Product feature
Thermostable Alkaline β-Mannanase is a type of biological enzyme breaker applied to oil extraction. It can degrade thickening agents containing mannan, such as guar gum, modified guar gum, xanthan gum, and konjac gum.
And it can reduce the viscosity of fracturing fluid and allow it to flow back to the ground. Also, it can reduce the damage of fracturing fluid to the formation and environmental pollution.
Enzyme activity definition（(Enterprise standards)
At pH 9.0 and under the condition of 90 ℃, the amount of enzyme is taken as one unit, which is required to degrade and release 1μmol reducing sugar (calculated as mannose) from the solution of Mannan with a concentration of 3 mg/m LBG per minute (locust bean powder, Sigma: G0753) .
