TTC-IL6OTTB-IL6O
Description
The IL6O are in-line tool taxis designed to orient & reduce the drag coefficient of a logging tool string. They come in two variants: bush bearing (TTC) and ball bearing(TTB).
Taxis make up in-line, directly to wireline logging tools, without the need for adapters.
The Taxis are designed for use in small wellbores (6.0” +)
These taxis are available with tungsten carbide bush bearings or Ball Bearing.
Applications
- Gravity logging up to 80° well deviation
- Orient logging tool sensors, cores, pressure measurements and samples without the need for standoffs, bow springs, tool turners etc.
- Stick-slip and cable tension reduction
- Eliminate risk of tool differential sticking by offsetting tools from the borehole
- Robust design. Very low maintenance requirement.
