Retention of Hydraulic Fracturing Water in Shale: The Influence of Anionic Surfactant
Retention of Hydraulic Fracturing Water in Shale: The Influence of Anionic Surfactant However, the role of some surface active agents like surfactants that are added in the hydraulic fracturing mixture in this issue needs to be understood. In this study, the influence of Internal Olefin Sulfate (IOS), which is an anionic
Improved Water Use Estimates for Drilling and Hydrualic Fracturing in Northeastern Colorado
This study shows that the number of hydraulic fracturing stages is a better measure of the future water demands for horizontal wells. Vertical wells use significantly less water than horizontal wells and will be less prevalent in the future. Introduction Water resources in Northeastern Colorado and the western United States are constantly
Evaluation of Microseismicity Related to Hydraulic Fracking Operations of Petroleum Reservoirs and Its Possible Environmental Repercussions
In addition, the relationship between microseismic magnitude and both depth and injection parameters is examined to delineate the possible framework that controls the system. Generally, microseismicity of typical hydraulic fracturing and injection operations is relatively similar in the majority of basins under investigation and the overall associating seismic energy is
A Comprehensive Prediction Model of Hydraulic Extended-Reach Limit Considering the Allowable Range of Drilling Fluid Flow Rate in Horizontal Drilling
Results show that when Qmin ≤Qr ≤Qmax (Case I), Lh depends both on horizontal-section limit based on rated pump pressure (Lh1 ) and horizontal-section limit based on rated pump power (Lh2 ); when Qmin < Q max < Qr (Case II), Lh is exclusively controlled by Lh1; while Lh is only determined by
