We developed a model for fracture production produced during detonation of an explosive mixture in a 10m packed off section of a shallow borehole. The model is based upon an actual field and lab experiments on low-damage borehole fracturing performed at Sandia National Labs by Mark Grubelich in 2014. The simulation was developed by O. Vorobiev at LLNL.

A schematic of stratigraphic column of the marcellus shale with basic information about the fracking process. It is simple, but good reference for people who are new to hydraulic fracturing technology and research.
Sitecontains over 1,200 sources on natural gas extraction by hydraulic fracturing focusing on the Marcellus and Utica shales. The catalogueincludes research and documentscentered on tourism,crime, social services usage, housing development, road quality, urban planning, populationconcerns, as well as many other social issues.
Low permeability geothermal reservoirs can be stimulated by hydraulic fracturing to create Enhanced (or Engineered) Geothermal Systems (EGS) with higher permeability and improved heat transfer to increase heat production. In this paper, we document our effort to develop a numerical simulator with explicit geomechanics-discrete flow network coupling by utilizing and further advancing the simulation capabilities of the Livermore Distinct Element Code (LDEC). The important modules of the simulator include an explicit finite element solid solver, a finite volume method flow solver, a joint model using the combined FEM-DEM capability of LDEC, and an adaptive remeshing module. The numerical implementation is verified against the classical KGD model. The interaction between two fractures with simple geometry and the stimulation of a relatively complex existing fracture network under different in-situ stress conditions are studied with the simulator.
This dataset includes files used to fit planar fractures through the preliminary earthquake catalogs of the three stages of the April 2022 well 16A(78)-32 stimulation which is linked bellow. These planar features have been used to update the FORGE reference Discrete Fracture Network (DFN) model. The files are provided to encourage other modelers to use additional workflows to find additional/alternative features. To this end, the dataset includes the cleaned earthquake catalog data translated to the FORGE reference model global reference frame, the well trajectory of 16A(78)-32 in those same coordinates, the fit 15 planar features in csv format, and a pdf file with slides illustrating the process used to fit the features. A recorded presentation of this material is available from the October 2022 FORGE Modeling and Simulation Forum which is also linked below.
