Petroleum decision software

Project inputs change constantly. Your outputs should too.

Change an assumption and EVALUATE recalculates the project economics. Fiscal logic, sources and uncertainty stay attached to the result.

Product surfaces use representative project data — Marlin Deep, r0 base case.

EVALUATE is the economic foundation. STAGE connects delivery and CAPITAL funding.

Scenario comparison

Revise the project without rebuilding the model.

The same calculation logic carries through each case, and the bridge decomposes the resulting NPV movement by cash-flow effect.

EVALUATE building a before-and-after NPV bridge from the base case to the higher-price variant

Evidence + uncertainty

From assumptions to traceable results.

Every result keeps its assumptions, fiscal source, scenario and calculation version. Uncertainty is carried as a distribution, not a single point.

01

Recalculate

Move an assumption and the economics move with it. Nothing gets rebuilt.

02

Trace the result

Any number traces back to the input, the fiscal interpretation and the case that produced it.

03

Quantify uncertainty

Results come out as distributions, so the downside is quantified rather than inferred.
