To maintain high rates of oil industry development and to attain sustained production, new oil fields have to be discovered with the reserves sufficient not only to provide for the planned production increment, but also to make up for production decline in the producing fields. So far as new discoveries are tapped by just one or two wells, areal limits of deposits have to be defined with maximum possible accuracy. To raise the accuracy of well spudding points, Tatneft Company uses detailed survey methods, in that number, broadside vertical seismic profiling (BVSP). Carrying out of the suggested program, taking into account the updated geologic model, prevents drilling of dry holes and allows attaining the project recovery factor.
