GARAMITE-1958
Low-end rheology synergist
GARAMITE-1958 is a mixed mineral thixotrope that boosts
6-rpm rheology, allowing for proper hole cleaning and fasterdrilling, providing minimal effect on high-end rheology.
With the ability to improve both yield point (YP) andplastic viscosity (PV), GARAMITE-1958 can create a robust
system in any oil-based mud program. GARAMITE-1958
incorporates much faster than traditional organoclays
and can be incorporated at any time, including whileat a mud plant, or at a rig through a chemical hopper.
To test GARAMITE-1958, a typical mud system that wouldexperience issues with low-end rheology was chosen.
GARAMITE-1958 performance was benchmarked againstorgano-attapulgite. The test system was a 12-ppg,
75/25 diesel invert system with the following formulation:

The complete rheological data obtained from the variations are shown below. The data wascollected after hot-rolling at 250° F for 16 hours and were measured at 120° F.

6-rpm performance as 3 lb/bbl of organo-attapulgite withminimal increase in PV. This results in 6 times more efficientperformance over organo-attapulgite, providing superiorvalue.

GARAMITE-1958 provides superior performance andeconomics per use in an easily manageable 10-kg sack.
The low-end rheology boost allows for better holecleaning leading to an increase in rate of penetration (ROP).

6 x Efficiency

The efficiency of GARAMITE-1958 in boosting low-end
rheology is demonstrated in G. 02. Small additions ofGARAMITE-1958 have a greater positive impact on mud
properties in comparison to higher doses of other clay
based additives.
