Abstract
— This paper draws on the simulation of hydraulic fracturing
processes combining a model for fluid flow in the fracture with Blot's' model
of coupled poroelasticity for the rock behavior. The theoretical background
for the computational implementation is discussed.
INTRODUCTION
The strategy for the simulation of hydraulic fracturing consists basically in a
model that considers the variation of fracture opening as a function of the
fracture pressure distribution, taking into account poroelastic^ behavior of the
rock. On the other hand, the fracture pressure distribution is obtained based
on the assumption of a flow regime of a Newtonian fluid between two
parallel plates. This paper describes the theoretical background for the
computational
