Annotation:
The development of productive formations by horizontal wells (hereinafter – HW) was able to show sufficient efficiency, including the operation of fields with various structural features of deposits and oil-saturated rocks, including high fracturing, presence of traps and the volume of porous space. From the point of view of oil deposits development by horizontal wells, the SAGD technology (TGDR) is very interesting. The technology of thermal-gravitational drainage of a reservoir (hereinafter referred to as TGDR) is a combination of the advantages of thermal treatments and horizontal wells, which allows its extremely effective use in fields with hard-to-recover hydrocarbon reserves. At the same time, regardless of the development technology and wellbore trajectory, the key tasks when monitoring the development of high-viscous oil deposits are the determination of wells and reservoirs parameters as well as prediction of oil production nature. At the same time, the use of certain drilling technologies and equipment, such as slotted or meshed liners, causes the occurrence of atypical phenomena in a well, which negatively affects the predictability of the hydrocarbon production process. The article discusses the prospects and features of using the field geophysics complex, including such logging methods as flow metering, thermometry and barometry in the development of reservoirs with horizontal wells and with the injection of a coolant in order to increase the control efficiency over the development of deposits, and increase the efficiency of the object development as a whole.
