Abstract
Disclosed is a less expensive, more efficient process for enhanced oil recovery, particularly useful in high cost environments such as offshore. This process is known as single well gas assisted gravity drainage (SW-GAGD). The process comprises the steps of drilling from a single wellbore one or more horizontal laterals near the bottom of a payzone and injecting a fluid displacer such as nitrogen or carbon dioxide through injection points. The injectant sweeps the oil and other produced fluids in the reservoir towards other producing perforations in the single well.
