Protect your ESPs, rod lift pumps, and gas lift completions from solids in production by cleaning fluid flow.
Protect your ESP pump from sand and solids during shutdowns
During planned and unplanned ESP shutdowns, sand and solids (e.g., scale) suspended in the tubing column fall and settle into the fluid stage of the pump and can lead to multiple failed restart attempts. Excessive torque during these restarts risks large motor current, a consequent increase in motor winding temperature, reduced ESP run life, and shaft breakage. Our proprietary Sand Fallback Shield above the ESP guards against these eventualities.
Under normal operation, the ESP lifts oil to surface unrestricted through the Sand Fallback Shield. During a shutdown, the shield restricts access, preventing sand and solids from falling into the pump. When the ESP restarts, the Sand Fallback Shield’s vertically and radially distributed flow area enables jetting and agitation of the solids settled on the exterior of the shield. Unrestricted production resumes up the cylindrical shield and out through it, along the tubing. The shield also permits injection from above at rates up to 4 bbl/min for well stimulation or cleanup.
