摘要： A method includes disposing a tubular production string in a wellbore, the string having an upper portion with inner diameter greater than the inner diameter of a lower portion of the string. A tubular insert is disposed within the production string uphole of the lower portion. Opening an upper interval control valve (ICV) on the production string permits a flow of fluids from an upper production zone through the upper ICV to the surface through an interior annular volume formed by the exterior of the tubular insert and the interior of the upper portion, and opening a lower ICV on the production string permits a flow of fluids from a lower production zone through the lower ICV to the surface through the tubular insert, simultaneously and without commingling with fluids flowing through the upper ICV.

摘要： A variety of systems, methods and compositions are disclosed, including, in one method, a method for producing a subterranean formation, the method comprising: introducing a reactive material into a wellbore penetrating the subterranean formation; hydrolyzing the reactive material with an aqueous-based wellbore fluid to produce hydrogen gas; reducing a bulk density of the aqueous based wellbore fluid; producing the wellbore. A system for producing a wellbore, the system comprising: an oilfield tubular disposed in a producing wellbore; a fluid column comprising an aqueous based wellbore fluid within the oilfield tubular, wherein the fluid column comprises a hydrostatic head greater than a pore pressure of the wellbore; and a solid reactive material capable of chemically reacting with the aqueous-based wellbore fluid thereby reducing the hydrostatic head.

摘要： A method can include receiving a number of samples of liquid production values and associated gas-lift injection rates for one of one or more wells; determining a prospective optimal gas-lift injection rate for the one of the one or more wells via a regression that fits the number of samples; responsive to the prospective optimal gas-lift injection rate satisfying one or more gas-lift injection rate criteria, issuing an instruction to implement the prospective optimal gas-lift injection rate for the one of the one or more wells; receiving a new sample as a measured liquid production value for the implemented prospective optimal gas-lift injection rate and responsive to satisfaction of one or more compliance criteria; and replacing one of the number of samples with the new sample.

摘要： A method, related device and system for lifting a reservoir fluid in an oil and gas well involves allowing the reservoir fluid to flow in an axial uphole direction through an internal flow path of a production tubing disposed in the well. The internal flow path includes a Venturi profile configured to flash out a free gas phase from the reservoir fluid as the reservoir fluid flows in the axial uphole direction through the Venturi profile, such that the reservoir fluid comprises the free gas phase and a liquid phase. The internal flow path also includes a diffusion profile disposed above the Venturi profile and configured to condense the free gas phase into the liquid phase as the reservoir fluid flows in axial uphole direction through the diffusion profile.

摘要： A system for automatic in-situ gas lifting of fluid in a multilateral well may include a plurality of downhole sensors arranged to periodically capture pressure data associated with the multilateral well is disclosed. The system may include a processor operatively connected to the downhole sensors and configured to dynamically determine a pressure gradient value associated with the multilateral well based on the periodically captured pressure data. The system may include a first inflow control valve (ICV) operatively connected to the processor and placed within a first lateral to automatically control a flow of a gas from a downhole natural gas source into the multilateral well based on the dynamically determined pressure gradient, and to cause a lift of the fluid received from a second lateral within the well when the ICV is open.

摘要： A gas lift system for oil and gas wells has a gas pump. The gas pump comprises production tubing, a chamber, a dip tube, check valves, a gas supply line and control valve, a gas vent line and control valve, and a fluid control line. Liquid is pumped to the surface by allowing it to collect in the chamber and then forcing it out of the chamber with high-pressure gas. The gas supply and vent valves preferably are controlled by a single pressure control line. The system preferably included retrievable valves that may be installed through the production tubing to provide a life-of-the-well gas lift system.

摘要： A blower can be positioned in a wellbore. The blower rotatably drives or is driven by a fluid produced through the well bore. An electric machine can be positioned downhole of the blower, the electric machine configured to rotatably drive or be driven by the blower. A bearing shaft couples the blower and the electric machine. The bearing shaft transfers rotation between the blower and the electric machine. A passive magnetic radial bearing assembly magnetically supports the bearing shaft.
