Waterflooding

Face-to Face Course

Noviembre 25 to 28, 2024

Duration : 4 days

COURSE DESCRIPTION

The course is an overview of the fundamental concepts of waterflooding:  pressure maintenance and displacement.  We will discuss the importance of petrophysical properties, geology, fractional flow theory and analytical models of sweep efficiency.  Behavior and results of several field cases will be reviewed.   Students should bring a laptop computer to class that has an installed version of Excel.

The course will be for geoscientists that have quantitative skills and have at least a B.S. degree.
