In frame of the project, one injector and two oil producers operating in different reservoirs having extremely high permeability were treated using the silicate/polymer method. The well selection based on analysis of production history, reservoir structure, and tracer test and production characteristics. The water cut in producers was close to or well above 90%. The chemical system was individually tailored to each well. The gel-forming solutions were sequentially injected into the wells using bullhead technique. The producers operating with sucker rod pumping were treated through the producing tubing or the annulus. In the latter case, a new "virtual" reactor concept was elaborated to mix the solution on the fly. Evaluating the results, it can be concluded that the project was successful. The cumulative daily oil production increased by 68 m3/d; meanwhile the water production decreased by 285 m3/d. Thus, on yearly basis, the incremental oil production might be as high as ~25,000 m3/y with water production less than 105,000 m3/y. The project clearly proved that the silicate/polymer technology could meet the requirements of the unique reservoir conditions (extreme permeability, faulted structure, and low formation temperature). In addition, great advantage of the composite methods is that easily available, cheap, and environmental friendly chemicals were used.
