Brochure: FAZEPRO Reversible Invert-Emulsion Reservoir Drill-In Fluid System

Date: 3/17/2017

The advantages of the FAZEPRO reversible invert-emulsion reservoir drill-in fluid system are realized not only in drilling through the pay zone at high performance but also in the completion phase. By simply adjusting the pH of the breaker solution, the wettability of the filtercake transforms from an oil-wet state to a water-wet state. Once the filtercake surface is water-wet, the bridging agent can be easily and completely removed.

The system also mitigates the formation damage and completion impairment of many gravel packs, which have historically restricted lift-off and flowback in addition to blocking uniform accessibility of breakers to the filtercake. For water injection wells, the FAZEPRO system enables immediate postcompletion injectivity without preproducing the well to clean up the reservoir.
