  • Patent number: 9359879
    Abstract: A downhole separator for separating solids from downhole well fluids comprises a cyclonic separation assembly. The assembly comprises a housing with at least one inlet port and an intake member disposed within the housing. The intake member includes a feed tube, a guide member disposed about the feed tube, and a vortex tube coaxially disposed within the feed tube. The assembly also comprises a cyclone body coaxially disposed within the housing and extending axially from the feed tube. In addition, the separator comprises an upper solids collection assembly coupled to the housing and configured to receive the separated solids from the cyclone body. Further, the separator comprises a lower solids collection assembly coupled to the housing and configured to receive the separated solids from the first solids collection assembly.

  • Patent number: 9127535
    Abstract: A deliquification pump for deliquifying a well comprises a fluid end pump adapted to pump a fluid from a wellbore. In addition, the deliquification pump comprises a hydraulic pump adapted to drive the fluid end pump. The hydraulic pump includes a first internal pump chamber and a first pump assembly disposed in the first chamber. The first pump assembly includes a piston having a first end, a second end, and a throughbore extending between the first end and the second end. In addition, the first pump assembly includes a first wobble plate including a planar end face axially adjacent the second end of the piston and a slot extending axially through the first wobble plate. The first wobble plate is adapted to rotate about the central axis relative to the housing to axially reciprocate the piston and cyclically place the throughbore of the piston in fluid communication with the slot.
