OIL AND/OR GAS EXTRACTION SYSTEM AND METHOD

摘要

FIELD: oil and gas industry.SUBSTANCE: system for oil and/or gas production from underground formation includes the first group of wells distributed above the formation and the second group of wells distributed above the formation. The first group of wells includes a device for injection of carbon sulphur compound to the formation, and the second group of wells includes a device for oil and/or gas production from the formation during the first period of time. There is a device for conversion inside the formation of at least some part of carbon sulphur to other compound during the second period of time.EFFECT: improving efficiency of the method and reliability of the system owing to using mixed displacement of the product from the formation.21 cl, 7 dwg
