WellTest™ pressure transient analysis software

Interpret pressure response and evaluate well performance

WellTest™ pressure transient analysis software provides tools enabling interpretation of pressure and rate behavior, well test design, evaluation of reservoir and completion response, and deliverability forecasting. Guided data-entry workflows support consistent preparation of test information.

It covers conventional drawdown, buildup, injection, falloff, and multi-rate tests, as well as selected unconventional workflows.

Analyze tests, forecast deliverability and history-match well behavior

• Analyze pressure-transient tests: Interpret drawdown, buildup, injection, falloff, and multi-rate tests for oil, gas, or water wells.
• Evaluate unconventional tests: Review pressure behavior after perforating or mini-frac operations using applicable analysis methods.
• Design and simulate tests: Plan test duration and operating sequences and examine whether a proposed test can answer the intended reservoir question.
• Forecast deliverability: Build inflow and outflow relationships and compare stimulation or compression scenarios.
• History-match well behavior: Use analytical or numerical models to compare observed pressure and rate behavior with modeled response.

Interpret tests, assess scenarios, and choose the appropriate modeling method

• Structured analysis: Use guided inputs and established diagnostic workflows to organize pressure, rate, fluid, and completion information.
• Broader test coverage: Apply a single analysis environment to multiple test types and well configurations, subject to licensed models.
• Forward-looking decisions: Move beyond interpretation to test design, deliverability estimates, and what-if operating scenarios.
• Model choice: Use analytical or numerical history matching according to the reservoir and completion complexity.

Analyze pressure behavior, forecast deliverability, and model well behavior

• Guided data preparation: Use structured entry workflows for test, well, fluid, and rate information.
• Conventional pressure-transient analysis: Analyze drawdown, buildup, injection, falloff, and multi-rate tests for vertical or horizontal wells.
• Unconventional workflows: Evaluate selected pressure-buildup and mini-frac falloff scenarios.
• Deliverability and test design: Estimate deliverability, compare operating scenarios, and simulate planned tests.
• Analytical and numerical history matching: Model complex well behavior, including multi-fractured wells, using supported analytical or numerical methods.
• Fluid models: Apply supported black-oil, volatile-oil, and rich-gas-condensate numerical representations where appropriate.
