Description
Atren D-BCL crosslinkers provide effective delayed cross-linking of guar and its derivatives based linear gel, allowing to reduce pressure during injection and increase its speed. The standard concentration of Atren D-BCL crosslinkers ranges from 1.5 to 3 l/m³. The cross-linking time varies from 30 seconds to 5 minutes depending on the pFH, linear gel temperature values and type of guar polymer.
Atren D-BCL are transported by rail and road, in enclosed transport in line with cargo transportation rules.
Composition
Atren D-BCL™ crosslinkers are a mixture of boron compounds in a hydrocarbon solvent. Crosslinkers provide a delayed cross-linking of guar gum based hydraulic fracturing fluids.
Features
- Provides formation of high-quality elastic cross-linked gel resistant to shear loads, providing efficient delivery of propping agents;
- The basic values of crosslinking time of hydraulic fracturing fluids may vary depending on the hydrogen-ion index pH of guar gum aqueous solution and the grade:
- Atren D-BCL 90, the product allows to adjust the starting time of guar gum cross-linking from 25 to 75 seconds;
- Atren D-BCL 240, the product allows adjusting the starting time of guar gum cross-linking from 70 to 100 seconds.
