This arrangement allows a deeper gas injection in the tubing.
An intermitter at the surface controls the timing of the gas injection.
Recovery is done through pressure maintenance utilizing both water injection and water alternating gas injection.
From 1916 to 1940 the well utilized primary production, adding secondary methods of gas injection (1941 to 1948) and waterflooding (since 1948).
Both methods also have been used on the Colonia pool, with gas injection running from 1964 to 1971, and waterflooding since 1960.
North American natural gas injections (positive) represent additional demand and compete with alternative uses such as gas for heating or for power generation.
As natural gas injections (positive) represent additional demand, withdrawals (negative) represent an additional source of supply which can be accessed quickly.
Direct coal/natural gas injection reduces demand for metallurgical coke.
The operation recently expanded its sour gas injection and second generation plant facilities to increase production and recovery levels.
The gas is also transported to Grane oil field for gas injection.
