While waterflooding is a standard method used to develop terrigenous reservoirs, for development of carbonate reservoirs Tatneft OAO extensively uses horizontal technologies, that is, drilling and operation of wells with complex configuration including horizontal and multilateral horizontal wells. Horizontal technologies help to decrease total number of planned wells as well as optimize technical and economic performance of reservoirs under development. The main benefit of horizontal drilling become available.
