The Design, Construction and Operation of a Sand Pack Model to Study the Use of Foam as a Permeability Blocking Agent
Abstract/Contents
- Abstract
- Non Newtonian fluids a r e often injected into a reservoir as part of an enhanced oil recovery process. Thermal recovery techniques and air injection have led to the flow of foams in porous media. In the state of California, a large portion of the oil reserve is in the form of heavy oil. Thermal recovery techniques, such as the injection of steam or insitu combustion, a r e the most effective means of recovering heavy oils.One of the major problems encountered in thermal recovery projects is the tendency of the injected fluids to pass through higher pemeability zones, missing the lower permeability zones. A second problem is gravity override. These two problems cause the thermal recovery projects to affect only the more pemeable and higher elevation zones. The most practical method of correcting this problem is to selectively block the fluid flow into the higher permeability and higher elevation zones.The injection of a permeability blocking agent would accomplish this. Scaled reservoir models have been used to study the effect of permeability variation and gravity override on oil recovery performance in frontal drive operations. Dyed fluids have been used so that the gross movement of the injected fluid can be observed.The purpose of this project was to design and construct a vertical sandpack model. The model will be used to evaluate the performance of foaming agents in permeability blocking.
