Adsorption damage and control measures of slick-water fracturing fluid in shale reservoirs

Coupled Thermo-Hydro-Mechanical-Chemical Modeling of Water Leak-Off Process during Hydraulic Fracturing in Shale Gas Reservoirs

The water leak-off during hydraulic fracturing in shale gas reservoirs is a complicated transport behavior involving thermal (T), hydrodynamic (H), mechanical (M) and chemical (C) processes. Although many leak-off models have been published, none of the models fully coupled the transient fluid flow modeling with heat transfer, chemical-potential equilibrium and natural-fracture dilation phenome...

Characteristics of Shale Gas Reservoir in Jiyang Depression and its Significance in Drilling and Exploitation

Physical and geochemical characteristics of shale play conclusive role in confirming operation measures during drilling and stimulation. The properties of shale samples from Jiyang depression were investigated through X-ray diffraction, scanning electron microscope, adsorption isothermal, high pressure mercury intrusion, methylene blue trihydrate, pressure pulse decay, tests of specific water w...

Source and fate of hydraulic fracturing water in the Barnett Shale: a historical perspective.

Considerable controversy continues about water availability for and potential impacts of hydraulic fracturing (HF) of hydrocarbon assets on water resources. Our objective was to quantify HF water volume in terms of source, reuse, and disposal, using the Barnett Shale in Texas as a case study. Data were obtained from commercial and state databases, river authorities, groundwater conservation dis...

Coupled 3-D numerical simulation of proppant distribution and hydraulic fracturing performance optimization in Marcellus shale reservoirs

Hydraulic Fracturing of Naturally Fractured Reservoirs

A carefully engineered stimulation that makes use of opening mode fractures is an effective way to reduce injection and production impedance and provide better access for the fluid to enter and promote shearing in the main reservoir volume. We present results from field experiments that mapped the fracture geometry for opening mode hydraulic fractures formed in naturally fractured crystalline r...
