The DTHP plug is RIH in an open position allowing the operators to circulate down to the deep set barrier. Once the well is displaced, the production packers can be set against the deep set barrier, then a pressure test and inflow safety valve test can be conducted. The sleeve is then shifted in a closed position (ISO 14301 V0 seal), providing two well barriers.

The blowout preventer equipment (BOP) can be rigged down and a vertical X-mas Tree (XT) installed. The well can be lined up for commissioning from either a production vessel or FPSO. Just this process alone saves the client multiple days in rig time resulting in savings of millions of dollars.

The plug is opened by pressure pulses sent down to the trigger system installed in the DTHP plug. The trigger system is a redundant system.

The initial specification: the 8.81” DTHP comes with ID of 4.75”. The OD is designed to allow clear passage of control lines when this assembly was run in 10 ¾” casing.
