Prong-Type Equalizing Housing

The Prong-Type Equalizing Housing is the most commonly used method of sealing and equalizing across the set plug downhole and is recommended for use where there may be debris present. It incorporates a simple Seal Bore Receptacle which is designed to accept a secondary run Sealing Prong.

After the Prong-Type Equalizing Housing has been set, the Sealing Prong is run on a standard JD- or SB-type Pulling Tool to create the sealing plug. To allow safe recovery of the plug, the Sealing Prong is recovered with a standard JD- or SB-type Pulling Tool to ensure equalization has taken place prior to the MATS/GS Pulling Prong being deployed to recover the Plug.
