摘要 |
Slip segments with a friction medium are used to anchor a downhole tool in a well. Each slip segment has a slip segment body made of a drillable material. A friction medium is applied to the outer surface of the slip segment body so that the outer surface of the slip segment has an increased holding capability in the well.
