THE NEXT LEAP IN SEPARATION TECHNOLOGY
The reliable, operator friendly VSM® Multi-Sizer liquid/solids separator provides high performance and flexibility for modern day drilling practices.
The VSM® Multi-Sizer separator is first to introduce Constant-G Control™ (CGC) Technology, an adjustable g-force to meet drilling rates and separation efficiency.
Constant-G Control™ (CGC) Technology
The new CGC technology measures basket acceleration and maintains a constant g-force. Once the adjustable CGC optimum g-force setting is determined, the setting is locked-in for the duration of that hole section. CGC essentially works like cruise control. With conventional shakers, as liquid/solids loading increases, motor RPM stays the same, while g-force decreases. With the VSM Multi-Sizer CGC, as drilling process rates change (liquid/solids loading increases on the screening areas), motor RPM will adjust to maintain a constant g-force setting with no deterioration in performance or load handling capacity.
The VSM Multi-Sizer separator also offers a flexible flow (Flex-Flow) system that can run in two unique operating modes: "in-series" and "in-parallel". Changing modes is easily accomplished with an adjustable flow diverter.
“In-Series” Operating Mode
When operating in the “in-series” mode, the unit can classify solids into distinct particle sizes by using screens of differing API designations. This breakthrough in separation effectiveness enables barite or designer solids, including lost circulation material (LCM), to be effectively recovered on the first primary deck fitted with four screens. The built-in solids recovery trough on the first primary deck allows for easy switching between the collection and disposal of solids in the Flex-Flow modes. The secondary deck, also fitted with four screens, provides an additional high screening area deck for the removal of fine or low gravity solids.
“In-Parallel” Operating Mode
Operating in the “in-parallel” mode effectively doubles the fine screening area, which allows for finer screening and more volume removal while drilling within the intermediate and bottomhole sections. Primary decks #1 and #2 are screened with the same API designations. An adjustable internal weir allows for flow equalization between the first and secondary primary decks, which optimizes screen utilization. Selecting Flex-Flow modes is easily accomplished by sliding the manual flow diverter. A single clamping action on the diverter is all that is required of the Pneumoseal to switch between "parallel" and "in-series" operations. This easy operation is done in a matter of seconds, by a single operator without the use of hand tools.
Composite Materials
National Oilwell Varco® has designed the Brandt® VSM Multi-Sizer separator to provide an improved power- to-weight ratio by use of composite materials (patent pending) throughout the vibration basket. This provides an improved g-force rating without the need for increased drive system requirements. Composite materials also provide exceptional corrosion resistance in high fluid flow areas.
The VSM Multi-Sizer separator features balanced-elliptical motion to effectively separate solids from liquid. Screen changes are quickly facilitated with the field-proven Pneumoseal clamping and sealing system as used on the VSM 300 shaker. The HVAC hood, a standard feature on the VSM Multi-Sizer separator, routes hazardous fumes away from the unit and into a ventilation system.
