| 1 | Replacement of annular domain with trapezoidal domain in computational modeling of nonaqueous-phase-liquid dissolution-front propagation problems显示文摘In order to simulate the instability phenomenon of a nonaqueous phase liquid(NAPL) dissolution front in a computational model, the intrinsic characteristic length is commonly used to determine the length scale at which the instability of the NAPL dissolution front can be initiated. This will require a huge number of finite elements if a whole NAPL dissolution system is simulated in the computational model. Even though modern supercomputers might be used to tackle this kind of NAPL dissolution problem, it can become prohibitive for commonly-used personal computers to do so. The main purpose of this work is to investigate whether or not the whole NAPL dissolution system of an annular domain can be replaced by a trapezoidal domain, so as to greatly reduce the requirements for computer efforts. The related simulation results have demonstrated that when the NAPL dissolution system under consideration is in a subcritical state, if the dissolution pattern around the entrance of an annulus domain is of interest, then a trapezoidal domain cannot be used to replace an annular domain in the computational simulation of the NAPL dissolution system.However, if the dissolution pattern away from the vicinity of the entrance of an annulus domain is of interest, then a trapezoidal domain can be used to replace an annular domain in the computational simulation of the NAPL dissolution system. When the NAPL dissolution system under consideration is in a supercritical state, a trapezoidal domain cannot be used to replace an annular domain in the computational simulation of the NAPL dissolution system. | 赵崇斌 Thomas POULET Klaus REGENAUER-LIEB | 2015 | Journal of Central South University2015，22，5： | 2 |
| 2 | Coupling of Thermal-Hydraulic-Mechanical Processes for Geothermal Reservoir Modelling显示文摘This paper uses a fully coupled framework of thermal-hydraulic-mechanical processes to investigate how the injection and extraction of fluid within a geothermal reservoir impacts on the distributions of temperature,pore pressure,and deformation within the rock formations. Based on this formulation,a numerical model is developed in light of the thermodynamics of porous materials. The proposed procedure relies on the derivation of dissipative flow rules by postulating proper storage and dissipation functions. This approach opens new horizons for several resource engineering applications. Since it allows for full coupling,this formulation can play a key role in predicting risks when used for reservoir simulation. The results indicate that the injection-extraction process and temperature change have a definite impact on altering the in-situ properties of the reservoir. | Ali Karrechl Oussama Beltaief Ruyan Vincec Thomas Poulet Klaus Regenauer-Lieb | 2015 | Journal of Earth Science2015，26，1： | 1 |

| 4 | Deep Geothermal: The ‘Moon Landing' Mission in the Unconventional Energy and Minerals Space显示文摘Deep geothermal from the hot crystalline basement has remained an unsolved frontier for the geothermal industry for the past 30 years. This poses the challenge for developing a new unconventional geomechanics approach to stimulate such reservoirs. While a number of new unconventional brittle techniques are still available to improve stimulation on short time scales,the astonishing richness of failure modes of longer time scales in hot rocks has so far been overlooked. These failure modes represent a series of microscopic processes: brittle microfracturing prevails at low temperatures and fairly high deviatoric stresses,while upon increasing temperature and decreasing applied stress or longer time scales,the failure modes switch to transgranular and intergranular creep fractures. Accordingly,fluids play an active role and create their own pathways through facilitating shear localization by a process of time-dependent dissolution and precipitation creep,rather than being a passive constituent by simply following brittle fractures that are generated inside a shear zone caused by other localization mechanisms. We lay out a new theoretical approach for the design of new strategies to utilize,enhance and maintain the natural permeability in the deeper and hotter domain of geothermal reservoirs. The advantage of the approach is that,rather than engineering an entirely new EGS reservoir,we acknowledge a suite of creep-assisted geological processes that are driven by the current tectonic stress field. Such processes are particularly supported by higher temperatures potentially allowing in the future to target commercially viable combinations of temperatures and flow rates. | Klaus Regenauer-Lieb Andrew Bunger Hui Tong Chua Arcady Dyskin Florian Fusseis Oliver Gaede Rob Jeffrey Ali Karrech Thomas Kohl Jie Liu Vladimir Lyakhovsky Elena Pasternak Robert Podgorney Thomas Poulet Sheik Rahman Christoph Schrank Mike Trefry Manolis Veveakis Bisheng Wu David A.Yuen Florian Wellmann Xi Zhang | 2015 | Journal of Earth Science2015，26，1： | 0 |
