PROPPANT FLOW AND TRANSPORT MODELING IN DEFORMABLE HYDRAULIC FRACTURE NETWORKS [PDF]
, 2018 The objective of the hydraulic fracturing stimulation is to create a large volume of fractured rock with enhanced permeability. The effectiveness of a hydraulic fracturing stimulation depends on maintaining the created fractures permeable so that ...

Proppant transport in secondary Sand fracturing using Eulerian-Eulerian multiphase model Approach [PDF]
Secondary sand fracturing, an innovative hydraulic fracturing technique, divides the injection of proppant into two stages, altering the reservoir's rock mechanics and fracturing fluid flow paths, thus effectively controlling fracture creation and ...

Deep Underground Science and Engineering, EarlyView.This study establishes a multi‐factor coupling framework for predicting breakdown pressure in laminated shale by integrating experimental hydraulic fracturing tests, physics‐informed neural networks (PINNs), and Sobol sensitivity analysis. It reveals how differential stress, the bedding dip angle, and the injection rate interact to influence fracture ...

Modeling proppant transport and settling in a 3D propagating fracture
Deep Underground Science and Engineering, EarlyView.A versatile multiphysics tool is presented for simulating the complex processes involved in hydraulic fracturing treatments. The model couples fracture opening and propagation, variable‐density slurry flow, and proppant particle transport within the multiphysics object‐oriented simulation environment framework, based on two‐phase mixture equations and ...

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 11, Page 4518-4540, 10 August 2026.ABSTRACT Numerical simulation of hydraulic fracturing remains challenging due to the strong coupling between geomechanics and fluid flow when modelling multiple physical mechanisms of rock deformation, fracture evolution and fluid leak‐off. This study develops a coupled hydraulic fracture propagation framework that combines the extended finite element ...

Nordgren PINNs to VQE: Advancing Hydraulic Fracturing Simulations in Shale Reservoirs
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 12, Page 4863-4878, 25 August 2026.ABSTRACT This study advances hydraulic fracturing simulations in shale reservoirs using two computational paradigms, Physics‐Informed Neural Networks (PINNs) and the Variational Quantum Eigensolver (VQE). PINNs were employed to solve Nordgren's equation, which governs fracture width evolution, by embedding physical laws into the neural network ...

A method of proppant pack permeability assessment [PDF]
, 2015 Hydraulic fracturing methods used for low permeability reservoirs such as shale gas or tight gas require the use of proppants. The current standard used for proppant assessment does not take into account its interaction with the rock and the embedment ...

The price responsiveness of shale producers: Evidence from micro data
Quantitative Economics, Volume 17, Issue 2, Page 394-430, May 2026.We show that U.S. shale oil producers exhibit a high degree of short‐run price responsiveness, primarily through the timing of well completions and refracturing. Using a novel monthly well‐level panel covering over 120,000 shale wells across ten states from 2005 to 2019, we document significant supply adjustments to price signals.
