Completion, workover and stimulation fluids (fracturing)

During the exploration and stimulation process steps of crude oil/natural gas, special fluids are used during production, workover and stimulation of the production wells and producing horizons. Tylose® grades with high thickening effect, high pseudoplasticity, easy initial mixing by adequate delayed solubility and good dissolving behavior in the field are recommended. In completion and workover fluids, saturated saline solutions or brines are used. Tylose® types with a medium to high level of viscosity will give the required consistency of these fluids.

 

High viscosity grades of Tylose® H are recommendend for these applications.

Tylose® is used in the production of crude oil and natural gas. Its enormous water retention capability and electrolyte tolerance makes Tylose® a powerful fluid loss additive for borehole cementing. Higher viscous Tylose grades are suitable additives during the drilling process steps stimulation, completion and workover.
