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 plant for injection of carbon sulphur to the formation, and the second group of wells includes a plant for oil and/or gas production from the formation during the first period of time. There is a device for conversion inside the formation at least of some part of carbon sulphur to other compound during the second period of time and a device for extraction of at least some part of the above other compound during the third period of time.
EFFECT: improving efficiency of the method and reliability of the device owing to using a solvent.
