Cross-Linkers

Metallic cross-linkers connect the polymer chains and greatly increase the apparent viscosity of a gelled fluid, which increases the proppant carrying efficiency, allowing for higher proppant concentrations to increase the fracture width. Fluid loss is also reduced, which assists in increasing the fracture length.

BXL 10

Aqueous borate cross-linker (Ph 9.0-11.0)

Aqueous borate cross-linker that contains internal buffers to automatically raise the pH of the gelled fluid to the range of 9.0-11.0 (optimally 10.0). Provides an immediate cross-link and is stable to 250°F (121°C). Normal concentration is 2 gal/1000 gallons (2 L/mᵌ).

BXL 8.5

Aqueous borate cross-linker (Ph 8.5-8.7)

Aqueous borate cross-linker that contains internal buffers to automatically raise the pH of the gelled fluid to the range of 8.5-8.7 and enable the use of enzyme breakers. Provides an immediate cross-link for low temperature applications below 140°F (60°C). Normal concentration range is 1-3 gal/1000 gallons (1-3 L/mᵌ).

BXL-STD

Delayed borate system for HPG gels

Delayed borate systems help to minimize friction pressures by delaying the cross-link time of the base gel. Normal concentration is 2 gal/1000 gallons (2 L/mᵌ). BXL-STD provides a 2 to 3 minute delay for HPG gels.
