The PRO V+ ™ Pre-Cement Spacer is an adjustable rheology cement spacer engineered to stop lost circulation during primary cementing before it starts. The tailored spacer system uses a proprietary pozzolantic chemistry with carefully selected additives to help prevent lost circulation in porous and fractured formations, while enabling downhole fluid separation, cleaning, and compatibility.

Thorough lab testing verifies the spacer significantly enhances spacers in cementing jobs where seepage, partial losses to total fluid losses are observed. In cases where there is risk of severe losses, PRO V+ spacer can be enhanced with our specifically sized particle proprietary lost circulation materials to help prevent severe losses and achieve desired top of cement (TOC).

Plugging and sealing up to 500 microns and fractures up to at least 3000 microns are plugged when tailored with our proprietary lost circulation material (LCM).

Formulations are Acid Soluble, non-damaging to the formation and support operations up to 400°F, with densities up to 19ppg
