Crushing and embedment of proppant packs under cyclic loading: An insight to enhanced unconventional oil/gas recovery

K. M. A. S. Bandara et al.

Summary: Crushing and embedment are critical downhole proppant degradation mechanisms affecting production in unconventional oil/gas projects. This study recommends using ceramic proppants, larger sizes, and higher concentrations to mitigate crushing issues in high stress fracturing stimulations, while resin-coated proppants may reduce embedment. Smaller sizes and higher concentrations are suggested for projects at depth with lower stresses. Stay tuned for further research on proppant embedment effects.

Experimental study on the effects of pre-cracks, fracturing fluid, and rock mechanical characteristics on directional hydraulic fracturing with axial pre-cracks

Zhenghe Liu et al.

Summary: The study shows that the inclination angle of pre-cracks affects the fracture initiation pressure and extension length, while a longer pre-crack length reduces the fracture initiation pressure. Additionally, increasing fracturing fluid viscosity significantly increases the crack extension length.

Analysis of capillary water imbibition in sandstone via a combination of nuclear magnetic resonance imaging and numerical DEM modeling

Teng-Fei Fu et al.

Summary: Understanding the physics of water imbibition into initially unsaturated sandstone is crucial for displacement processes and fluid transport in the vadose zone. Utilizing NMR technology, researchers visualized and quantified the dynamics of water infiltration and distribution in the sandstone. The study also involved developing an analytic function to estimate sandstone moisture profile and incorporating a three-dimensional discrete element grain-based model to simulate water imbibition process and evaluate its impact on mechanical properties of sandstone.
