, choice of datums and markers, sequence stratigraphic correlation of carbonate and clastic successions, biostratigraphy and chemostratigraphy, recognising faults, unconformities and facies changes, and correlating deviated and horizontal wells. Exercises use log suites from Gulf carbonate reservoirs, where subtle facies variations make disciplined correlation essential.

Learning Outcomes

• ✓Select appropriate datums and marker horizons for a field-scale correlation framework.
• ✓Correlate wells using gamma ray, resistivity, density and neutron log patterns while recognising facies changes.
• ✓Apply sequence stratigraphic principles to correlate carbonate and clastic reservoir intervals.
• ✓Identify fault cuts, missing or repeated sections and unconformities in well data.
• ✓Integrate biostratigraphic and chemostratigraphic data to resolve ambiguous correlations.
• ✓Build a consistent reservoir zonation for use in mapping and static modelling.

Target Audience

• Development and production geologists
• Petrophysicists
• Reservoir engineers involved in zonation and mapping
• Geomodellers and geoscience technicians
