Product Description

Product Details
The Impression Block used in fishing operations is an assembly of a steel body and a soft lead founded at the bottom. It is designed to enable the operator to determine the configuration of the top of the fish and to locate its position in the well bore.
It's use to enable the operator to select the proper tools needed to successfully complete the fishing operation.
 

Impression Block is an effective tool used to determine the dimensions, configuration, condition, and location of the top end of a fish in the hole.

Construction

KAIDI Impression Blocks are manufactured with a high strength alloy steel body and a soft lead insert at the lower end. All impression blocks come with a watercourse that allows flushing of the fish top before the tool is lowered against it. Impression blocks without a watercourse can be furnished upon request.

Operation

Attach the impression block to the bottom of the fishing string and lower into the well-hole. Do not rotate the tool, slowly lower the impression block to the point of contact with the fish. Apply weight on the impression block to make an imprint of the fish on the soft lead insert and lift it from the hole.
