Borehole cementing

Borehole cementing takes place during exploration as well as during stimulation. By special procedures the fresh cement as a slurry is pressed into the annulus of the well. The cured cement seals and strengthens the gap between the piping and the rock. This process improves the production of crude oil or natural gas by cemented piping.

 

Tylose® H grades with a low viscosity level are recommended 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.
