COURSE DESCRIPTION

This five-day course covers the reservoir engineering aspects of waterflooding. The seminar combines geology, rock and fluid properties, and immiscible displacement theory to develop waterflooding prediction techniques and to aid in the evaluation of actual waterflood performance behavior. Detailed predictions of oil and water producing rates, water injection rates, and recovery efficiency are presented. Selection of waterflood patterns (regular, irregular, peripheral), prediction of sweep efficiency (areal, vertical, and displacement), and an analysis of other variables which control recovery efficiency are included. Also discussed are waterflood surveillance techniques such as production testing, production plots (rate-time, rate-cum, WOR-cum, etc.) volumetric sweep (reservoir conformance) evaluation, injection profile testing, pressure transient testing, step-rate testing, Hall plots, pattern balancing, bubble maps, and injection efficiency determination. These surveillance techniques provide the engineer with data required for the efficient management of both new and mature waterfloods. Several waterflood case studies are reviewed.
