... providers. Understanding the mechanisms of H2S generation might reduce the risk of souring in new wells and enable more effective mitigation and management strategies in the wells already producing sour gas. Multiple known mechanisms can potentially lead to H2S occurrence in the oil production stream...

... medium consisted of two types that are simple trapping mechanism designs (converging-diverging channel and pore doublet) and sample rock-like designs (sandstone and fractured sandstone). The experimental results confirmed that ferrofluid is an effective enhanced oil recovery agent for both the wetting...

Finally, the influence of various physical mechanisms, such as convection and diffusion, and the contribution of the pore and fracture networks, are examined using dimensionless pressure variations with time. CO 2 transitions...

Subsequently, we implement an adversarial training strategy using the generative adversarial network (GAN) framework. With this strategy, the model will converge to a Nash...

... often occurs. One of the main mechanisms of casing deformation is shear slip on weak planes, i.e. natural fracture reactivation during injection operations. The formation pore pressure near wellbore increases as fracturing fluid is injected during hydraulic fracturing, and the stress state near wellbore...

Calibration Model Validation Using Child Wells: Applied calibrated fracture and reservoir model to offsetting wells Investigation in Phase 1 indicated that individual mechanisms for Stimulated Rock Volume (SRV) degradation could account for some of the observed production trends. However, additional...

The resulting geo-mechanical compaction curves demonstrate significantly more permeability degradation for the aggressive drawdown case compared with that of the moderate drawdown. Simulation demonstrates aggressive drawdown only reduces pressure near the fracture, while...
