EVALUATION OF OPERATION HORIZONTAL AND MULTILATERAL WELLS IN HARD-TERRIGENEOUS RESERVOIRS
Currently, the majority of fields in Western Siberia entered the final stages of development, there is a persistent decrease in productivity and increase in water production wells, require search and application of various stimulation techniques, including drilling and operation of horizontal and multilateral wells. One of these fields is Myhpayskoe, the development of which started in 1973. The analysis results show the efficiency of operation of multilateral wells is relatively directional, clear and indisputable. The main advantage of multilateral horizontal wells to provide a maximum contact area with the producing formation, leading to an increase in the drainage area of the well and reduce depression in the reservoir. But we recommend a final decision on the choice of the trajectory of multilateral wells taken after hydrodynamic modeling and feasibility study.
