P-QX Two-Trip Equalising Plug Assembly
The PTP P-QX Two-Trip Equalising Plug is a plugging device designed to seal off pressure from above and below. The P-QX Plug is designed with a removable Equalising Prong suited for use in wells where sand or sediment might be present and issues may be encountered. The removable Prong comes in 42” length as standard to ensure that it protrudes from the fishing neck of the Lock Mandrel and will not be obstructed by debris for retrieval.
The Plug is run in hole without the Prong in place, providing a large fluid bypass area and allowing fast run- in time. The P-QX plug will locate in a P-X, P-XN, P-R, or P-RN landing nipple by either the use of a positive no-go shoulder, or a selective key configuration. This prevents downward movement, allowing the locking dogs to expand into the locking profile of the landing nipple. The Prong is then run on wireline and stabbed into the Plug to seal off communication from below and isolate the production flow.
The P-QX Two-Trip Equalising Plug Assembly is supplied with rated working pressures up to 10,000 Psi (690 bar) and are available in premium materials to suit virtually any well conditions upon request.
