Waterflooding Technical Courses and Training

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 (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 plots, WOR analysis, floodable pore volume versus primary depletion pore volume, injection profile testing, pressure transient testing, step-rate testing, Hall plots, pattern balancing, bubble maps, volumetric sweep evaluation, 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.

The course is ideally suited for engineers and geologists with several years of waterflood experience; however, the course is presented in a manner so that both beginning and experienced personnel will find the material very useful. The course content and example problems have been selected to teach and illustrate important concepts.

This course is available to the public several times a year; check the schedule for our next upcoming course. Upon special request this course can be taught in house, please contacts us for more information.
