Characterisation of the transmissivity field of a fractured and karstic aquifer, Southern France [PDF]

, 2015
International audienceGeological and hydrological data collected at the Terrieu experimental site north of Montpellier, in a confined carbonate aquifer indicates that both fracture clusters and a major bedding plane form the main flow paths of this ...

Petrogenetic and geochemical characteristics of some auriferous granitoids in the Kumasi Basin, Ghana: Implications for geodynamic settings and controls of orogenic gold mineralization in the Edikan Gold Mine

Deep Underground Science and Engineering, EarlyView.
The Fobinso granitoids are granodiorites, while the Esuajah granitoids are granites based on their mineralogical composition. The granitoids are generally enriched in LILE and LREE than HFSE, MREE, and HREE, indicating mixing with crustal sources during their evolution.

Study on Mine Earthquake Prediction Based on Numerical Simulation of Rock Fracture Evolution

Energy Science & Engineering
The deformation and instability of overlying strata is the root cause of roof dynamic disasters. Therefore, it is necessary to study the geomechanical behavior of overlying strata and the evolution law of three‐dimensional fracture morphology for ...

Determining the REV for Fracture Rock Mass Based on Seepage Theory

Geofluids, 2017
Seepage problems of the fractured rock mass have always been a heated topic within hydrogeology and engineering geology. The equivalent porous medium model method is the main method in the study of the seepage of the fractured rock mass and its ...

Characterizing groundwater flow and heat transport in fractured rock using Fiber-Optic Distributed Temperature Sensing [PDF]

, 2013
International audienceWe show how fully distributed space-time measurements with Fiber-Optic Distributed Temperature Sensing (FO-DTS) can be used to investigate groundwater flow and heat transport in fractured media.

Study on damage and failure characteristics of loaded gas‐bearing rock–coal–rock combination structures

Deep Underground Science and Engineering, EarlyView.
The influence of gas on the instability and failure of rock–coal–rock combinations is considered. The damage characteristics of gas‐bearing rock–coal–rock combinations under different confining pressures, axial loading rates, and gas are revealed. A constitutive model for gas‐bearing rock–coal–rock damage considering gas is established.

Optimal mud pressure design using nonlinear failure criteria for wellbores in shaley sedimentary reservoir

Deep Underground Science and Engineering, EarlyView.
The present study uses the Modified Mohr‐Coulomb true‐triaxial failure criterion (MMC_TT), which predicts the strength of rock better than the MGC criterion in laboratory true‐triaxial tests to overcome the limitations. Moreover, based on the data from previously published five vertical wells in the Krishna‐Godavari basin (K‐G basin), an empirical ...
