PT Version 2.80 - Pressure Transient Analysis Software
The PT software from the ComPort Computing Company puts the latest techniques for pressure transient analysis at your fingertips, at a price that is less than that of some of the latest spreadsheet or word processor packages. This advanced application implements interactive log-log type curve matching and classical techniques, as well as an advanced "Adjust and Compare" method which allows the user to interactively customize solutions to the well testing equations.
Some of the features of PT include:
Classical Cartesian, square-root and semi-log methods
Log-log type curves, with or without derivatives
Customized reservoir and well-models, including
Dual Porosity Reservoir
Dual Permeability Reservoir
Wellbore Mass Effects (i.e. Phase Redistribution)
Wellbore Fluid Momentum
General pseudo-pressures for real gas, ideal gas, and compressible oils
Non-linear search for automatic curve fitting of the well testing equations
Up to 1800 data points and 10 rate variations per test
Automatically uses superposition for multiple rates or optional use of "Equivalent Time"
Default US or SI units PLUS User Defined units in the data file
On-screen interactive graphics
Freeform data input from ASCII files
Presentation quality hard copy on most printers
Minimum system requirements are a PC-compatible computer with 640KB memory and VGA quality graphics. The use of an 80386SX or higher computer with a hard disk drive is recommended, as well as a dot matrix, ink jet or laser quality printer. Color and monochrome monitors are supported and a math-coprocessor will be used if available.
Purchase of PT includes software diskette, printed user's manual, free telephone support (voice or modem), as well as one FREE upgrade to a future revision of your choice. The price of PT is $350 direct from the ComPort Computing Company or $280 from SPE (SPE members only).
