The task of developing carbonate reservoirs has now become extremely important. Low technological indicators of development are explained, as a rule, by an inefficient well placement system, complex geological structure, high oil viscosity, water breakthrough and the occurrence of technological complications in the process of field development. The aim of the work is to refine the geological and reservoir simulation model of a complexly built carbonate reservoir, in terms of areal coverage of wells by hydraulic fr...

Chemical flooding allows for the improvement of oilfield performance after standard waterflooding processes. Chemical EOR methods modify different properties of fluids and/or rock to mobilize the remaining oil. It is expected that the residual oil will be different in properties than conventional. A new technology is presented to study a surfactant-polymer flooding, based on a periodic sampling and measuring properties of oil and water during 15 months. At each sampling date, 2D reservoir model was built to track ...
