Attic oil is usually defined as that oil which is trapped upstructure of the structurally highest producible well in a reservoir. If it is not economically feasible to drill a well for this oil accumulation, attic oil recovery by gas displacement is a possible secondary recovery method. The mechanics of the method are that gas is injected into the structurally highest well, the gas migrating up dip into the attic, forcing the oil downdip where it can be produced from the injection well or other wells in the reservoir. Where natural gas is in short supply or if injected gas cannot be recovered, inert gas generators for gas injection have a practical application. Oil accumulations found over and around piercement-type salt domes, such as the Bayou Des Allemands field, are usually excellent prospects for attic oil recovery by inert gas injection. After an economical comparison between recovery by natural gas or inert gas injection, it was found that the inert gas generator would be advantageous; therefore, an inert gas generator mounted on a cement barge was purchased. This study deals with this equipment which has now been in operation for one yr.
