A selective device capable of holding pressure differentials from above or below when set at any “MX” profile nipple of the same size.

A non-selective device capable of holding pressure differentials from above or below when set at any MXN profile nipple of the same size.

A Top NO-GO wireline retrievable tubing plug, which can be landing in the matched “MF” Landing Nipple. It is designed with a Removable Mandrel for equalizing pressures. The Removable Mandrel is held in the Bypass position by the running tool, to allow fluid Bypass when landing in the seating nipple. When the plug is locked into the desired Seating Nipple, the Removable Mandrel is shifted and locked to close the Bypass Ports. To equalize, a standard wireline pulling tool latches on to and retrieves the Removable Mandrel. After the pressures have been equalized through the Bypass Ports, the plug may be retrieved with a standard pulling tool and proper probe.

A Bottom NO-GO wireline retrievable plug. It can be landing in the “MR” Landing Nipple. It’s working theory and operating is same as the model “MFWG” Bypass Blanking Plug.

A selectively wireline retrievable tubing plug that is designed with a removable mandrel for equalizing pressures. It can be landing in the matched “MF” Landing Nipple. The removable mandrel is held in the bypass position by the running tool, to allow fluid bypass when running through several of the same size nipples. When the plug is locked into the desired seating nipple, the removable mandrel is shifted and locked to close the bypass ports. To equalize, a standard wireline pulling tool latches onto and retrieves the removable mandrel. After the pressures have been equalized through the bypass ports, the plug may be retrieved with a standard pulling tool and proper probe.
