The Effect of Slickwater on Shale Properties and Main Influencing Factors in Hydraulic Fracturing

open access: yesGeofluids, 2023
As shale gas reservoirs have low porosity and low permeability, hydraulic fracturing is a necessary means for industrial exploitation of shale gas. In this study, aiming at the problem of reservoir damage in the process of hydraulic fracturing of shale ...

Rapid and Slow Unlocking-Induced Startup Mechanisms of Locked Segment-Dominated Landslides

open access: yesGeofluids, 2023
Locked segment-dominated landslides initiate when locked segments are sufficiently damaged to be unlocked. The evolution of such slopes toward instability displays either an exponentially or stepwise accelerated displacement pattern, but the underlying ...

Preparation of Oil-Based Foam Gel with Nano-SiO2 as Foam Stabilizer and Evaluation of Its Performance as a Plugging Agent for Fractured Shale

open access: yesGeofluids, 2022
The development of natural fracture will lead to lost circulation, which will be likely to cause economic losses and reduce drilling efficiency. In order to solve this problem, an oil-based pressure-bearing foam gel plugging agent for fractured shale was

Source identification and risk analysis of potentially toxic elements (PTEs) in rainwater runoff from a manganese mine (south central Hunan, China)

open access: yesWater Supply, 2021
Potentially toxic elements (PTEs) in manganese ore areas are prevalent in rainwater runoff and pose a major threat to human health. In this study, field investigation and geostatistical analysis methods of positive matrix factorization (PMF) and ...

The Economics of Shale Gas Development [PDF]

open access: yesSSRN Electronic Journal, 2014
In the past decade, innovations in hydraulic fracturing and horizontal drilling have fueled a boom in the production of natural gas (as well as oil) from geological formations—primarily deep shales—in which hydrocarbon production was previously unprofitable. Impacts on US fossil fuel production and the US economy more broadly have been transformative,

A study of the mechanism of nonuniform production rate in shale gas based on nonradioactive gas tracer technology

open access: yesEnergy Science & Engineering, 2020
The performance of horizontal wells in shale gas is controlled by multiple factors, and there is a difference in gas production rate between different fracturing stages. However, the mechanism of the nonuniform gas production rate is still not clear.
