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.

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.

Abstract translation: 井下分离器具有壳体，其通过流动限制轴承壳体限定分为第一室和第二室的内腔。 轴驱动的叶轮将生产流体泵送到第一室和轴承壳体中。 轴承壳体在进入第二室的生产流体中产生压力降，从而将气体与液体分离。 第二室中的涡流发生器将液体分离到外部，将气体分离到第二室的内部。 井下分离方法包括将生产流体泵送到第一室中，以及当流体进入第二室以分离气体和液体时，在流体中产生压降。
