Increasing the efficiency of the Aptskaya deposit development in the North Caspian fields using multi-hole wells with intelligent completion

The development of oil fields is a complex multi-stage process that requires the use of advanced technologies to maximize the extraction of hydrocarbons and ensure economic efficiency, especially in offshore fields where capital costs are several times higher than onshore. In one of the fields in the Northern Caspian Sea, two wells were drilled into an Aptian reservoir as part of an experimental development. However, the planned flow rate was not achieved after a multi-stage hydraulic fracturing (MSHF) due to the high gas factor. The Apt deposit of the fields, characterized by specific geological conditions and collector heterogeneity, poses a number of challenges for specialists related to the optimal opening of the productive reservoir and production management. The decrease in production dictates the need for the development and application of technologies that can increase oil recovery and extend the life of wells. The use of multi-borehole wells (MBW) in combination with intelligent completion systems (ICS) opens up new prospects for the efficient development of reservoirs with low filtration and capacity properties, which includes the Apt deposit of the North Caspian fields. MGS allows to increase the area of the reservoir coverage and increase the drained volume, while ICS provides the possibility of operational control by zones and control of the extraction process in real time. Traditional methods of development often prove to be insufficiently effective in such conditions, which causes the need to search for and implement innovative approaches. When working out the optimization of the design solution, with the direct participation of the authors of the article, it was proposed to change the design of wells from MSHF to multilateral execution.
