METHOD FOR DEVELOPMENT OF DEPOSIT OF HEAVY OIL OR BITUMEN WITH IMPLEMENTATION OF TWO WELL HEAD HORIZONTAL WELLS Russian patent published in 2011 - IPC E21B43/24 

FIELD: oil and gas production.

SUBSTANCE: procedure consists in construction of double well-head horizontal wells, in heat carrier pumping through upper - pressure well with payout bed heating and creation of steam chamber, in withdrawal of production through lower - producing well, in pickup of thermogram of steam chamber, and in analysis of condition of its heating for uniformity of heating and presence of temperature peaks. The steam chamber is uniformly heated on base of obtained thermograms. A process double well head wells is constructed above the pressure well at distance eliminating outbreak of heat carrier. Pickup of steam chamber thermogram is carried out on data of thermo-sensors positioned in process and producing double well head horizontal wells. Geo-physical analysis is performed from side of both well heads for control of uniformity of steam chamber heating. During development of deposit of heavy oil or bitumen production from both well heads is periodically sampled for evaluation of salinity of samples water. Salinity of water is correlated to presence of temperature peaks on thermograms of the steam chamber, where upon there changed filtration direction and/or modes of heat carrier pumping and withdrawal of production for equalising temperature in the steam chamber.

EFFECT: raised efficiency of procedure.
