Numerical investigation of the correlations of hydraulic and elastic characteristics in diverse carbonate rock types

Deep Underground Science and Engineering, EarlyView.
We use the linear Boolean model and the discrete Fourier transformation approach to generate various carbonate rocks. The lattice Boltzmann method and the finite element method are applied to calculate permeability and elastic wave velocity, respectively.

Simple methods for assessing groundwater resources in low permeability areas of Africa [PDF]

, 2001
In many areas throughout Africa, a staggering proportion of wells and boreholes fail. Failure can occur for a number of reasons – inadequate maintenance and community involvement, poor engineering or a lack of water. Often it can be difficult to work

Leakage risk assessment system for salt cavern hydrogen storage

Deep Underground Science and Engineering, EarlyView.
Establishment of a leakage risk evaluation system for salt cavern hydrogen storage reservoirs using the entropy weight method plus two‐dimensional cloud modeling approach. Abstract Salt cavern hydrogen storage (SCHS) is an important component of large‐scale underground hydrogen storage, with advantages such as large hydrogen storage capacity and ...

Investigation of the failure characteristics of fissure tunnels under dynamic and static combinations

Deep Underground Science and Engineering, EarlyView.
This article aims to investigate the dynamic fracture response of fractured tunnel models under zero geological stress through physical experiments and numerical simulations. It further simulates the dynamic fracture characteristics of fractured tunnel models under geological stress ranging from 0 to 2.5 MPa using the numerical software AUTODYN ...

Development of an improved numerical model for fracture propagation in hydraulic fracturing of low-permeability formations using FracproPT software

Unconventional Resources
The primary technologies employed to access unconventional resources today are horizontal drilling and single or multi-stage fracturing. Micro-seismic data frequently corroborates that hydraulic fracturing in shale reservoirs generates intricate fracture
