VERSAGEL HT

Applications

• Increases viscosity in oil-, synthetic-, or paraffin-based drilling fluid systems
• Handles temperatures up to 400 degF [204 degC]. Higher-temperature applications require pilot testing and further technical support.

How it works

VERSAGEL HT high-temperature viscosifier increases carrying capacity and suspension properties, provides support for weight materials, and improves cuttings removal. It also aids in filtercake formation and filtration control.

Good agitation and sufficient shear are required to develop viscosity when using VERSAGEL HT viscosifier to build a fresh mud. Initial system concentration will depend on the specific drilling fluid formulation and drilling conditions.

For system maintenance, VERSAGEL HT viscosifier should be added as needed to maintain downhole rheology, flow properties, and gel strengths in the desired ranges.

Advantages

• Provides gel structure and viscosity for the suspension of weight material
• Increases viscosity for improved hole-cleaning capacity
• Improves filtercake quality and filtration characteristics
• Remains tolerant to many contaminants

Limitations

• Requires sufficient shear and temperature for complete yield, especially when building new drilling fluids
• Requires caution to avoid overtreatment, as full yield may not be realized until circulated downhole

Toxicity and handling

Bioassay information is available upon request.

Handle as an industrial chemical, wearing protective equipment and observing the precautions as described in the safety data sheet.
