摘要：

This paper reports the progress in the development of axisymmetric/plane strain hydraulic fracturing models based on the Biot theory of poroelasticity. Integral formulae coupling fracture opening displacement (or aperture) with the fluid pressure and leakage along fracture wells are derived. They are analogous to the Sneddon integral formula for linear elastic fracture. The analysis is based on the formalism of the theory of analytic/generalized analytic functions. The exact solution for the axisymmetric steady-state ''ideal fracture'' is obtained.
