ActiVis LSR
ActiVis LSR is a blend of viscosifiers and synergistic
agents designed to promote low shear rate viscosity
(LSVR) in drilling fluid systems. When mixed with
fresh water, brines, or formates it it produces
high Brookfield readings while minimizing Fann readings
in the high shear ranges. This produces a drilling,
workover and completion fluid with excellent suspension
and hole cleaning properties yet provides low equivalent
circulating densities. It is not effected by most
drilling contaminants and exhibits no excessive
gelation. When combined with ActiPac it forms the base stabilizing
fluid for the HYSSTER system.

Applications
ActiVis LSR’s use provides a highly
structured base fluid with exceptional LSRV properties
resulting in excellent aphron stability. Combining
these features with the sealing attributes of enhanced
aphrons enables us to deliver an ideal drilling,
workover and completion fluid for permeable and
micro-fractured zones. The sealing efficiency, LSRV
and low ECD properties make this a fluid of choice
for high angle and horizontal applications; particularly
in areas where tight drill windows are present.
ActiVis LSR is recommended in concentrations
of 15.0 to 30.0 pounds per barrel for optimum performance
in most drilling fluid applications.
ActiVis LSR is readily dispersible and can be
added directly to the drilling fluid through a mud
hopper.
Advantages

highly inhibitive in shales and clays,
- Prevents
formation invasion and losses,
- Enhances
formation clean-up,
- Reduces
tight hole problems,
- Mitigates
the potential for differential sticking,
- Enhances
rate-of-penetration.
