Type-Curve Models Available in PIE

The following is a summary of the type-curve models available in the PIE well-test analysis software. The models are grouped by 'type' with each type containing one or more related models. All of these models are computed by using a full analytic solution with the appropriate techniques (e.g. Laplace or Fourier transforms, Bessel functions, etc.). All models include well-bore storage and skin effects.

1) Homogeneous and Double-Porosity Reservoir

2) Hydraulic-Fracture

3) Layered Reservoir with No Reservoir Cross-flow


Multi-Layer, No Cross-Flow, Horizontal-Well

4) Layered Reservoir with Reservoir Cross-Flow

5) Partial-Penetration Well

6) Radial-Composite Reservoir
