CMHPG LH-201

400-6362-678

Product: Carboxymethyl Hydroxypropyl Guar Gum
Abbreviation: CMHPG
CAS Number: 68130-15-4

Description:

LH-201 is double modified guar gum from carboxymethyl hydroxypropyl ether, specially designed for petroleum industry as additives for aqueous and water/methanol-based fracturing fluids.

Applications:

LH-201 in aqueous fluids is used in drilling deeper wells and hotter oil and gas wells hydraulic fracturing. These applications utilize its properties to increase viscosity, reduce fluid loss and decrease fluid friction. In these systems, crosslinking can be delayed until the fluid is entering the fracture, significantly reducing the required pumping pressure. It also produces less “residue after break” within the fracture.
