Protects casing and drill pipe integrity
The RotoTEC® is a drill-pipe deployed tool designed to eliminate casing wear and reduce torque and drag in the drill string. Unwanted casing wear and torque and drag can occur when the drill pipe tool joints come into contact with the casing under side-load during any pipe movement, creating a frictional load between the surfaces.
The RotoTEC has a less stiffening effect than rigid sub based tools and a modified protector can be manufactured to provide additional Total Flow Area (TFA) should Equivalent Circulating Densities (ECD) become an issue.
Successful installations have resulted in as much as a 30 to 35% reduction in torque and, in one case, TD was reached in 1 to 2 days rather than the 4 to 5 days estimated without the tool.
