The invention relates to the oil producing industry and is intended for development of extra-viscous oil deposits through horizontal wells with thermal bed stimulation.
Application of this technology provides for enhancing the efficiency of the deposit development by increasing the reservoir sweep efficiency through thermal stimulation.
At present this method is being implemented in seven pairs of horizontal wells at Ashalchinskoye field of TATNEFT and allows improving the accuracy of monitoring the uniformity of heating the steam chamber by controlling the heat carrier injection mode and total liquids production.
