Simply put, this difference (between the current cumulative production and the expected refrac EUR) should in theory be the "size of the prize" that one might hope to recover if the refrac was successful...

... 4 provided the highest oil recovery factor (RF) of 83% in condensate oil under immiscible conditions, while CO 2 and CH 4 performed the best with an RF of 67% in black oil reservoirs under miscible conditions. The performance of the solvent is impacted by fluid light components content...

... with the reservoir fluid. Simulations carried out using hydrocarbon gases with varying compositions of C 1 , C 2 and C 3 show recovery factors that are higher than C 2 injection. The results show that hydrocarbon gases with a higher C 1 content over C 2 , results in faster oil recovery during the initial cycles...

.... The results reveal that volume of oil produced to volume of oil in place ratio (recovery factor, Rf) increases with increasing Af/Vr ratio before reaching a plateau. This suggests that there is a threshold Af/Vr value beyond which an increase in Af/Vr will not result in any incremental recovery for a given...

... Abstract Over the last few years, many studies have shown promising results from CO 2 injection in tight formations which may lead to a significant increase in the recovery factor. However, disadvantages of CO 2 injection include equipment corrosion, reaction with formation minerals, limited...

... Abstract Laboratory experiments of gas injection in organic rich shales have resulted in significant oil recovery. In Part I (Tovar, Barrufet, and Schechter 2018), we presented an operational philosophy to maximize the recovery factor using a huff and puff injection scheme at the highest...

... modeling of different huff ‘n’ puff scenarios with both single-fracture stage model and DSU models. The single-fracture stage model showed incremental recovery factors ranging from 0.6% to 5.4%. This number could be increased by conducting more huff ‘n’ puff cycles over the lifespan of an operating well...

... Abstract The contribution from outside the Stimulated Rock Volume (SRV) to well performance is generally limited in shale wells (Ambrose et al. 2011) necessitating optimal well and fracture spacing. The well spacing is often also governed by the recovery factors per well or recovery factors...
