This paper presents a mathematical model to describe the pressure behavior for infinite conductivity horizontal wells in naturally fractured formations. A double-porosity medium with pseudo-steady state interporosity flow is considered.

The general method of extending solutions for homogeneous reservoirs to double-porosity models is used. Wellbore storage and skin effects are included by applying the Laplace transformation to the superposition equation. This is also a general and simple method.

Methods of well testing analysis are examined, such as conventional and type-curve matching techniques.
