Advanced Model: Hybrid

The hybrid model is similar to the analytical gas enhanced fracture region model. It also models single-phase flow (gas + immobile water) and the well completion configuration, and the reservoir is similar to the ones in the Enhanced Fracture Region Model.

Performing an analysis using a Hybrid Model is very similar to performing an analysis using an analytical model. However, the calculations used by the hybrid model are more rigorous, as they accurately account for changes in gas properties. To view the calculations used in the hybrid model, see Hybrid Model Theory.

Prerequisites

Before you start modeling reservoirs, ensure that you have all the required information in your WellTest project:

• Well production data (rates and sandface pressures) must be populated in the Production Editor tab
• Reservoir and fluid properties must be specified in the Properties tab
