Well Drilling Fishing Impression Blocks

Well Drilling Fishing Impression Blocks

Rotometals manufactures and re-casts Well Drilling Fishing Impression Blockheads in various sizes as per each client's exact requirements.

With our exchange Re-casting program, you send us your used impression heads, and we will melt off and recast lead to your OD specifications. 

Impression Blocks are an accessory tool used to accurately determine the dimensions and configuration of the upper end of a fish as well as to check its condition and position in the well bore.

The soft lead lower end of the impression block captures an impression of the fish upon making contact.

Impression blocks are manufactured with a pin or box up connection and a layer of soft lead on the lower end of the tool.

Impression blocks are manufactured from 4140HT or 4145M material.

When ordering, please specify:

  • Desired OD
  • Box or pin up connection
  • API connection size (ex. 3-1/2” API IF, NC-38)
  • Overall length of tool
