ANALYZE is a history-matching program designed for pressure-transient analysis of well tests in single-phase, fluid-saturated reservoirs. Both interference tests and production tests can be analyzed to yield reservoir transmissivity (kh/..mu..), storativity (phi ch), and hydrologic boundaries. An analytic solution is used to calculate the pressure drawdown/buildup in an idealized reservoir system. A schematic of the basic reservoir/well model assumed by the computational algorithm is shown. The reservoir is assumed to be an isothermal, isotropic, homogeneous, porous medium of constant thickness and infinite areal extent. The production well is modeled as a line source which fully penetrates the reservoir. The flow into the well is radial and uniformly distributed over the height of the well (gravity effects neglected).
