Detailed
The releasable reversing spear type DLM-T is a tool designed to recover and back off the stuck pipe-shaped fish like drill pipe, oil tubing, etc. Backing-off operation and fishing job are performed through the interior bore of the fish by using the spear. The held fish can also be released down-hole when required. Additionally, the fishing job can be conducted while the well-bore is being circulated.
