A number of different geological and production parameters affecting successful acid fracturing are considered in the conditions of carbonate reservoirs of oil fields in Bashkortostan. The study results are of use for assessing the effectiveness of geological and technical measures and for a more reasonable choice of candidate wells for acid fracturing.

To date, an increase in the oil recovery factor by commissioning horizontal wells is of relevance for oil fields at the late exploitation stage. In most cases, horizontal wells are developed using multistage fracturing; therefore, it is crucial to determine the criteria affecting its successful implementation. The study results are of use for a more reasonable approach to the choice of the location of horizontal wellbores and increase in the efficiency of geological exploration and multistage hydraulic fracturing.
