The D-H Tension Packer is for use in water flood, injection or producing wells. This tension packer has a built-in safety system to eliminate problems should conventional retrieval methods fail. Right-hand rotation releases the first safety joint allowing the slips to pull off the cone and release the packer. Should the packer fail to release, a second safety joint can be broken to release the packer. This safety feature allows for circulation down the tubing to remove debris.
In addition, the D-H Tension Packer is available for open-hole applications and incorporates dual elongated packing elements and deep wickered slips for better bite into the formation.
