Field data on bottom-hole zone treatment has been analyzed. According to analysis results was revealed tendency of conducted measures quantity decrease. In the results of carried out intensification measures additionally produced oil allows in some degree compensating natural decrease of oil production. Due to this reason it is necessary to increase conducted measures quality and also increase their effectiveness. During statistical investigations of measures efficiency increasing issues is used the index average value of additionally produced oil on one conducted measure. In the results of carried out measures are given the following recommendations: - to reveal the wells and conducting type of intensification measures via well-known diagnostic methods; - the method of acid fracture treatment gives maximal increase in oil production in Muradkhanlyneft Oil and Gas Production Board (OGPB); - in Balakhanyneft and Bibiheybatneft OGPBs the maximum oil production increase is achieved due to the method of produced water isolation via foam-air system; - in order to increase surface-active reagent treatment efficiency via solvents and acid it is necessary to apply them in complex with vibro-ifluence; - in acid treatment it is necessary to provide selectivity; - during acid treatments in lower productive series objects it is necessary to increase reagent quantity for 1.5 times in comparison with the objects of upper productive series; - to estimate practicability of carrying out the measure by means of well-known forecasting methods.
