Fracturing/pressure pumping
In this work, microseismic observations are integrated with strain and other observations to investigate the microseismic response in relation to the underlying hydraulic fracture geometry for different rock types.
This work proposes a method to interpret far-field strain-change and pressure data to quantify fracture connectivity and properties at the cluster level.
Modern completions often are equipped with downhole measurement devices that provide critical real-time data not only during the hydraulic fracturing treatment but also during the ensuing production phase.

This paper contains a detailed discussion of methods and a software tool that has been developed to generate information that predicts formation-face pressures in real time with the help of live bottomhole-pressure data. -
This paper presents a newly developed model to predict the breakdown pressures in cased and perforated wells.

As gas development focuses more on tight and ultratight formations, the challenges to produce economically become diverse and more intense. One main challenge faced while fracturing a well is a high fracture gradient.

This paper presents a newly designed triaxial fracturing system and describes a series of experiments that verified the validity of tool-free chemical diversion for multistage fracturing of openhole horizontal wells.

This paper presents a unique work flow that addresses in real time the challenges of perforation and fracture-treatment design while accounting for the lithologic and stress variability along the wellbore and its surroundings.

In this study, a laboratory analysis was conducted to study the effect of a phosphonate-based scale inhibitor on a mixture of hypersaline Arabian Gulf seawater and formation water under high-temperature/high-pressure conditions.

The very first fracturing job used sand scooped from a nearby river. After decades of buying sand based on tight size standards, unconventional operators are increasingly going back to a broad range of sizes, similar to that river sand.

"I have some patients whose symptoms I can’t explain," physician Ulrike Meyer said, describing nosebleeds, rare cancers, and respiratory illness among a dearth of data.
