Attic Oil Recovery

Recovery of this attic oil in geologically complex reservoirs with conventional vertical or directional wells is in general not cost effective because of the reduced vertical column of oil in place and the ease of water coning.

Attic oil recovery.

The three skid system consisted of a duplex filtration skid with differential pressure gauge a pneumatically powered pump skid and a metering skid to which a multi phase flow meter will be fitted. In a conventional attic oil reservoir recovery program wherein gas is injected through a well into an attic reservoir the gas then migrating updip and displacing oil downward to the producing interval in the well wherefrom the oil is then produced the improvement is added wherein at the completion of the gas injection step a water excluding agent is injected into the reservoir in the immediate vicinity of the well bore which prevents the formation water from restricting the flow of oil. Operations to recover the attic oil will be conducted offshore using remote operated vehicle rov technology. The oil cannot be recovered with the internal process piping due to the design of the cell outlet piping and the fact that oil is buoyant on water.

The beds are usually dipping at a high angle. In a conventional attic oil reservoir recovery program wherein gas is injected through a well into an attic reservoir the gas then migrating updip and displacing oil downward to the producing interval in the well wherefrom the oil is then produced the improvement is added wherein at the completion of the gas injection step a water excluding agent is injected into the reservoir in the immediate vicinity of the well bore which prevents the formation water. Gulf of mexico horizontal well improves attic oil recovery in active waterdrive reservoir. Attic oil reservoir recovery method.

There is a small portion of oil within the top dome of the brent delta cells. Newer research on residual oil zones has shown enough promise that researchers claim it could unlock 800 billion even a trillion new barrels to recovery just in the permian basin.
