Bidirectional Chamber Trap (BDCT)*

The Bidirectional Chamber Trap is a surface filtration system designed to integrate into a rig standpipe manifold configuration. It is the goal of the BDCT to passively filter both large and small debris from fluid systems entering and exiting the well without the need for reconfiguration.

The parallel horizontal design, in conjunction with offset entry/exit, and possum belly permit the BDCT to filter particles via screens and settling that may disrupt downhole operation of delicate tools or simply plugging of pit suction points. The parallel designs offers the opportunity to change out screens, flush the unit, and test broken connections without shutting down fluid movement or the current operations. In addition, modules may be added to aid with shearing fluid or ball catches.

This provides

• Assurance to operate without restricting rates or pressure while capturing debris that may cripple an operation downhole.

• Additional pit filtration when reversing.

• On the fly shearing ability for Mud, HEC or indication and trapping of large debris that has entered the system. 

Features

• Rating equal to or in excess of rig manifold.

• Ability to retest connections without pressure testing manifold or equipment upstream/downstream.

• Interchangeable screens selected based on operator preference.

• Flushing system that utilizes current fluid movements and does not require shut down.

• Screen inspection capability that does not require shut down.

• Modules to aid in fluid shearing or ball catch.

• Inlet/outlet pressure gauge to identify capturing of large debris detrimental to operations.

• Filtration during both forward and reverse circulation without any reconfiguration.
