PERFORMAX System Products and Functions
FUNCTION
Sealing polymer utilized to generate semi-permeable membrane for shale stabilization.
Secondary function is as bridging material in pore throats of depleted sands to eliminate
differential sticking and lost circulation.
Aluminum and resin complex that works in combination with MAX-SHIELD to
generate semi-permeable membrane and improve well stability.
Cuttings encapsulation and improve cuttings integrity
Amine-based material for suppressing the hydration and swelling of reactive clays and
gumbo.
A high-molecular-weight xanthan gum polysaccharide that includes an enhanced
dispersibility feature used as an effective viscosifier in most waters regardless of salinity
or hardness
Reduce bit balling and increase rates-of-penetration
Low-viscosity-grade PAC material to reduce API filtrate
Sulfonated resin for HT-HP filtrate control
PERFORMAX Mixing Procedures at Liquid Mud Plant (LMP)
1. The use of a shearing device is recommended.
2. Remove all trash, solids, etc. from the water- base mixing tank
3. In a separate tank, add fresh water and treat hardness to < 200 mg/L with soda ash.
4. Pre-hydrate MILGEL ® at a concentration of 30 lbm/bbl with a sufficient volume of water
to achieve a concentration 3 lbm/bbl in the final mix. For example, if the total volume of
finished mud needed is 2000 bbl. Multiply 2000 bbl by 3 lbm/bbl = 6000 lb. of gel.
Divide 6000 lb. by 30 lbm/bbl = 200 bbl pre-hydrated gel required.) Allow gel to hydrate
for a minimum of 3 hours after mixing. Adjust pH of mixture to 10.8 – 11.0 with
caustic soda.
5. Transfer calculated volume of pre-mixed gel to give 3 lbm/bbl in the final volume to the
clean mixing tank. For example, if the final volume in mix tank = 300 bbl. 300 bbl. * 3
lbm/bbl = 900 lb. 900 lb. / 30 lbm/bbl = 30 bbl pre-mix.)
