Waterflood Design Surveillance and Implementation Course

Richard Baker

Waterflooding is by far the most commonly use improved (enhanced) recovery technique in the World for improving oil recovery factors. Understanding waterflood flow mechanics as well as operational factors is key to proper optimization. This is a case study based learning course.
Proper waterflooding management is different in:
• Conventional Oil Reservoirs,
• Higher Oil Viscosity Reservoirs
• Conventional Oil Reservoirs with Gas Caps
• Tight or Low Permeability Reservoirs
• Reservoirs with induced fractures
• Naturally fractured reservoir
Require different techniques. Therefore, the course addresses field examples in each case discusses practical surveillance.
Often the “operating” engineer has a rate and reserve forecast that often overestimates reservoir performance. This is generally a result of the reservoir/simulation engineer underestimates the severity of reservoir heterogeneities or operational (wellbore effects). There are numerous published analytical and simulation methods for the design of waterfloods; however, the literature has to a great extent been silent on reservoir surveillance to help monitor and improve existing waterfloods. This course tries to use field examples to surveil waterfloods, identify limiting factors and forecast and optimize waterfloods.Read more...
