The impact of forced closure on proppant distribution of hydraulic fracturing in shale formations
Deep Underground Science and Engineering, EarlyView.Research findings demonstrate that implementing forced closure within shale formations can remarkably mitigate proppant settlement, concurrently increasing the effective propped surface area from 29.74% to 38.68%. Abstract Forced closure is widely used in conventional oil and gas reservoirs to promote uniform proppant placement.

Partial cavity instabilities [PDF]
, 1998 This paper reviews some of the literature on partial cavity instabilities on single hydrofoils and then summarizes the striking differences in the appearance and behavior of partial cavities on swept foils (as opposed to two-dimensional, unswept foils ...

core
Energy Science &Engineering, EarlyView.On the basis of core and log data, a Bayesian‐Optimized Random Forest model achieved 92.76% accuracy in classifying tight sandstone reservoirs. A gray relational analysis‐derived evaluation index shows > 80% consistency with actual gas zones. ABSTRACT Tight sandstone gas (TSG), an unconventional oil–gas resource, has heterogeneous reservoirs ...

Attenuation of multiphase surface waves in the Basin and Range Province-III. Inversion for crustal anelasticity [PDF]
Geophysical Journal International, 1994 SUMMARY A combined inversion/forward modelling procedure, in which the frequency dependence of shear-wave internal friction (Qμ-1) is allowed to vary with depth, was developed and applied to selected Rayleigh wave and Lg attenuation data in the Basin and Range Province of the south-western United States.
