Methods, systems and devices that utilize a mobile offshore drilling unit (MODU) with other integrated equipment, hereinafter a mobile offshore production unit (MOPU) or a traditional floating production unit (FPU) to produce oil and natural gas from an oil and gas containing subsea geological formation are described. When the MOPU / FPU consumes all produced natural gas in one or more processes onsite to produce products selected from power, liquid petroleum products, hydrogen gas, solid carbon, and combinations thereof, then the production unit is transformed into a Modular MOPU™. Some produced natural gas is used to generate electricity for normal facility operations and additional natural gas consumed to generate electricity for various 4th-phase processes or used as feedstock for the production of value added products in processing equipment such as pyrolysis units, and / or gas-to-liquids units. Maximizing consumption of produced natural gas onsite, optimizes oil production without flaring, and without any export pipelines.

Described herein are methods and systems for enhanced oil recovery (EOR). The methods and systems are especially suitable for enhancing oil recovery in bottom-water drive producing formations having a gas cap where coning of bottom water is a problem. An external gas such as natural gas is injected into the gas cap. This essentially eliminates the bottom water drive and replaces it with top gas drive. The amount of gas delivered is calculated to replace the volume of oil produced from the well and maintain a constant pressure at the gas-oil interface, which maintains horizontal thrust to the production point and maintains a stable oil-water interface, preventing coning. The methods expand the area of oil recovery.

FIELD: oil production.SUBSTANCE: invention relates to a method and system for oil production. The extracted product is fed into the oil collection manifold. Reservoir pressure is maintained using injection wells. Water is pumped into the ejector nozzle. After measuring the flow rates of production wells, the associated petroleum gas is separated from the produced water-oil-gas mixture and pumped out using an ejector with the possibility of implementing wave modes of operation of oil production wells. The water-gas mixture is dispersed and the pressure is increased, followed by pumping the water-gas mixture into one or several injection wells and further into the formation using a booster pump. Reagents are dosed. Associated petroleum gas is separated from the water-oil-gas mixture together with pumping of the products of oil producing wells into an oil collection manifold using a frequency-controlled booster pump. The pressure is reduced at the mouth of oil production wells and in the annular space of oil pumping production wells, increasing the flow rate of oil production wells and increasing the flow rate of gas fed to the ejector intake. Wave modes of operation of oil production wells are implemented by means of joint frequency regulation of booster, charge and submersible well pumps.EFFECT: increase in the efficiency of oil production. The method includes the operation of oil production wells and measuring their flow rates.6 cl, 3 dwg
