High-Pressure Debris Unit

Superior Performance

Drillpipe debris trap deck unit (DPDT-DU)

Gen 4

Current pit trash and well trash filtering systems require repeat changeouts and multiple units based on operational complexity.

The Gen 4 DPDT-DU is a 15ksi rated active surface filter meant to provide reliability and durability above and beyond expectation with customization available for long term installations

DPDT-DU Gen 4 Spec Brochure(SPI) 2

 

 

Details

Contains wire wrap screens gauged based on customer mud and brine fluid systems and may be sized to even capture gravel pack sand.

Contains single3” 1502 WECO connections for inlet/outlet integration ease and bypassing in the event of severe plugging, thus permitting rates in excess of 18bpm.

Capable of backflushing individual barrels while still going downhole; eliminating operational pause or preventing downtime during critical pumping operations.

An integrated capturing system allows for inspection of captured debris during the operation.

Digital gauges are provided to identify which barrel is experiencing plugging and to allow an accurate gauge of pressure drops for the surface system

The compact DPDT-DU Gen 3 may be mobilized for shorter, simple operations or the DPDT-IL may be adapted to a single joint of drill pipe permitting installation on deck, below the top drive, or downhole
