GAS LIFT AS A METHOD TO INCREASE OIL PRODUCTION BASED ON ENLARGING OIL DRAINAGE AREA

Oil production requires energy to raise fluids from the reservoir to the surface. The majority of oil wells flow naturally in the early stages of their product lifespan and are referred to as flowing wells. There is enough energy stored in the reservoir of a naturally flowing well to flow the generated fluid to the surface. Reservoir pressure and formation gas provide this energy in the flowing well. When reservoir energy is insufficient for natural flow, or when the targeted production rate is larger than the actual production rate, artificial lift is required to achieve the desired output. It is not economically viable to keep producing energy stable throughout the development of oil fields. Therefore, during the long-term operation of oil fields, the reduction of reservoir pressure and violation of the conditions of injection of wells leads to a decrease in the fluid level in the wellbore over time, making it difficult to lift the reservoir product to the surface. In this case, it is preferable to switch wells to gas lift operation. The presented article calculated the optimal parameters of the gas lift method on the reservoir-well model based on an actual well sample using the Prosper program. It determined how various parameters - the diameter of the production tubing and the skin factor - affect good production. Based on the project, it was determined that, in -2 negative skin factor and in 2.98 inches diameter of production tubing is optimum case for this well to increase the oil production rate. The purpose of the research is to determine the different trajectories of the well, the depth of gas injection into the well, and other parameters resulting from sensitivity analysis of the impact on sound production.
