Investigation of Well Equipment in the Oil Industry

Production rates from oil fields decrease over time due to various factors, so it is necessary to use methods that to some extent compensate for the reduction in oil and gas production rates. Gas overflow is one of the artificial overflow methods that is used with the aim of rehabilitating and increasing the optimal flow of oil wells. In this method, high pressure gas is injected at a certain point inside the fluid column in the well, thereby reducing the average density and subsequent pressure on the bottom of the well, and thus reactivating the well. In optimizing the operation, increasing the production and benefiting from the maximum operation of the well and its facilities are considered. In this project, two-phase current was model using a mechanistic model and parameters such as pressure profile, temperature, phase fractions and phase velocities are calculated. Then, with the help of node analysis, the natural production of the well is simulated and the need to use the method is investigated. When the reservoir energy (reservoir pressure) is not high enough for continuous production from the well, the artificial overflow method is used in oil production. Gas overflow method is one of the artificial overflow methods that is used to increase oil production from wells. In this method, high pressure gas is injected into the well to make the fluid column lighter and increase the reservoir pressure to produce oil.
