Attic Oil Recovery

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.

Attic oil recovery.

Society of petroleum engineers. 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. This paper presents a gulf of mexico field case study describing the use of horizontal wells to improve oil recovery in thin attic oil strong waterdrive reservoirs. The beds are usually dipping at a high angle.

Gulf of mexico horizontal well improves attic oil recovery in active waterdrive reservoir. 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. Brimmond group have recently completed the design manufacture and testing of an atex zone 1 category 2 attic oil recovery system for a global operator s decommissioning project. There is a small portion of oil within the top dome of the brent delta cells.

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. Attic oil reservoir recovery method.
