Lead Seal Cementing Casing Patches

The Logan Lead Seal Cementing Casing Patch forms a permanent sealed connection between two strings of casing and cements them together in a single operation. In addition to utilizing the field proven, compression-type lead seals of the Lead Seal Tubing and Casing Patch, the Lead Seal Cementing Casing Patch incorporates a valve system that allows the patch and running string to be cemented in place immediately after the lead seals have been compressed.
