BRIDGECARB ULTRA® SYSTEM
DESCRIPTION

The Bridgecarb-Ultra System utilizes sized calcium carbonate particles for pill applications requiring fluid densities below 10.5 lb/gal or where a calcium carbonate system is preferred. The Bridgecarb-Ultra System is composed of two basic products, Bridgecarb-Ultra and Bridgecarb-Ultra Fine.  Incorporating an increased concentration of bridging particles below 10 microns in combination with broad particle distributions, the Bridgecarb-Ultra products are able to provide improved filtrate control with a significant reduction in polymer levels.

The new Bridgecarb-Ultra and Bridgecarb-Ultra Fine can be used for:

  • Lost circulation pills
  • Perforating fluid loss pills
  • Pre/post gravel pack fluid loss pills
  • Sealing annular leaks in casing

The Bridgecarb-Ultra products may be mixed in potassium chloride, sodium chloride, calcium chloride, and sodium bromide brines.  Bridgecarb-Ultra and Bridgecarb-Ultra Fine fluid densities range from 9.0 lb/gal to 13.5 lb/gal depending on the base brine and concentration of bridging solids utilized. Bridgecarb-Ultra products are packaged in 50 lb or 25 kg sacks.

FEATURES
  • Applicable across a broad range of fluid densities
  • Blended calcium carbonate products contained in the Bridgecarb-Ultra and Bridgecarb-Ultra Fine products provide optimized broad particle distributions for reduction in polymer concentrations, and improved sealing characteristics over a wide range of reservoir permeabilities
  • Bridgecarb-Ultra products when combined with Sluggits utilize a series of overlapping particle distributions which provide formulating flexibility to meet formation requirements in lost circulation applications
  • Incorporates a proprietary derivatized starch/biopolymer combination for outstanding rheological and suspension properties to prevent settling at bottom hole temperatures up to 250°F
  • This polymer combination creates a unique synergistic effect creating an optimum viscosity profile giving Bridgecarb-Ultra long-term suspension stability
  • Improved bridging/filtration control results in thin, ultra-low permeability filter cakes
  • Compatible with Ultra Breake-M®, the patented internal breaker system for filter cake removal
