Use of DST for Effective Dynamic Appraisal: Case Studies

In the west Africa deep offshore region, most turbiditic-series reservoirs are structural traps with a stratigraphic component and severe faulting. Evaluation of connectivity and characterization of the reservoir heterogeneities before development decisions are the main challenges. Two extended drillstem tests (DSTs) acquired at a relatively early stage of the appraisal had a significant effect on the development projects.
