Thesis (Ph.D.)--University of Minnesota, 1998.

This thesis is concerned with the modeling of some thermoporoelastic problems using singular solutions and with the design of a field experiment. It is shown that the theory of thermoporoelasticity can be successfully used to predict pore pressure and temperature induced by thermal loading. This class of thermoporoelastic problems can be modeled using "hybrid" sources that are combinations of heat, fluid and elastic singularities. Application of these sources allows determination of the large time response of the rock, which is often the practical case of interest.

520 $a This thesis is concerned with the modeling of some thermoporoelastic problems using singular solutions and with the design of a field experiment. It is shown that the theory of thermoporoelasticity can be successfully used to predict pore pressure and temperature induced by thermal loading. This class of thermoporoelastic problems can be modeled using "hybrid" sources that are combinations of heat, fluid and elastic singularities. Application of these sources allows determination of the large time response of the rock, which is often the practical case of interest.
520 $a The field experiment, which was designed and conducted to measure in-situ the most relevant thermoporoelastic constants, consists of two tests. The first one is an injection test to determine hydraulic properties of the rock. The second test is a heater test to determine thermal and hydro-thermal properties. In the injection test, a given volume of water was pumped quasi-instantaneously in a sealed-off interval (test zone) of the borehole; in the heater test, heat was produced at a constant rate while keeping the pore pressure in the test zone at a constant value. The tests were analyzed using several models with different degrees of complexity, from simple analytical models involving point or spherical sources to numerical simulations. Material properties were estimated by matching the time and the amplitude of the peak in the theoretical and experimental responses.
520 $a A model was proposed to predict the pore pressure and stress induced by heat generated by radioactive waste stored in a deep underground repository. The problem was analyzed using a semi-analytical approach based on thermoporoelastic heat source solutions considering both the case of a constant heat supply and the case of time-decaying heat (with exponential terms). The problem for a constant heat supply is solved analytically in closed form. The solution for a time-decaying heat supply is obtained using two different numerical schemes (one based on direct integration of convolution integrals and another one using the Laplace transform), which give virtually identical results.
