The Issue

Development planners add big value to the E&P decision process when they can spend the majority of their time on scenario evaluation and insight generation. We often see that due to the limitations of other tools and workflows, the opposite is true, and most of a planner’s time is spent on modeling and data manipulation with little time left for value-added analysis.

The PetroVR Solution

Figure 1: Scenario Tree provides a quick view of all scenarios and contains all deterministic and stochastic results for scenarios

PetroVR addresses this with robust, easy to use tools that get the development planner quickly into insight generation where value can be added, while minimizing the time spent modeling.

The scenario evaluation capabilities built into PetroVR allow the user to focus on insights rather than on data and plot generation. Scenarios take advantage of the PetroVR change system to automatically track and display all changes made to a scenario thereby eliminating the need for detailed manual record keeping.

How It Works

All scenarios are accessible in a single interface. That interface contains the full deterministic and stochastic results for each scenario.

It also provides unified displays of both deterministic and stochastic results for all scenarios. The graphical interface for comparing scenario results include plots of deterministic single-value and array results.

Stochastic “s-curves” for single value results and “percentile” and “box-plots” for array results are available once a Monte Carlo simulation has been performed on the scenarios.

In addition, the cross-plot capability for multiple scenarios can help identify the cross-over point where one scenario indicates the preferred alternative. For example, as shown below, a “stand-alone” strategy is generally superior to a “tie-back” strategy when the reserves exceed 600 MMbbl.

The Results

“PetroVR Scenarios get us into insight generation more quickly, where value can be added, while minimizing time on routine modeling.”
