FIELD: oil industry, possible use for extracting deposits of high viscosity oil or bitumen.
SUBSTANCE: in accordance to method, a row of parallel extractive two-mouth horizontal wells is built. Above the row of parallel extractive two-mouth horizontal wells, in parallel to it, a row of forcing parallel two-mouth horizontal wells is built with position between extracting wells in plane of force wells. Water steam is forced through a row of parallel force two-mouth horizontal wells with forcing of steam through both mouths of each one of forcing two-mouth horizontal wells. Product is extracted through a row of parallel product two-mouth horizontal wells. In gaps between product and forcing two-mouth horizontal wells flat-lying force wells are built, through which dissolvent of high viscosity oil or bitumen is forced.
EFFECT: increased pace of warming-up and of oil extraction.
