Fluids produced from oil and gas wells genrerally constitute mixtures of crude oil, natural gas, move upward into the gas cap and, thus, enlarge the gas cap.

As the expanding gas cap reaches the producing intervals of upstructure wells, the gas–oil ratio from the affected wells will increase to high values. Ultimate oil  7 Mar 2016 When oil is being produced, the gas cap expands and pushes oil downwards to a producing well (Figure 1). Figure-1---Gas-Cap-Drive. Abstract For a thin oil rim reservoir with a large gas cap on top and a strong is to keep the oil rim in continuous contact with the producing wells in the oil rim. However, the concurrent production of gas cap and oil rim is likely to cause the. ecological indicators of forest recovery on reclaimed oil and natural gas well  30 Jun 2017 The gas cap deposits, or oil rims, are a special type of deposits with the oil oil and gas condensate field, Kuyumba and Chona, as well as in  As wells are drilled and put into production, the reservoir pressure declines (but In saturated oil reservoirs, the free gas forms a Gas Cap (portion of the

[Well Completions] The gas that accumulates in the upper portions of a reservoir where the pressure, temperature and fluid characteristics are conducive to free gas. The energy provided by the expansion of the gas cap provides the primary drive mechanism for oil recovery in such circumstances. A gas cap present at the time of the discovery of the oil reservoir is known as a primary gas cap. Certain oil reservoirs are discovered with an initial reservoir pressure below the bubble point pressure where a primary gas cap forms long before the reservoir is discovered and produced.
