Abstract

Fault zones exhibit 3D variable thickness, a feature that remains inadequately explored, particularly with regard to the impact on fluid flow. Upon analyzing an analytic solution, we examine 3D thermal‐hydraulic (TH) dynamical models through a benchmark experiment, which incorporates a fault zone with thickness variations corresponding to realistic orders of magnitude. The findings emphasize an area of interest where vigorous convection drives fluid flow, resulting in a temperature increase to 150°C at a shallow depth of 2.7 km in the thickest sections of the fault zone. Moreover, by considering various tectonic regimes (compressional, extensional, and strike‐slip) within 3D thermal‐hydraulic‐mechanical (THM) models and comparing them to the benchmark experiment, we observe variations in fluid pressure induced by poroelastic forces acting on fluid flow within the area of interest. These tectonic‐induced pressure changes influence the thermal distribution of the region and the intensity of temperature anomalies. Outcomes of this study emphasize the impact of poroelasticity‐driven forces on transfer processes and highlight the importance of addressing fault geometry as a crucial parameter in future investigations of fluid flow in fractured systems. Such research has relevant applications in geothermal energy, CO2 storage, and mineral deposits. Plain Language Summary: Exploring critical parameters affecting the fluid flow within fault zones in the Earth's crust is of fundamental scientific and economic interest. Among them, fault zone thickness and tectonic regimes are two parameters whose role remains unexplored. The results of this study show that fluid flow by convection is vigorous in the zone where fault thickness is largest. In this area of interest, the tectonic regimes impact convective dynamics and modify the thermal distribution of the system. These generic outcomes are discussed in relation to real‐cases scenarios and emphasize the fundamental role of considering a Geometric parameter (G), the fault zone thickness variation, as well as tectonic regimes, during the exploratory phase for geothermal energy, CO2 storage, and mineral exploration. Key Points: Based on a critical Rayleigh number analysis and 3D numerical modeling, we explore the effects of fault zone thickness variations on fluid flowIn line with the critical Rayleigh number analysis, our numerical results reveal that thermal convection is more efficient in areas where the fault zone thickness is largestThe poroelasticity‐driven force alters the convective dynamics within the zone of interest in the fault zone (i.e., the thickest part) [ABSTRACT FROM AUTHOR]

17. Evidence for a transient hydromechanical and frictional faulting response during the 2011 Mw5.6 Prague, Oklahoma earthquake sequence

Author

Norbeck, J. H. and Horne, R. N.

Abstract

Mechanisms for the delayed triggering between the Mw4.8 foreshock and Mw5.6 main shock of the 2011 earthquake sequence near Prague, Oklahoma, USA, were investigated using a coupled fluid flow and fault mechanics numerical model. Because the stress orientations, stress magnitudes, fault geometry, and earthquake source mechanisms at the Prague site have been well characterized by previous studies, this particular earthquake sequence offered an opportunity to explore the range of physical processes and in situ fault properties that might be consistent with the 20 h delayed triggering effect observed at the site. Our numerical experiments suggest that an initial undrained response resulting from elastic stress transfer from the foreshock followed by transient fluid flow along the fault may have contributed to the earthquake nucleation process. The results of the numerical experiments were used to constrain fault compliance and fault transmissivity for the fault that hosted the Mw5.6 event. Relatively compliant behavior in response to changes in normal stress, corresponding to Skempton pore pressure coefficients near 1, was consistent with the field observations. Fault transmissivity was estimated to range from 10−18to 10−15m3. This study has implications for understanding hydraulic properties, frictional properties, and faulting behavior of basement faults in Oklahoma that are large enough to host damaging earthquakes. The 2011 Prague, Oklahoma, earthquake sequence was modeled using a fully coupled fluid flow and rate‐and‐state earthquake modelThe delay between the foreshock and the main shock may have been influenced by an undrained response followed by fluid flow along the faultEstimates of in situ transmissivity and compliance were obtained for the large basement fault that hosted the main shock

28. Numerical Modeling of a Desaturating Geothermal Reservoir

Author

Horne, R. N. and O'sullivan, M. J.

Abstract

To achieve a better understanding of hot-water geothermal reservoirs, the problem of a hypothetical geothermal aquifer that depletes the fluid saturating its upper regions during production is considered. This depletion leads to the characteristic depressurization and drawdown of the liquid surface observed typically at the Wairakei geothermal field in New Zealand. This effect is significant in that the subsequent appearance of a horizontal pressure gradient may cause premature shutdown of the bore field because of the encroachment of colder groundwater.In fact, the results of the modeling show a different behavior, emphasizing the vertical movement of the saturating hot fluid as a more important effect. The model gives an indication of the time the reservoir will take to reach pressure equilibrium, and its output at that time.Problems associated with the numerical procedures are considerable even though the model is single-phase and axisymmetric, and the value of such an intricate numerical model is tenuous. By using a simpler model, replacing the moving surface by an encroaching region of cold water, it is possible to obtain a lower bound for the useful life of the system and also to examine the possible effects of recharging the system.

29. Natural Convection in a Multi-Layered Geothermal Reservoir

Author

Rana, R., Horne, R. N., and Cheng, P.

Abstract

The effect of layered structure of rock formation on free convection in a geothermal reservoir is investigated in this work. The model examined is that of a rectangular reservoir comprised of three horizontal permeable layers with different permeabilities. The reservoir is considered to be bounded by impermeable surfaces on the sides and at the bottom. The upper boundary of the aquifer is permeable, which permits the recharge and discharge of water to and from the aquifer. A transient two-dimensional convective flow is developed when the impermeable boundaries are raised suddenly to high temperatures. The governing nonlinear partial differential equations with appropriate boundary and initial conditions are solved numerically by finite difference methods. Application of the direct method for solving Poisson’s equation for stream function made it possible to carry out the solution for a much longer time than possible with iterative techniques. Numerical results are obtained for various parameters and configurations of the geothermal reservoir. The influence of a less permeable middle layer on the flow and heat transfer characteristics in the aquifer is discussed. The computed vertical temperature profiles are similar in shape to the complex temperature profiles observed at the HGP-A well.

31. Convection in a Porous Medium Heated from Below: The Effect of Temperature Dependent Viscosity and Thermal Expansion Coefficient

Author

Horne, R. N. and O’Sullivan, M. J.

Abstract

The natural convection of water through permeable formations is an important phenomenon governing the behavior of geothermal aquifers. In such situations the temperature of the fluid can vary by amounts of the order of 250 K, over which range the viscosity of the water may decrease by as much as a factor of 10, and the coefficient of thermal expansion may increase by an even greater factor. Although previous studies have examined the effect of this behavior on the onset conditions at which natural convective flow in the medium first occurs, the actual flow patterns that will result from the convection of a fluid with such widely varying properties has not been reported. To this end, numerical methods of solution are applied to this problem and a visualization of the flows obtained. By solving in terms of both pressure and stream function instead of stream function alone, it was possible to maintain semiconservative properties of the numerical scheme. The convective motion is unstable (in two dimensions) at even moderate values of the Rayleigh number and exhibits a fluctuating convective state analogous to the case of a fluid with constant viscosity and coefficient of thermal expansion. In some cases the acceleration of the flow in certain areas due to the decrease in viscosity causes localized thermal instabilities.
