Reliability and Applicability of DSTs and Bottomhole Pressure Measurements in Texas Gulf Coast Tertiary Formations

摘要

Pressure data gathered from drillstem tests (DSTs) and bottomhole pressure measurements provide critical information toward formation evaluation and can be used for an assessment of prevailing pressure regimes and their influence on the migration potential of formation fluids. Reliability of such pressure data is an issue of major concern in reservoir engineering practice and can be established through an appropriate screening procedure.
