Advances in Laboratory-Scale Hydraulic Fracturing Experiments

open access: yesAdvances in Civil Engineering, 2020
Hydraulic fracturing has been widely applied to stimulate the natural gas and oil production from unconventional reservoirs. To optimize the design of hydraulic fracturing in this application, an accurate estimation of the initiation and propagation of ...

Hydraulic fracturing proppants [PDF]

open access: yesCerâmica, 2018
Abstract Hydrocarbon reservoirs can be classified as unconventional or conventional depending on the oil and gas extraction difficulty, such as the need for high-cost technology and techniques. The hydrocarbon extraction from bituminous shale, commonly known as shale gas/oil, is performed by using the hydraulic fracturing technique in unconventional ...

Recycling wastewater for hydraulic fracturing by use of nanofiltration membranes [PDF]

open access: yes, 2014
Hydraulic fracturing creates large volumes of produced water, contaminated with organics, suspended solids, and dissolved minerals. This water must either be disposed of in injection wells or treated for reuse.

Hydrogel as a Medium for Fluid-Driven Fracture Study [PDF]

open access: yes, 2017
In this paper we describe how to construct polyacrylamide hydrogels to study the processes linked with hydraulic fracturing. These transparent, linearly elastic and brittle gels permit fracturing at low pressures and speeds allowing accurate measurements

Numerical simulation and engineering application of comb-shaped directional long borehole hydraulic fracturing under different arrangement of holes

open access: yesMeikuang Anquan, 2021
In order to avoid the blindness of the hydraulic fracturing of the directional long borehole in coal mine 2130 of Xinjiang Coking Coal Group, and to accurately grasp the extension and expansion of hydraulic fracturing under different hole layout methods,

Overcoming challenges in the classification of deep geothermal potential [PDF]

open access: yes, 2015
The geothermal community lacks a universal definition of deep geothermal systems. A minimum depth of 400 m is often assumed, with a further sub-classification into middle-deep geothermal systems for reservoirs found between 400 and 1000 m.

The Human Right to Water and Unconventional Energy [PDF]

open access: yes, 2018
Access to water, in sufficient quantities and of sufficient quality is vital for human health. The United Nations Committee on Economic, Social and Cultural Rights (in General Comment 15, drafted 2002) argued that access to water was a condition for the ...
