... Abstract Surface compressors lower the wellhead pressure and increase the tubing drawdown and hydrocarbon production. Hybrid use of surface compression, continuous flow plunger lift, and continuous gas injection reduces flowing bottomhole pressure and avoids liquid loading. The study focuses...

... Abstract Gas injection is one of the most widely used processes in the oil industry and is considered a promising enhanced oil recovery (EOR) method. Factors such as the injected gas type, minimum miscibility pressure (MMP) of injected gas, reservoir and fluid characterization can all...

..., the implementation of enhance oil recovery (EOR) techniques in shale resources is necessary for sustainable development. So far, several EOR techniques have been investigated to improve oil recovery from shale resources including gas injection (Gamadi et al. 2013, Chen et al. 2014, Sanchez- Rivera et al. 2014...

... Abstract Unconventional reservoirs through hydraulic fracturing produce higher initial volumes of oil while the decline rates are very high with low recovery factors. Enhanced oil recovery through cyclic gas injection has increased recovery factors in Eagle Ford. This paper focuses on multiple...

In this paper, we quantify the uncertainty in the enhanced oil recovery (EOR) for a pair of wells in the Permian basin, as well as report the lessons learned from modeling HnP EOR using reservoir simulation. We create a base sector model for two wells completed in Wolfcamp B...
