                                                        presents a 3 day course:

                  Introduction To Waterflooding

          Who should attend and why?

This course is intended for engineers, technologists and geoscientists who wish to develop a solid understanding of the theory and practice of waterflooding.  The aim is to develop basic skills for designing and evaluating waterfloods based on fundamental understanding of multiphase flow and immiscible displacement in porous media. The course combines rock and fluid characteristics, immiscible displacement theory and practical considerations to develop water flooding 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, prediction of sweep efficiency (areal, vertical and displacement), the influence of vertical reservoir stratification, and the estimation of pattern injectivity are included. Also discussed are well completions and the sources and treatment of injection water.

Course Content:

·                 Primary, secondary and tertiary recovery concepts, review of rock and fluid properties, material balance calculations.

·                 Interfacial tension, wettability, capillary pressure, relative permeability, two-phase flow equations
