UFM‐Based Simulation of Competitive Multi‐Fracture Propagation in Horizontal Wells
Simulation schematic of Competitive Multi‐Fracture Propagation in Horizontal Wells. ABSTRACT Multi‐stage hydraulic fracturing in horizontal wells is vital for stimulating unconventional reservoirs, yet uneven fracture propagation often restricts the effective communication volume of the reservoir.

ABSTRACT Although the conversion of end‐of‐lifetime fractured hydrocarbon wells to geothermal wells has gained a strong momentum in research, it is necessary to perform thorough technical assessments of well conversion before pilot testing. The objective of the study was to perform such an assessment on converting fractured horizontal hydrocarbon wells

Experimental study on the self-suspending proppant-laden flow in a single fracture
The flow of proppant-laden fluid (PLF) in the fracture is a typical problem of solid-liquid two phase flow, and the transportation and deposition of proppants are essential to determine the flow conductivity of hydraulic fracturing.

ABSTRACT We compare two algorithms to simulate the propagation, arrest, recession, and closure of a planar hydraulic fracture, focusing on their ability to capture the physical processes governing fracture recession and closure. The first algorithm is based on a fixed grid with contact detection during recession, while the second is based on a moving ...

Hydraulic fracturing is a conventional practice for production enhancement in low production and damaged wells. Proppant flowback has been a concern in hydraulic fracturing since proppant began to be used as fracture supporting material.

Water hydraulic fracturing involves pumping low viscosity fluid and proppant mixture into the artificial fracture under a high pumping rate. In that high Reynolds number conditions (HRNCs, Re > 2000), the turbulence effect is one of the key factors ...

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 ...

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