Downhole pump multiphase fluid conditioner

Abstract

A downhole multiphase fluid conditioner is described that includes a head, a base, and a gas separator having a plurality of gas exits and an uphole end and a downhole end. Two or more pump stages are operably connected to the head and the uphole end of the gas separator. Each of the two or more pump stages are a contrahelical stage, a centrifugal stage, a gas handler centrifugal stage, or any combination thereof. The downhole multiphase fluid conditioner further may include either (1) two or more pump stages operably connected to the base and the downhole end of the gas separator wherein each of the two or more pump stages are a contrahelical stage, a centrifugal stage, a gas handler centrifugal stage, or any combination thereof; or (2) a gas handler centrifugal stage operably connected to the base and the downhole end of the gas separator.
