Main Features

Interoperability with FAST RTA

Production data, reservoir and fluid properties contained within F.A.S.T. RTA™ or F.A.S.T. WellTest™ can be accessed by simply opening a file created by either program.

Multi-Layer Model

Considers “unequal” initial layer pressures, deals with crossflow during pre-flow, drawdown and build-up periods, honours material balance by calculating individual pseudo-time for each reservoir layer, and accounts for hydrostatic pressure differences.

Anisotropic Model for Vertical Wells

Solves for horizontal permeability (kx, ky) in fully penetrating vertical wells and vertical permeability (kz) in partially penetrating vertical wells.

Closed Chamber Test Analysis

Based on PITA theory, it considers “instantaneous” decrease in wellbore storage to accommodate the effect of down-hole shut-in during drillstem tests and perforation inflow tests.

Material Balance Pseudo-Time for Dry CBM Reservoirs

Incorporates desorption compressibility in the total system compressibility. It has been implemented to allow access to all existing diagnostic analysis and models.

Quick & Easy Data Entry

A comprehensive system of wizards is available to guide the user through the appropriate steps to ensure data is entered properly and that a reliable analysis is obtained.

Pressure Transient Analysis

Conventional: Analyze drawdown/build-up data or injection/fall-off data for gas, oil and water wells. Use both vertical and horizontal well configurations.
Unconventional: Analyze pressure buildup after perforating, or analyze pressure falloff following frac calibration tests.

Analytical Modeling

Create reservoir conditions from a host of analytical models to match the pressure behaviour observed during a test, or during extended production/injection periods.

Deliverability Forecasting

Predict the deliverability of a well based on modeling results. Generate "what-if" scenarios to determine the increase in deliverability expected from stimulation or adding compression.

Test Design

Simulate a test to determine optimal test procedure. Determine if a horizontal well should be considered as an alternative to a vertical well.

Other

Analyze results from multi-rate tests to determine the components of the total skin factor. Establish IPR and OPR based on test results.
