... on engineering and G&G analysis, it was decided to re-pressurize oil rim in Y Sand using gas of X Sand at virgin pressure. Considering Y Sand to be laterally extensive body, effect of gas injection at B-1 should be observed at wells B-2 and B-6 in the same structure. Nodal analysis was performed to estimate...

... Abstract Gas Assisted Gravity Drainage (GAGD) is a relatively new gas flooding Enhanced Oil Recovery (EOR) technique developed at Louisiana State University (LSU) to increase oil recovery by application of miscible and immiscible gas injection processes (using CO 2 , N 2 , and hydrocarbon...

... scenarios; a) when reservoir pressure is low and static liquid level remains below bottommost SPM, b) when there is a considerable liquid column in wellbore and gas injection pressures are limited due to surface constraints, injecting foam decreases the hydrostatic head and requires less gas injection...

.... These benefits help this technique to overcome traditional H 2 S processing and the problems of handling the elemental sulphur product, particularly for very sour natural gas streams. This paper discusses industry practices of acid gas injection with reference to their phase behaviour. Four stage acid gas...

... injection gas injection reservoir Introduction Pakistan's oil and gas resources are scattered throughout the country including lots of potential oil reservoirs. Pakistan's known approximate total oil reserves are 27 Billion barrels and approximate recoverable reserves are 936 Million barrels[ 1...
