Invert-emulsion reservoir drill-in fluid system

Liquid texture

Minimize formation damage in a variety of reservoirs

VERSAPRO invert-emulsion reservoir drill-in fluid system is designed specifically for drilling openhole-completed reservoirs. The system minimizes formation damage problems such as oil wetting, emulsion blocking, and solids plugging while retaining the performance advantages of invert-emulsion fluids—high drilling ROP, lubricity, and wellbore stability. 

Owing to the higher priority of minimizing formation damage and compatibility with completion assemblies, VERSAPRO system fluids differ from conventional invert-emulsion fluids in their design and application. The emulsifier and wetting agent package, the type and size of bridging material, and all components required are reviewed for the best combination of drilling and completion characteristics.
