“C” PLUG

The Type “C” Equalizing Plug is anequalizing sub that holds pressuregenerated from the bottom only. Itcan be used as a pump throughplug if needed. When used inconjunction with the Type “B”, “H”,and “F” Equalizing Subs, the upperend of the bean housing serves asa valve which seats and seals on atapered seat that is present in allType “B”, “H”, and “F” subs. Thissame tapered seat is present in the“B” and “W” Mandrels so that the“C” Plug could be used on themwithout another equalizing submade up to it. The bean has asecondary valve which sticks outabove the bean that must bepushed off seat, using anequalizing prong made up the theproper pulling tool, in order toequalize. This is accomplished byapplying tool string weight on itprior to pulling the locking mandrel.

“D” PLUG (1 1/2”, 1 3/4”)

The Type “D” Equalizing Plug is aplug that is designed to holdpressure from below. It can beused in conjunction with manylocking devices to bleed off a wellin order to perform repairs orreplacement of surface equipment.It also has pump throughcapabilities that would allow anoperator to kill a well. A pullingprong is needed to equalize thesesubs. The prong actuates asecondary valve which allowseither fluid bypass or pressureequalization.

DUAL FLAPPER CHECK VALVEThe Dual Flapper Check Valve is adevice used to prevent pressure orfluid from passing up through theassembly. It is used in conjunctionwith a “TICX” or “TICR” LockingMandrel. The Dual Flapper CheckValve has two flapper assemblies withseals to prevent pressure of fluid by-pass upwards.

The Dual Flapper Check Valve is aback pressure valve that allows theoperator to pump through theassembly while allowing maxiumumflow through the assembly withminimal restriction.

Equalization can be achieved byplacing an equalizing sub above theassembly, or by running a prongattached to the pulling tool that willknock both flappers off seat.

Pump Thru Check Valve

The Pump Thru Check Valve is designed to fit onto the Peak SIM Plug and most standard wireline conveyed lock assemblies and is used where there is a requirement to hold tubing pressure from below whilst allowing a maximum pump through capability. The Peak design incorporates several key differentiating features including a reversible metal-to-metal seal for optimum working life, a secondary bronze filled Teflon seal to initiate metal to metal sealing at low pressures and mass reduction in the piston valve to reduce stress loading on the Inconel Return Spring also designed to extend working life.

Applications

■ The Pump Thru Check Valve can be used when there is a requirement to hold tubing pressure from below whilst allowing a pump through capability

Features & Benefits

■ Reversible metal-to-metal seal designed to extend working life ■ Secondary bronze filled Teflon seal to initiate metal to metal sealing

at low pressures ■ Mass reduction in the Piston Valve reducing Return Spring stress

Pump Open Sub

When deployed as part of a downhole plug assembly, the Pump Open Sub is primarily designed to act as a single barrier against well-bore contents.

The Pump Open Sub Plunger is secured in place with a series of shear screws which are designed to shear out when a predetermined pressure is applied from above the Pump Open Sub.

Once the Plunger is sheared out, there is a clear flow path through the Pump Open Sub. This allows for full equalisation across the barrier device, circulation, communication to prevent recovery of “wet” tubing strings or production of well bore contents.

Applications

When deployed as part of a downhole plug assembly, the Pump Open Sub can be: ■ used as a barrier to allow setting of hydraulically-set packers having to make

an equalising run prior to plug recovery ■ remotely “opened” by pressuring the tubing above to the pre-set shear

rating. The well can then be brought back online without any intervention ■ used for creating tubing overbalance prior to Fracture Stimulation

Operations ■ deployed as a contingent equalising device in high debris environments ■ used as a mechanical barrier during wellhead removal / tree valve

maintenance

Features & Benefits

■ Can be retrofitted to suit existing Lock Mandrel / Equalising Assemblies ■ Multiple setting values (500 psi minimum - 3000 psi maximum) in 500 psi

increments ■ Large flow area after pump out in flow type / circulating applications ■ Sheared plunger retained within the sump of Pump Open Sub eliminating

unnecessary well debris ■ Minimising wireline runs ■ Can be sheared out even if debris restricts access to primary equalising

facility by applying sufficient pressure
