Abstract: An hydraulic packer assembly for sealing an annulus between a well casing and a tubing string inserted within the well casing comprises a packer (10) and a setting tool (12). The packer includes a packer body (22) having an internal bore (23) with a seal (18) and gripping members (20) mounted on its exterior surface for engaging the interior surface of the well casing. Actuating mechanisms are provided within the packer for expanding the seal and gripping members into contact with the casing wall, which mechanisms include a piston and cylinder arrangement operated by fluid pressure conveyed from the tool interior to the cylinder. The setting tool is releasably coupled to the packer body to mount it on a tubing string and for conveying fluid pressure to the actuating mechanisms. Seals on the setting tool provide a fluid tight seal between the setting tool and the axial bore through the packer body.

Abstract: A system for automatically controlling the intermittent pumping of a well minimizes fluid pound occurrence without reducing well production. The pump is operated in a learn mode until pump-off of the well when the pump is deactivated for a preset period. The pump is then operated in a control mode in which the pump is repeatedly cycled on to pump the well for at least one stroke less than the pumping time of the learn mode and then off for a preset period. Control mode operation is continued for a predetermined number of cycles after which the learn mode operation is repeated to reset the pumping time for the control mode operation.

The low heating value gas is preheated, mixed with an amount of air that will provide oxygen in an amount that will limit the maximum temperature rise in a catalytic combustion chamber to avoid excessive temperatures, and delivered into the catalytic combustion chamber at a temperature exceeding about 400.degree. F. that will cause ignition of the combustibles on contact with the catalyst. In a preferred embodiment, combustion is accomplished in two combustion chambers connected in series with a heat exchanger between the combustion chambers for cooling the combustion products discharged from the first combustion chamber before they are delivered to the next combustion chamber. Approximately fifty percent of the total combustion air is mixed with the combustible gas before delivery into each of the combustion chambers.
