Product Sheet VERSATROL M1 Blended Asphaltic Resin
Reduces HPHT fluid loss in all oil-based systems.
VERSATROL M resin is a naturally occurring asphalt used for high-pressure, high-temperature (HPHT) filtration control in VERSA oil-based systems.
VERSATROL M resin has a lower softening point than the regular VERSATROL resin, which makes it suitable for use over a wide range of temperatures. It is often used to seal low-pressure and depleted formations.
|Typical Physical Properties|

|Softening point||365–400 degF [185–204 degC]|
VERSATROL M resin is designed to be used in applications where the anticipated bottomhole static temperature does not require the higher limits of the regular VERSATROL resin. VERSATROL M resin reduces both API and HPHT fluid loss in all oil-based muds. It helps improve the overall emulsion stability, thermal stability, and suspension characteristics of most oil-based formulations. VERSATROL M resin also increases viscosity, especially at lower temperatures due to its partial solubility.
Typical concentrations range from 2 to 8 lbm/bbl [5.7 to 23 kg/m3], with occasional daily additions in the 0.25 to 0.5 lbm/bbl range [0.71 to 1.43 kg/ m3]. High-temperature situations and special applications require higher concentrations—as much as 10 lbm/bbl [29 kg/m3].
When used in the initial formulation, it is recommended to add VERSATROL M resin last. For existing systems, the product can be added at any time, mixed slowly during at least one complete circulation. Monitor solids control equipment for several circulations after initial addition to ensure the product is not being discarded. Pilot testing is advised to determine the necessary treatment to achieve the desired results and to observe the change in mud properties.
Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions described in the safety data sheet.
VERSATROL M resin is packaged in 50-lbm [22.7-kg] and 55.1 lbm [25-kg] multiwall paper sacks. Store in a dry, well-ventilated area. Keep container closed. Store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding, shrink-wrapping, and stacking.
