FIELD: oil-and-gas industry.
SUBSTANCE: proposed method comprises drilling of heat-injection wells, injection of heat carrier into bed, drilling of vertical drain-extract well at the deposit center, dewatering and drying of bed and product extraction therefrom. Note here that heat-injection two-mouth wells are drilled of horizontal-circular profile in radius equal to that of isometric deposit. Drilling is performed by coiled-tubing process (flexible tube) with using of flexible tube as well casing. Said flexible tube is not cemented. Flexible tube is perforated toward deposit center and to vertical drain-extract well.
EFFECT: efficient extraction of bitumen and increased yield.
