Abstract
A well production apparatus includes a down-hole gear pump and a transport assembly to which the gear pump is attached. The transport assembly is formed from a string of modular pipe assemblies having one or more passages for carrying production fluid from the bottom of the well to the surface. The passages can be arranged in a side-by-side configuration, and include pressure and return lines such as used to drive a hydraulic motor connected to the gear pump. The modular pipe assemblies can have two, three, four, or more passages, and can be stepped relative to each other to give a unique assembly orientation. The modular assemblies have mating fitting that can be tightened without the need to spin the pipe joints at the same time.
