Attic Oil Recovery

Operations to recover the attic oil will be conducted offshore using remote operated vehicle rov technology.

Attic oil recovery. 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. 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. 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. Gulf of mexico horizontal well improves attic oil recovery in active waterdrive reservoir.

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. 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. 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. Society of petroleum engineers.

There is a small portion of oil within the top dome of the brent delta cells. The beds are usually dipping at a high angle.
