A hydrocyclonic desander taken from the Fat Man platform and converted for higher flow rates — positioned below a rod pump packer-style separator setup. Can be run in tandem with another degasser desander, like a FatMan 239, for two stages of sand separation on very sandy wells.
HIMARS is a high-performance desander system for tackling sand and other debris in oil and gas wells. Using hydrocyclonic-style media separation, it removes solid particles from the production stream to ensure optimal sand control. Positioned below a rod pump packer-style separator setup, the system features a heavy-walled slotted sub for unrestricted flow from the reservoir. A single wire-reinforced cup packer provides enough isolation to divert flow into the desander — which is taken directly from the Fat Man platform and converted for higher flow rates, with erosion coatings for wear resistance and durability. On very sandy wells, HIMARS can be run in tandem with another degasser desander — a FatMan 239, for example — to create two stages of sand separation.
A Fat Man-derived desander, rate-converted and positioned below the packer-style separator.
A heavy-walled slotted sub sits below the packer-style separator, giving unrestricted flow from the reservoir into the desander.
A single wire-reinforced cup packer provides enough isolation to divert flow into the desander section, without needing a full setting mechanism.
The desander core is taken from the Fat Man platform and converted for higher flow rates, with rate-specific cyclonic spirals and erosion coatings standard.
HIMARS can be run in tandem with another degasser desander — a FatMan 239, for example — to create two stages of sand separation on very sandy wells, catching what the first stage lets through.
