Abstract: A plunger for use in an oil or gas well that includes a mandrel and a hollow body with radial directed ports disposed therein. The plunger also includes a variable flow mechanism that can be adjusted to achieve a desired fall rate for the plunger for a particular oil and gas operation. A method of lifting fluids from an oil and gas well using the plunger includes the step of employing an adjustable plunger to lift fluids from the oil and gas well wherein the adjustable plunger has a desired fall rate in the well.

Abstract: A rod guide for guiding and protecting a sucker rod in a fluid mineral extraction setting. The rod guide comprising a bore shell, and a guide bore, a first end, a second end, one or more glue ports, a plurality of glue dams and a plurality of flutes. The bore shell wraps around the guide bore. The bore shell comprises an outside surface and an inside surface. The plurality of flutes are arranged around the bore shell extending outward from a central axis. The plurality of flutes are configured to prevent the sucker rod from rubbing within a tubing, as the sucker rod is inserted and withdrawn from said tubing the rod guide and the guide bore comprises the central axis.
