This paper consists of three parts. The first part presents new type curves for a well intercepting a vertical fracture with finite conductivity. The type curves are for a well located in a limited reservoir and producing under constant flowing pressure. The second part describes how the type curves can be used in predicting and matching reservoir performance. Description of automated history match is also included. The match procedure considers the effect of turbulent flow inside the fracture as well as the change in fracture conductivity due to change in flowing pressure (crushing of sand).

The third part of the paper presents application of the first two parts to actual field cases. The discussed procedure is applied to two gas wells in South Texas. The paper presents the following for each well:

  1. A pre-fracturing build-up test analysis.

  2. Fracturing treatment design.

  3. History match of production data calculating the fracture length and conductivity.
