Geomechanical aspects of fracture growth in a poroelastic, chemically reactive environment
… growths are driven by fluid loading. The fluid flow properties of the host rock have a primary, but hitherto little appreciated control on the NHF propagation rates. This study focuses on investigating the impacts of host rock fluid flow on the propagation and pattern development of multiple NHF …

Lattice-Boltzmann modeling of multiphase flow through rough heterogeneously wet fractures
… often representing primary channels for fluid flow in low permeability rocks. While fracture surfaces are composed by different minerals and are rough by nature, mathematical models to predict flow properties rarely take in account these heterogeneities. Therefore, the pore-scale mechanisms of …

Geomechanical Reservoir Model Calibration and Uncertainty Assessment from Microseismic Data
Hydraulic stimulation of low permeability rocks in unconventional reservoirs has been observed to trigger microearthquakes (MEQs). Triggering of the MEQ events has been linked to the pore pressure, temperature, and in-situ stress variations which result in crack initiation. The resulting clouds of …

Factors influencing the mobility of uranium, thorium and rare earth elements at the Steenkampskraal monazite, North Western Cape
… as well as the ideal geology, which consists of low permeability rocks with groundwater flow governed by fractures. The ore body consists of a monazite [(REE, Th, U)P04], apatite [Ca₃P0₄)₂], chalcopyrite [CuFeS] and magnetite [FeP₄] veindeposit. Water was sampled from six boreholes in the …

LABORATORY-SCALE INVESTIGATION OF PERMEABILITY AND FLOW MODELING FOR HIGHLY STRESSED COALBED METHANE RESEROVIRS USING PULSE DECAY METHOD
The steady flow method (SFM), most commonly used for permeability measurement in the laboratory, is not applicable for tight rocks, higher rank coals and coals under highly stressed condition because of the difficulty in measuring steady-state gas flowrates resulting from the tight rock structure …

Digital Rock: Understanding the mechanism of Enhanced Oil Recovery (EOR) Core Floods
… phenomena was the detection of velocities lower than 10 ft d-1 using Magnetic Resonance Imaging (MRI). For that reason, an optimisation toolbox, which uses the relaxation times and the diffusion coefficients of the porous system as input and derives the optimum experimental parameters for …
