A numerical investigation on the performance of hydraulic fracturing in naturally fractured gas reservoirs based on stimulated rock volume

Journal of Petroleum Exploration and Production Technology, 2020
All reservoirs are fractured to some degree. Depending on the density, dimension, orientation and the cementation of natural fractures and the location where the hydraulic fracturing is done, preexisting natural fractures can impact hydraulic fracture ...

Simulation of hydraulic fracture initiation and propagation for glutenite formations based on discrete element method

Frontiers in Earth Science, 2023
The existence of gravels in the glutenite formations leads to the complex geometries of hydraulic fracturing propagation and difficult construction in fracturing engineering. To study the hydraulic fracturing propagation law of glutenite formations, this

Interference fracturing: Nonuniform distributions of perforation clusters that promote simultaneous growth of multiple hydraulic fractures [PDF]

, 2015
One of the important hurdles in horizontal-well stimulation is the generation of hydraulic fractures (HFs) from all perforation clusters within a given stage, despite the challenges posed by stress shadowing and reservoir variability.

A criterion for identifying hydraulic fractures crossing natural fractures in 3D space

Petroleum Exploration and Development, 2014
Based on the analysis of the stress fields near the hydraulic fracture tip and on the natural fracture surface, a criterion for identifying hydraulic fractures crossing natural fractures was proposed. A series of hydraulic fracturing tests were conducted

Investigation of the Hydraulic Fracture Propagation Law of Layered Rock Strata Using the Discrete-Particle Model

Geofluids, 2022
Hydraulic fracturing is a rock structure transformation method that significantly weakens the mechanical properties of the hard roof strata. Considering the poor hydraulic fracturing effect of special structure such as composite layered rock, this paper ...

General criterion for intersection between hydraulic induced fractures and pre-existing natural fractures

Petroleum, 2019
Pre-existing natural fractures and other structurally weak planes are usually well-developed in unconventional reservoirs. When such fractures intersect with hydraulic induced fractures, they will redirect and propagate as an important mechanical ...
