Abstract: A system includes a controller and a system of valves connected to pipes collecting the well casing gas produced from a casing annulus of the producing well. A pressure sensor measures the pressure of the well casing gas in the casing annulus. The system determines a well casing gas flow rate by measuring a build-up pressure of the well casing gas in a casing annulus when a valve from the casing annulus is closed. A fluid level in the casing of the well is determined using a pressure wave created in the well casing gas using the controller and the one or more valves. A fluid gradient correction factor is found using an actual fluid level in the casing. The controller calculates the pressure using the gas flow rate, the fluid level and the fluid gradient correction factor.

Abstract: A plunger lift system includes a bumper assembly to reduce the impact of the plunger at the bottom of the well and in some circumstances to reconfigure the plunger for the plunger's next ascent. The bumper assembly has a spring, a mandrel, an impact head, and a flow cage. The impact head and mandrel are constructed from a single piece of material thereby removing a joint between the impact head and mandrel. The unitary impact head/mandrel is connected to the flow cage using a first cooperating shoulder at the lower end of the unitary impact head/mandrel and a second cooperating shoulder within the flow cage. The first cooperating shoulder and the second cooperating shoulder are held in place with respect to each other by a force provided by the spring.

Abstract: A gas lift system may be installed within a well to allow gas lift operations where gas may be injected into the annular area of the well while producing fluids through the interior of the production tubular or upon demand may be reversed so that gas may be injected into the interior of the production tubular while producing fluids to the annular region of the well. In order to allow bidirectional production on demand two types of gas lift mandrels are installed as part of the production tubular. Both types of gas lift mandrels are configured such that gas lift valves are mounted to the exterior of the mandrels. In order to facilitate the desired direction of gas flow through the two types of gas lift mandrels a plug and packer system with or with out one way valves may be utilized to direct and contain the pressurized gas flow within the well.

Abstract: Gas is injected into the interior of the production string. The gas eventually reaches a gas lift mandrel that provides access from the interior of the gas lift mandrel to a chamber on the exterior of the gas lift mandrel. The chamber includes a cap that provides gas access between the interior of the chamber and the annulus. However, the cap is fitted with a gas lift valve and a check valve that regulates the gas flow into the fluid.

Abstract: The present invention relates to a device and method for injecting high pressure gas into a production tubular. As the gas flows down the production tubular the gas will reach a mandrel having a port through a side of the mandrel that allows the gas to flow from the interior of the mandrel to the exterior the mandrel. Generally, on the exterior of the mandrel a fitting is attached that further allows a small tube to be attached to the fitting. The fitting allows the gas flowing from the interior of mandrel through the fitting to flow into the interior of the small tube. Generally, a threaded cap is attached to the far end of the tube so that a check valve can be threaded into the cap and a conventional gas lift valve is then threaded into the check valve. The check valve and gas lift valve are then inserted into the small tube such that the threaded cap is screwed into the small tube sealing the small tube.
