Application of combined fracturing in carbonate reservoirs of an oil field
Saint Petersburg Mining University, Department of Transportation and storage oil and gas, St Petersburg, Russia
This scientific work presents the design of combined acid fracturing in carbonate reservoirs of an oil field using mathematical modeling methods. An analysis of geological and technical actions was carried out, on the basis of which it was revealed that the previously used acid fracturing showed high efficiency, but at the same time there was a rapid rate of decline in production. In this regard, after studying various types of fracturing, combined acid fracturing is recommended to apply. It was found that the application of this method helps to increase the width of fracture and keeps it open, thereby compensating the lack of traditional acid fracturing.
