XAN-BORE
BIODEGRADABLE VISCOSIFIER FOR FRESH WATER, SEAWATER OR HIGHLY SALINE SYSTEMS
DESCRIPTION
Xan-bore is a premium quality biopolymer powder designed to provide maximum solids suspension and hole cleaning in vertical and highly deviated wells as well as horizontal directional drilling applications. Xan-bore is a distinctive product, able to produce a thixotropic shear thinning fluid. Xan-bore also acts as a very effective mud filtrate viscosifier.
APPLICATIONS/FUNCTIONS
Xan-bore can be added to a pre-hydrated bentonite based fluid or can be used as a single viscosifying additive in fresh, brackish or saturated salt water.
Xan-bore fluids are highly shear thinning which improves bit cleaning and ROP significantly. The fluid will revert to higher viscosities at low shear rates. This unique property provides many benefits in highly deviated wells and in HDD bores by providing excellent carrying capacity of coarse cuttings, sand and gravel.
In HDD drilling, improved hole cleaning and cuttings transport allows for quicker and easier back reams and pull backs on longer bores.
In CBM drilling xan-bore’s highly thixotropic mud filtrate limits damage to coal seams and cleats.
