Experimental assessment of the stability and impact of water-based fracturing fluid with and without Triethanolamine (TEA)

Fuel Communications
Background: This study develops a novel water-based fracturing fluid to address challenges of high water consumption, poor thermal stability, and inadequate proppant transport in conventional hydraulic fracturing fluids.

Distribution Simulation of SC‐CO2 Carrying Proppants in Multicluster of Fractures Under Different Perforations

Energy Science &Engineering, Volume 13, Issue 10, Page 4853-4867, October 2025.
A physical model of multicluster fractures in horizontal well with perforation segments. ABSTRACT Supercritical carbon dioxide (SC‐CO2) fracturing is a new type of waterless staged multicluster fracturing. Different from one single fracture, the slurry almost simultaneously flows to multiple fractures in staged multicluster fracturing, resulting in a ...

Evolution of Friction and Permeability in a Propped Fracture under Shear

Geofluids, 2017
We explore the evolution of friction and permeability of a propped fracture under shear. We examine the effects of normal stress, proppant thickness, proppant size, and fracture wall texture on the frictional and transport response of proppant packs ...

Limits of Self‐Propping in Enhanced Geothermal Systems: New Experimental Insights From Shear, Tensile and Saw‐Cut Fractures in Odenwald Granodiorite

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Enhanced Geothermal Systems (EGS) use engineered fracture networks as fluid pathways and heat exchangers in hot, low‐permeability rock. Unlike gel‐proppant hydraulic fracturing treatments, many EGS use hydraulic shear stimulation to increase fracture permeability by self‐propping displaced rough surfaces of hard‐rock fractures caused by ...

Modelling the adsorption-desorption behavior of CO2 in shales for permanent storage of CO2 and enhanced hydrocarbon extraction [PDF]

, 2017
Increasing global need for energy security has spurred a need for enhanced oil and gas recovery from unconventional reservoirs. From a carbon cycle point of view however, enhanced hydrocarbon extraction results in higher concentrations of CO 2 in the ...

Imaging Proppant in a Shallow Hydraulic Fracture Using Ground‐Penetrating Radar

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract Hydraulic fracturing has been used to enhance the oil and gas recovery and facilitate remediation of groundwater contaminants, particularly in low‐permeability materials such as shales. Fracture geometry can impact the success of these applications, but techniques for imaging how hydraulic fractures grow under different conditions remains ...

Study on Proppant Transport among the Perforations within a Cluster and Accumulation in Inclined Wellbores Considering Turbulence Effect [PDF]

Lithosphere
During hydraulic fracturing, the uniform distribution of proppant among perforations is crucial for enhancing reservoir permeability. However, problems such as uneven proppant distribution between perforations and accumulation-induced blockage often ...

Experimental Study of Sand Distribution among Perforation Clusters in Horizontal Wellbore of Shale Gas Reservoir

Journal of Chemistry, 2020
Multistage horizontal fracturing is the key technique in developing shale gas reservoirs. In each stage, several perforation clusters will be placed to create complex fractures, and the parameters of perforation clusters are almost the same, so the ...
