BridgePRO - Bridging Agent Size Selection Model

BridgePRO Introduction Video

Protecting the pay zone from damage is critical to realize the full potential of any well. Reservoir drill-in fluids (RDF) are designed to prevent formation damage due to fluid invasion and solids plugging. A poorly designed RDF may react with the formation fluid creating blockage or restriction for the natural flow of the reservoir. A large range of undesired solid particles from drill solids, fluid chemicals and clay viscosifiers may end up plugging the reservoir pores. The technique for designing a non-damaging RDF is to start with selecting bridging agents with an ideal size distribution to effectively seal the formation surface.

Pegasus Vertex, Inc. has developed BridgePRO, a bridging agent size selection software that aids in the determination of the optimum calcium carbonate blend to achieve maximum bridging of sandstone reservoirs. The software optimization is based on specific formation characteristics and the particle-size distribution of available grades of calcium carbonates.
