Lead Impression Block

The WellEnTech Lead Impression Block, often referred to as an LIB, is used for obtaining impression details of a fish or component within a well bore. The ports permit circulation while running in and out of hole as well as enable circulation of debris away from the target fish.

Description

Features
  • Short robust construction
  • No moving parts
  • Multiple flow ports
  • Low maintenance design
  • Can be redressed after use

Operation

The Lead Impression Block is fitted to the bottom of a BHA. It is made up to the tool string with the correct amount of applied torque, as per the threaded connection on the tool. The tool is then run in hole and the ports enable circulation. Once at target depth, the flow rate can be increased to circulate debris away from the fish. The tool is then run into the fish with either a single jar impact or set down weight, which leaves an indentation on the face of the LIB, which can then be looked at and interpreted when the tool is retrieved to surface.
