... including the avoidance of instabilities induced by flow pattern transitions is essential. This paper addresses this problem through laboratory measurements of steady and oscillatory components of flow-pressure under a broad range of gas injected rate and simulated reservoir pressures. Comparison...

... Abstract This paper presents the results of a full field compositional reservoir simulation study that compares the application of waterflooding and gas injection to a rich gas-condensate reservoir. Fluid (water or gas) injection is used to maintain the reservoir pressure above the dew point...

... Abstract A gas injection for the purpose of pressure maintenance was initiated in a field located in south of Iran in 1984. It is the largest gas injection project in Iran and possibly in the world without the use of compressors. The field was discovered in 1968. It consists of two non...

... strategy is pressure maintenance above bubble point by water injection. A WAG pilot was started in spring 1991. To improve evaluation of the pilot it was decided to inject tracers in the gas phase early in the first two gas injection periods. Production from the Sleipner field was started in August 1993...

... of gas. The initial reservoir pressure was 12,000 psi 15800 feet sub-sea. In order to develop and exploit this reservoir, a high pressure gas injection project is being considered both for partial pressure maintenance as well as for gas recycling purposes. With this in mind, a compositional...

... to optimally allocate gas to a group of wells in order to optimize total oil production. However, there is a disadvantage in this method, as it can not be applied to wells where there is not an instantaneous response to gas injection. The purpose of this paper is to present a methodology for automatically...

..., FRANCE. Preliminary studies performed in 1978 and 1979 have shown the technical feasibility and economic interest of injecting a significant quantity of inert gas (20 % of the cushion gas) before filling up the storage with natural gas.
