Designing horizontal wells in carbonate reservoirs using geological and hydrodynamic modeling tools
SOCAR PROCEEDINGS(2023)
摘要
The paper considers one of the ways to determine the optimal arrangement of production and injection horizontal wells in the Vereisky horizon, which formations are composed of interbedded carbonate and terrigenous rocks. The geological and production analysis of the drilled wells was carried out. Multistage hydraulic fracturing was used to increase the proportion of reserves involved in development. When drilling horizontal wells, using hydraulic fracturing, it is possible not only to increase the drainage zone of the target reservoir, but also to involve the above- and below-lying layers in the development. The performed analysis confirmed the high efficiency of horizontal wells with multistage fracturing. Various variants of arrangement of production and injection horizontal wells were designed and modeled using the geological and hydrodynamic model of one of the object's sections. Based on the performed analysis and calculations, the most effective schemes of well arrangements were selected
