ACSL4‐Dependent Lysosomal Lipid Peroxidation Links WTAP‐Mediated m6A Modification to Intervertebral Disc Degeneration

Advanced Science, EarlyView.
IL‐1β upregulates the protein level of WTAP, which promotes the m6A modification of ACSL4 mRNA in an IGF2BP2‐dependent manner, thereby enhancing its stability. The increased ACSL4 drives lipid peroxidation, leading to lysosomal membrane permeabilization (LMP) and impaired mitophagy, which collectively accelerate intervertebral disc degeneration (IVDD).

Fracturing Fluids and Fracturing Fluid Additives

2018
Fracturing is one of the measures to increase production and injection by cracking the formation with high pressure. The cracks are then supported by proppants to reduce the flow resistance. The major contents of this chapter are fracturing fluids and fracturing fluid additives.

Role of overpressurized fluid and fluid-driven fractures in forming fracture networks

Journal of Geochemical Exploration, 2014
Abstract A 2-D numerical study was carried out, using a fully coupled rock deformation and fluid flow hydraulic fracturing model on fracture network formation in a low-permeability naturally fractured rock, in which new fractures are allowed to nucleate and grow driven by overpressurized fluid.

Effect of Fracturing Fluids on Fracture Conductivity

Journal of Petroleum Technology, 1975
Several types of fracturing fluids were tested for potential adverse effects on fracture conductivity. A predictive method based on the volume of residue in a fluid after it degrades was developed that describes the local effect of fluid residue on fracture conductivity. Introduction Fracturing fluids

Dynamic Fluid Loss of Fracturing Fluids

SPE Annual Technical Conference and Exhibition, 1983
ABSTRACT The relationship between rheology and fluid loss and the effects of shear history, temperature, cross-linker and fluid-loss additive on fluid loss of hydroxypropyl guar gels are discussed. Tests were performed under dynamic conditions using an apparatus which incorporates in-line mixing of crosslinked fluids, so that fluids ...

Fracturing Fluids - Then and Now

Journal of Petroleum Technology, 1996
Summary Fracturing fluid provides the means by which the hydraulic fracturing process can take place. All applications of well stimulation by fracturing must include selection of fracturing fluid in the initial phases of fracture design and treatment planning.

Modeling Fracture Fluid Cleanup in Hydraulic Fractures

SPE Annual Technical Conference and Exhibition, 2002
Abstract The retention of fracturing fluid in a proppant pack reduces the dimensionless fracture conductivity, Fcd, resulting in poor well productivity regardless of fluid type (gelled oil, crosslinked polymers, viscoelastic surfactants, or foams).
