In this work, we investigate the efficient estimation of the optimal design variables that
maximize net present value (NPV) for the life-cycle production optimization during a single …

Fracture closure and proppant settling are two fully coupled processes during both shut‐in
and production. Proppant distribution greatly affects the residual fracture width and …

Conventional gas reservoirs are one of the viable options for CO 2 enhanced gas recovery
and sequestration. Injection of hot CO 2 into depleted reservoirs is expected to improve gas …

Recent improved and enhanced oil recovery (IOR and EOR) methods in shale reservoirs
use huff and puff gas injection (H&P). Investigating the technical and economic impact of this …

The dynamic nature of unconventional-reservoir developments calls for availability of fast
and reliable history matching methods for simulation models. Here, we apply an assisted …

Unconventional oil wells exhibit rapid decline in oil production rate and low ultimate oil
recovery, even though the lateral drilling and completion technology have advanced …

A sufficient number of choices are available when it comes to injection gas for enhanced oil
recovery (EOR) application in unconventional reservoirs, such as CO 2 and field gas to …

The application of non-hydrocarbon gas injection for enhanced gas and condensate
recovery (EGCR) is still in a developmental stage as the mixing/interaction between the …

During hydraulic fracturing of low to moderate (0.1–50 md) permeability reservoirs using
crosslinked gel fluids, the final proppant stage displacement is designed to leave some …

Lab experiments and numerical modeling have indicated that gas injection for IOR in tight oil
reservoirs is technically feasible. Several operators have conducted pilots in the Eagleford …
