Predicting the Method of Oil Recovery in the Gas-assisted Gravity Drainage Process
Petroleum Science and Technology, 2013Gas-assisted gravity drainage (GAGD), solving the problem of low volume sweep coefficient for continuous gas injection (CGI) or water-alternating-gas injection (WAG) and increasing the ultimate recovery to a great extent, is a latest method for enhancing oil recovery. However, no effective predicting methods of oil recovery for GAGD exists.

Abstract The main types of non-rod pumps such as the electrical submarine, piston, and jet pumps often have high discharge capacities. In this paper, the process parameters design method of a new non-rod gas-driven pump is proposed for carrying coal power, low discharge capacity, and low lift height drainage gas recovery in coalbed methane production.

Sustainable Strategy for Gas Supply in China: Based on Foam Drainage Gas Recovery Technology
Strategic Planning for Energy and the Environment, 2023With the increasing demand of natural gas in China, its production is extremely important to fulfill the requirement of society. However, in reality, the natural gas production from the gas well in the gas field is often accompanied by the production of formation water. For gas well with low production, the gas flow rate in the well is too low to carry

Abstract The accumulation of fluid in the wellbore of a natural gas well can seriously affect the production of the well and can even lead to the well flooding and stopping production. The conventional cyclone tool has low kinetic energy, serious energy loss and short effective distance of spiral flow in the process of gas well ...

Oil Recovery by Gravity Drainage during Gas Injection
IOR 1995 - 8th European Symposium on Improved Oil Recovery, 1995This paper presents the results from six gravity stable gas injection experiments in 1.2 m long water flooded sandstone cores. All experiments were performed close to ambient conditions with different combinations of spreading and wetting characteristics for time periods of 50 to 170 days.
