The results of scientific researches and practical work prove that although oil-gas deposit of Gharachukhur has been exploited more than 80 years its perspective opportunities are high and it has a large amount of oil residue for increase of oil extraction. It has determined that most part of Gharachukhur deposit has been surrounded by the high pressured displacement system of Bine-Hovsan and Baki moulds and it has influenced on technological indicators of exploiting objects. The industrial operation of the deposit was started in 1928 and in the first stage the speed of oil extraction was high. By the reason of decrease of the number of wells and fall of extraction only 14% of oil was extracted. The horizons of top section of the productive layer (PL) were exploited more intensively than under section. Carried out researches show that under section was provided with the operation weakly, 88.0 % of oil residue gathered here. So, perspectivity of the deposit is mainly related to the under section of PH. It is considered so that the application of artificial influence on the layers which are related to the high pressured displacement system would be both technological and unproductive from a technological and economical standpoint. For extracting of oil residue existing layer energy will be enough. According to current operation the deposit is being exploited at a very low speed. Sparse well net, especially its not being in the under section of PL causes it. Increase of the number of active wells is demanded to raise the level of oil extracting in the deposit. For it, exploitation of a number of perspective wells must be restored in the fund of passive wells, new wells must be drilled and the method of second tube boring must be applied widely. It is known that, layer waters of the deposits are rich with industrially significant microelements and salts. So, production of microelements from layers can make complete exploitation of the deposit productive from an economical, technological and ecological standpoint.
