A single-package dual-function solution for coiled tubing and any critical-parameter drilling and completion application

Equipment configurations on rigs have often not been optimally designed for safe and efficient execution of coiled tubing (CT) and other drilling and completion applications requiring precise monitoring of pressure and solids-control parameters. M-I SWACO, a Schlumberger company, has engineered its compact PRESSURE AND FLUID MANAGEMENT specifically for the unique demands of CT drilling and other applications requiring precision in pressure and solids control while having a small equipment footprint.

A seamless solution for pressure and solids control

Typical pressure and solids control equipment layouts have frequently been unwieldy, making them ill-suited for space-challenged locations and presenting logistical and economic challenges. In addition, operators and drilling contractors have often found themselves at an operational disadvantage when trying to head-off well control, stuck pipe, reservoir damage and other downhole and environmental issues that can render a project uneconomic. The modular PFMS unit provides compartmentalized equipment in a single skid-mounted package that incorporates the latest generation of precise field-tested pressure and solids control technologies. The system has been shown to provide continuous closed-loop pressure control and simultaneous drill solids and gas removal in a host of applications, including workovers, cleanup operations, fracing and flow-backs, re-entry, and recompletions.  It is also suited for conventional drilling operations when a particularly small equipment footprint is required. The modular small-footprint design, which includes self-contained plumbing and electrical systems, means that the PFMS requires minimal rig-up and rig-down time.  It incorporates advanced technologies such as the AUTOCHOKE unit and MONGOOSE PT dual-motion shaker to deliver automatic and continuous pressure control while  effectively removing drill solids and entrained gas, thus reducing costs and optimizing safety on the rig.

Key features of a typical layout include:

Pressure control  

• Specially selected Choke Manifold
• Dual AUTOCHOKE units for precise control of well pressure with improved wear and anti-plugging characteristics for severe service conditions
• Field-proven mud/gas separator for removing high volumes of free gas
• 154-bbl, three-compartment fluid-collection tank equipped with pumps,  agitators, gun lines and transfer lines
• Vacuum d-gASSEr† units for removal of any gas still entrained in the fluid after solids-control processing 

Solids control

• Dual-motion MONGOOSE PT Shaker fitted with patented pre-tensioned  MAGNUM XR mesh screens
