The Longmaxi shale is an extensive, prolific unconventional play in southwestern China. Its
development in the Changning area is affected by ineffective hydraulic fracturing (HF) …

Shales are a central component of petroleum systems, as source, seal, and unconventional
reservoir rocks. Unlike traditional unconventional shale, a newly emerging Caney Shale …

Many geo‐engineering applications, for example, enhanced geothermal systems, rely on
hydraulic fracturing to enhance the permeability of natural formations and allow for sufficient …

The Duvernay Formation in Canada is one of the major oil and gas source formations in the
Western Canadian Sedimentary Basin, located at its deepest point. While it demonstrates …

ABSTRACT Enhanced Geothermal Systems (EGS) use hydraulic stimulation to improve
production from high temperature, relatively low permeability formations. EGS projects are …

Summary The emerging Paradox Oil Play in southeastern Utah is among the most
significant unconventional plays in the western USA. The mean total undiscovered oil …

Subsurface realizations are uncertain. Uncertain realizations are refined with additional
diagnostics and physics-based modeling establishes physical-plausibility of a realization …

Well spacing and hydraulic fracture design have an enormous impact on the economic
performance of wells in shale. Key design parameters include:(a) horizontal and vertical well …

A debris free, clean perforating tunnel with lower skin offers better reservoir connectivity,
better production and slower decline. An equal entry diameter perf-hole (EHD) creates a …

Creating accurate forecasts for inventory locations is challenging due to both the large
number of potential locations and the many variables impacting well performance. Future …
