Technology for the development of residual reserves by water-gas methods in conditions of associated petroleum gas shortage [PDF]

open access: yesE3S Web of Conferences
A method for injecting a water-gas mixture is proposed, which takes into account the distribution of reserves in a formation anisotropic in permeability. A schematic diagram of a device for pumping a mixture into a formation is presented.

BIODESULPHURIZATION WITHIN NATURAL GAS IN OIL AND GAS FIELD

open access: yesMAKARA of Technology Series, 2010
The presence of sulphur compounds in natural gas can interfere to the quality of natural gas. The decline of combustion gas capacity, metal instrument corrosion in gas piping, and the environmental pollution from gas emission can affect by their presence. Bio-filter is one of the methods that selected to reduce sulphur content in natural gas.
