In-Line Tool Taxis
In-line Conveyance Tool Taxi — TTB-ILHC (DITS / LOGIQ)
In-line conveyance taxi for Halliburton DITS and LOGIQ tool strings — greater standoff, run with the in-line orienting taxi in 6”+ wellbores.
Description
TTB-IL6C are in-line conveyance tool taxis designed to reduce drag coefficient of a logging tool string.
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” +) in conjunction with the In-line orienting taxis. Its design provides greater standoff, allowing the combination of greater-OD tools in the string.
These taxis use low friction custom ball bearings.
Applications
- Gravity logging up to 80° well deviation.
- Stick-slip and cable tension reduction
- Eliminate risk of tool differential sticking by offsetting tools from the borehole
- Robust design. Very low maintenance requirement.
