Abstract: An oil well test burner provides for the use of a hollow body which defines a mixing chamber therein. A plurality of openings are formed in the body in communication with interior chamber for delivering oil and air into the interior chamber in such a manner, that an opening delivering oil into the chamber is disposed diametrically opposite at least one other opening which delivers air into the chamber. A pair of manifolds delivers oil and air, respectively, through a plurality of a corresponding number of emanating conduits which are attached to the body in a surrounding relationship to a respective opening in the body. Each manifold is provided with a flow regulating valve downstream from the conduits.

Abstract: A flow choke filter for use with oil and gas wells wherein the flow choke has a sized passage for restricting fluid flow from a well and is seated in a housing that has an inlet for conducting well fluids to the inlet of the sized passage and an outlet for discharging well fluids from the flow choke sized passage and the housing, said filter having an elongated hollow body which is closed at one end and open at the other end. The hollow body is provided with an exterior surface in which recesses are formed with a longitudinally extending space between the recesses, such longitudinal space forming a surface between each recess which projects outwardly relative to the recesses in the body. A plurality of openings are provided in the bottom of the recesses for receiving flow from the well and conducting into the hollow body.
