Mark H. LOWE - Odessa TX, US

International Classification:

E21B 34/08
E21B 43/38
E21B 43/12

Abstract:

A gas vent tool can include a body with a flow passage having upstream and downstream sections, a valve that selectively permits and blocks flow between the upstream section and an exterior of the gas vent tool, and a valve that selectively permits and blocks flow between the upstream and downstream sections. A gas vent system can include a gas vent tool connected longitudinally between an intake tool and a pump, the intake tool being configured to receive formation fluids therein, and the pump being configured to pump the formation fluids to surface. The gas vent tool can include a valve that selectively permits and blocks flow between an interior flow passage and an annulus external to the gas vent tool, and a valve that selectively permits and blocks flow between upper and lower sections of the flow passage.

Abstract:

A filter bypass tool for use in a subterranean well can include an inner tube having a flow passage extending longitudinally through the inner tube, a pipe surrounding the inner tube, with an annulus formed radially between the pipe and the inner tube, the pipe being perforated to permit fluid communication between the annulus and an exterior of the pipe, and a bypass valve having closed and open configurations. In the closed configuration the bypass valve blocks fluid flow from the annulus to the flow passage. In the open configuration the bypass valve permits fluid flow from the annulus to the flow passage. The bypass valve is configured to open in response to a predetermined pressure differential from the annulus to the flow passage.

International Classification:

E21B 34/12

Abstract:

A chemical treatment assembly can include a section including a pressure containment valve that selectively permits and prevents fluid communication with a flow passage in the section, and another section including a pressure containment valve that selectively permits and prevents fluid communication with a flow passage in the section. The pressure containment valves are closed in response to disconnection of the sections. A method of containing pressure in sections of a chemical treatment assembly can include installing a pressure containment valve in each of the sections, the pressure containment valves being configured to close in response to disconnecting the sections. Another chemical treatment assembly can include an outer housing, a flow passage extending longitudinally through the outer housing, a chemical treatment positioned in the flow passage, and a pressure containment valve that selectively permits and prevents fluid communication with the flow passage through the pressure containment valve.
