Reservoir evaluation is a significant challenge in the HPHT environment. With current technology, the ability to assess rock and fluid properties is very limited. Utilization of an assortment of MWD, wireline, geochemical, and gas logging technologies is necessary when attempting to fully assess reservoir properties. All of these evaluation tools have significant limitations and proper well and evaluation program design and planning is critical. Success is often dependent on making several measurements and having contingency plans developed in the planning stage of the evaluation program. Actual HPHT well evaluation planning and execution examples, as well as, current tool limitations and future technology requirements are reviewed.
