EXPERIMENTAL STUDY OF GAS INJECTION ENHANCED OIL RECOVERY IN SHALE RESERVOIRS [PDF]

, 2019
Miscible gas injection enhanced oil recovery (huff-n-puff gas injection) has received increased attention especially in the unconventional plays like the Eagle Ford, where oil recovery is as low as 5 – 10% (Sheng, 2015). An increase in 1% of recovery

Study on the microscopic percolation mechanism of different aqueous media huff‐n‐puff with cores in Fengxi tight oil reservoirs of Qinghai Oilfield

Energy Science &Engineering, Volume 12, Issue 10, Page 4335-4354, October 2024.
Soaking period is the primary platform for injection medium interacting with formation fluid and reservoir rock in huff and puff. This work elucidated microscopic percolation mechanisms of different aqueous media and factors affecting the recovery degree in the soaking based on the establishment of huff and puff nuclear magnetic resonance physical ...

Tory Travails and Collegiate Confusion: The Oxford University Election of 1722*

Parliamentary History, Volume 43, Issue 1, Page 72-90, February 2024.
Abstract In terms of the unreformed franchise operative in the early 18th century, the University of Oxford made up an unusual parliamentary constituency. Here it was the votes of non‐resident members that could be decisive to the outcome if the seat was contested.

Acceptability and barriers of a GP–physiotherapist partnership in the diagnosis and management of COPD in primary care: A qualitative study

Health Expectations, Volume 27, Issue 1, February 2024.
Abstract Introduction Chronic obstructive pulmonary disease (COPD) is commonly diagnosed and managed in primary care but there is evidence that this has been suboptimal, with low confidence expressed in providing interventions requiring behaviour change.
