Development of new technologies to increase sweep efficiency in heterogeneous reservoirs implies application of new agents and their mixtures. A number of scenarios are proposed for various reservoir conditions based on the results of simulation of oil displacement with guar gum solutions and gelling agents. At present the technology is being fieldtested in Tatneft assets.
