Sufficient conditions for Hadamard well-posedness of a
coupled thermo-chemo-poroelastic system
Tetyana Malysheva, Luther W. White
Abstract:
This article addresses the well-posedness of a coupled parabolic-elliptic
system modeling fully coupled thermal, chemical, hydraulic, and mechanical
processes in porous formations that impact drilling and borehole stability.
The underlying thermo-chemo-poroelastic model is a system of time-dependent
parabolic equations describing thermal, solute, and fluid diffusions coupled
with Navier-type elliptic equations that attempt to capture the elastic
behavior of rock around a borehole. An existence and uniqueness theory for
a corresponding initial-boundary value problem is an open problem in the field.
We give sufficient conditions for the well-posedness in the sense of Hadamard
of a weak solution to a fully coupled parabolic-elliptic initial-boundary value
problem describing homogeneous and isotropic media.
