Abstract
Abstract An apparatus for processing production fluid from an oil well in the field to obtain clean power oil for a fluid operated pump in the well. The apparatus is intended to service a single well, or at most a few wells, and includes components for removing solids, gas and water from the production fluid to obtain the clean power oil, which is pressurized by a triplex pump and delivered to the fluid operated pump in the well. The apparatus also includes a storage tank containing a sufficient reserve of clean power oil for circulating the fluid operated pump into and out of the well. A circulating pump having a capacity about twice that of the triplex pump continuously circulates the clean oil in the storage tank through parallel cyclones which remove any residual solids.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
221 words
An apparatus for processing production fluid from an oil well in the field to obtain clean power oil for a fluid operated pump in the well, including: a. a production fluid inlet for production fluid from the well; b. a production fluid outlet connectible to a point of production fluid disposal; c. a power oil outlet connectible to the fluid operated pump in the well; d. a primary cyclone having an inlet connected to said production fluid inlet, having a gas outlet and a solids outlet connected to said production fluid outlet, and having a clean fluid outlet; f. a three phase separator connected to said clean fluid outlet of said primary cyclone, said separator having gas and water outlets connected to said production fluid outlet and having a clean oil outlet; g. a storage tank connected to said clean oil outlet of said separator; h. a secondary cyclone having an oil inlet, an oil outlet and a solids outlet, the latter being connected to said production fluid outlet; i. a circulating pump having an inlet connected to said storage tank, and having an outlet connected to said oil inlet of said secondary cyclone; and j. a triplex pump having an inlet connected to said oil outlet of said secondary cyclone, and having an outlet connected to said power oil outlet.
Claim 2
Independent Claim
