Abstract
Oil production at the field takes several decades. The timing of oil production is influenced by the properties of rocks and fluids and the technological parameters established by the design documentation. In general, it can be noted that as the rock permeability improves and the crude oil viscosity decreases, the oil production time in the field will decrease. As the distance between the wells increases, the production process may slow down. A decrease in bottomhole pressure will lead to an increase in drawdown, which contributes to an increase in well production rates. However, with a decrease in bottomhole pressures in the bottomhole zones of wells, deformations of rocks occur. Deformation of rocks decreases the permeability. With a decrease in permeability, oil production time increases.
