Fluid diversion and sweep improvement with chemical gels in oil recovery processes
The objectives of this project are to identify the mechanisms by which gel treatments divert fluids in reservoirs and to establish where and how gel treatments are best applied. Several different types of gelants are being examined. This research is directed at gel applications in water injection wells, in production wells, and in high-pressure gas floods. The work will establish how the flow properties of gels and gelling agents are influenced by permeability, lithology, and wettability. Other goals include determining the proper placement of gelants, the stability of in-place gels, and the types of gels required for the various oil recovery processes and for different scales of reservoir heterogeneity. This report describes progress made during the first year of this three-year study the following tasks: gel screening studies; impact of gelation pH, rock permeability, and lithology on the performance of a monomer-based gel; preliminary study of the permeability reduction for CO{sub 2} and water using a resorcinol-formaldehyde gel; preliminary study of permeability reduction for oil and water using a resorcinol-formaldehyde gel; rheology of Cr(III)-xanthan gel and gelants in porous media; impact of diffusion, dispersion, and viscous fingering on gel placement in injection wells; examination of flow-profile changes for field applications of gel treatments in injection wells; and placement of gels in production wells. Papers have been indexed separately for inclusion on the data base.
