  • Progressive cavity pump holdback apparatus and system
    Patent number: 9890622
    Abstract: A progressive cavity pump system on a well includes a holdback apparatus. The holdback apparatus has a housing and a one-way bearing in the housing. The housing attaches to the drive head on the well. The one-way bearing allows the motor to drive the pump. The one-way bearing prevents reverse rotation, preventing the sucker rod from unwinding and fluid above the pump from draining, when the pump loses power.
    Type: Grant

  • Downhole separator and method
    Patent number: 6761215
    Abstract: A downhole separator has a housing defining an interior cavity divided into a first chamber and a second chamber by a flow restricting bearing housing. A shaft driven impeller pumps production fluid into the first chamber and to the bearing housing. The bearing housing generates a pressure drop in production fluid entering the second chamber, separating gas from liquid. A vortex generator in the second chamber segregates the liquid to the outside and the gas to the inside of the second chamber. A downhole separation method includes pumping production fluid into a first chamber, and generating a pressure drop in the fluid as the fluid enters a second chamber to separate gas and liquid.
