drillpipe conveyed

1. adj. [Formation Evaluation]
Describing sensors that are embedded in drill collars in order to record measurements-while-drilling.
2. adj. [Formation Evaluation]
Pertaining to the use of drillpipe to move wireline logging tools up and down a borehole. In difficult conditions--high well deviation, rough hole--wireline logging tools cannot reach the bottom of the hole under their own weight. In drillpipe-conveyed logging operations, the tools are moved mechanically by the drillpipe, while a wireline maintains the electrical connection.
