Advanced fluids technology
Ensure low-rheology drilling fluids without barite sag.
Concentrated colloidal suspension technology
A key component of WARP advanced fluids technology, WARP OB CONCENTRATE technology is a high-density colloidal suspension of specially treated barite in a low-toxicity mineral oil used to densify oil-based fluids for drilling and completion applications

WARP OB CONCENTRATE technology enables exceptionally low-shear-rate viscosities with no particle settlement and sag for critical well drilling. Drilling applications include
Invert oil-based drilling fluids incorporating WARP fluids technology have been used in extended-reach drilling and through-tubing drilling applications in the North Sea region. Torque reductions up to 25% have been measured inside casing, and dilution factors have been reduced by as much as 50% compared with offset wells.
The colloidal nature of WARP OB CONCENTRATE technology imparts zero sag and settlement allowing primary solids control equipment to be aggressively configured resulting in demonstrably lower discharge volumes compared with conventionally weighted fluids. The intrinsically low viscosities of invert oil-based drilling fluids using WARP OB CONCENTRATE technology enables higher pump rates, lower swab and surge pressures, and improved ECD management.
WARP OB CONCENTRATE technology is diluted with base oil to the required fluid density and formulated to the required fluid specifications with other additives and products for completion fluid applications up to densities of 19.2 lbm/galUS [2.3 kg/L]. WARP OB CONCENTRATE technology has been extensively used for completion fluid applications in the Caspian Sea region for long-term packer fluid applications and for reservoir drilling. Applications for WARP OB CONCENTRATE technology completions fluids include
WARP OB CONCENTRATE technology is supplied as a bulk liquid and is handled in the same way as conventional oil-based drilling fluid. Handle as an industrial chemical, wearing protective equipment and observing the precautions as described on the SDS.
WARP OB CONCENTRATE technology is supplied in ISO tanks; intermediate bulk containers; or bulk by boat, tanker, or rail car. The fluid is inherently stable and self-suspending because of the particle size. Monthly circulation of bulk tanks is recommended.
