Transient modeling of host rock for a deep borehole nuclear waste repository
… A parametric study of input parameters such as rock permeability, borehole spacing, and pitch length, was performed to assess thermal behavior of the repository. Analysis of the results led to the conclusion that the water flow in the caprock is driven mostly by thermal expansion of water. The …

Using data analytics and laboratory experiments to advance the understanding of reservoir rock properties
… a shale formation has a tremendous impact on the permeability of the rock. The correlation between confining pressure and rock permeability is complicated and might be nonlinear. In this thesis, a series of laboratory tests was conducted on core samples extracted from four U.S. shale formations to …

Clay mineral formation and fluid-rock interaction in fractured crystalline rocks of the Rhine rift system : case studies from the Soultz-sous-Forêts granite (France) and the Schauenburg Fault (Germany)
… that occurred within both the buried basement rocks and similar exhumed units exposed in the uplifted rift shoulders. The rock alteration history is established largely on the basis of combined X-ray diffraction, X-ray textural goniometry, electron microscopy (SEM, HRTEM) and isotopic (K-Ar) …

Permeability Distribution Estimation Based on Semi-Analytical Reservoir Simulator
Estimation of rock permeability distribution can be realized by automatic history matching production data. The process of automatic history matching involves the minimization of an objective function which usually includes the sum of data mismatch part as well as the sum of prior model mismatch …

Magma emplacement and deformation in rhyolitic dykes : insight into magmatic outgassing
… dyke propagation were governed by the country rock permeability and strength, with pre-existing fractures playing a pivotal governing role. During this stage of dyke evolution significant amounts of exsolved gas may have escaped. Furthermore, during later magma emplacement within the dyke …

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 …

Geomechanical aspects of fracture growth in a poroelastic, chemically reactive environment
… 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 in a poroelastic media. A …

Modelling of fines migration mechanisms in high permeability sands: impact on reservoir performance.
… losses due to fines migrations in high permeability sandstone formations or sand packs. During drilling, production or injection, fines migration continues to cause formation impairment resulting in oil and gas inflow reductions or injectivity resistance. The problem is further enhanced …

QUANTIFICATION OF MELT DISTRIBUTION, MELT CONNECTIVITY, AND ANISOTROPIC PERMEABILITY OF DEFORMED PARTIALLY MOLTEN ROCKS USING X-RAY MICROTOMOGRAPHY
… km wide region of the mantle, from which partial rock ascends and erupts along narrow ridges that run along the middle of Earth’s oceans. Volcanic activity at mid-ocean ridges, the strength of Earth’s mantle, and the geochemical composition of volcanic rocks and ocean water are all influenced by …

THREE-DIMENSIONAL MODELING OF HYDRAULIC AND NATURAL FRACTURE INTERACTIONS AND ITS APPLICATIONS IN RESERVOIR STIMULATION
The ultralow permeability of the unconventional and geothermal reservoirs can be increased for economic production by hydraulic fracturing. Natural fractures and other discontinuities are inseparable elements of unconventional reservoir rock masses. During stimulation, hydraulic fractures often …

CO2-rock interaction during CO2-enriched brine injection into storage reservoirs using NMR integrated with fiber optic sensors
… the geo-mechanical strength of the reservoir rock, which could reactivate faults and lead to pathways for CO2 leakages. Rock strain is conventionally evaluated by linear variable differential transformers (LVDT) and electrical resistance strain gauges (ESG) that are attached to a rock sample’s …

Mobile NMR for rock porosity and permeability
… core-scanners were used to measure porosity and permeability of water-saturated drill cores and core plugs in a non-destructive way. In addition to their use in the laboratory, the small and light-weight devices are conveniently shipped, e.g. to drilling platforms. They allow rapid wellsite …

An experimental investigation of some capillary pressure-relative permeability correlations for sandstone reservoir rocks.
The water-oil relative permeability of the reservoir rock is one of the essential properties in petroleum engineering studies, and the use of this data is critical in the evaluation and management of oil fields, particularly in water flooding predictions and oil recovery calculations. The …
