Significant strides in the use of enhanced oil recovery methods for oil production have been
established. Nevertheless, carbon dioxide enhanced gas recovery (CO 2-EGR) has …

Due to the combined advantages of injecting CO 2 for boosting natural gas recovery
efficiency and sequestration of CO 2 in depleted shale gas reservoirs, the enhanced gas …

Primary oil recovery from fractured unconventional formations, such as shale or tight sands,
is typically less than 10%. The development of an economically viable enhanced oil …

Tight gas reservoirs always have a low natural gas recovery because of the poor reservoir
properties. Effective means on achieving enhanced gas recovery (EGR) in this type of …

Adsorption of CH4, CO2 and 10% CO2/CH4 on mature Qusaiba shale (1.81% TOC) is
studied at 50, 100 and 150° C and 45 bars maximum pressure. Adsorption of CH4 was the …

To initially improve the gas production rate and shorten the payback period for tight gas
reservoirs, the multiple-fractured horizontal well (MFHW) model is always applied. However …

Enhanced gas recovery methods such as foamed CO2 are recommended for depleted gas
reservoirs. Viscoelastic surfactant (VES) is a form of a surfactant used for forming CO2 foam …

Vast reserves of unharnessed shale gas, primarily CH 4, present attractive and sustainable
energy resources as an alternative to the current conventional petroleum-based energy …

This paper reports the findings on the major factors affecting the hydrocarbon productivity
and ultimate resource recovery from the liquid-rich Duvernay Shale play in the Fox Creek …

Currently, it is difficult to accurately evaluate the recovery of tight gas reservoirs owing to its
poor physical properties, strong heterogeneity, high water saturation, complex percolation …
