Abstract: A vortex flow meter is within a flow conduit. The vortex flow meter includes a housing defining a flow passage substantially in-line with the flow conduit. An actuable buff body is within the flow passage. A sensor is downstream of the actuable buff body and is attached to the housing. The sensor is configured to detect vortex shedding. A controller is configured to send a drive signal to an oscillator to oscillate the buff body. The controller is configured to receive a vortex stream from the sensor. The vortex stream is indicative of vortexes shed by the buff body within a fluid. The controller is configured to determine a flow velocity responsive to the received vortex stream.

Abstract: A method includes spraying acid onto an inner wall of a wellbore formed in a subterranean zone with entrapped hydrocarbons that flow into the subterranean zone. Spraying the acid forms a subterranean cavern within a portion of the wellbore, the subterranean cavern being wider than the wellbore. The entrapped hydrocarbons flow into the subterranean cavern. The entrapped hydrocarbons include liquid hydrocarbons and water. The liquid hydrocarbons and the water separate under gravity within the subterranean cavern. The method also includes drawing the liquid hydrocarbons from the subterranean cavern to a surface of the wellbore.

Abstract: A first fracturing fluid is pumped through a first wellbore at a first pressure. The first wellbore includes a first vertical section and horizontal section having a first end, intersecting from the first vertical section, and a distal end. A second fracturing fluid is pumped through a second wellbore at a second pressure simultaneously while the first fracturing fluid is pumped through the first wellbore. The second wellbore includes a second vertical section that intersects with the distal end of the horizontal section. The first pressure and the second pressure result in the first fracturing fluid and the second fracturing fluid intersecting at a fracture point within the horizontal section at a third pressure. The first fracturing fluid and the second fracturing fluid each experience a respective pressure drop traveling through their respective wellbores to the fracture point/. The respective pressure drops result in the third pressure.

Abstract: An ultrasonic transceiver array provides for measurement and determination of flow rate of oil, water and gas in a multiphase flow in a pipe or conduit. The transceiver array is mounted externally and non-invasively in an elliptical arrangement on the pipe surface, resulting in an ellipsoid section of the flow cross-sectional area to be interrogated. The single ultrasonic transceiver array forms a tomographic image of multiphase flow to determine volume fraction of each phase; measure the total flow velocity to determine flow rate of individual phases and thus provide a three phase measurement capability. Both phase fractions and flow velocities can be determined at the same time, eliminating the need for two different systems to achieve that purpose.

Abstract: To prompt input and provide feedback on input to a user with an interface, inputs and graphical cursors associated with those inputs are defined. Each input may have several forms such as base, hover, engaged, completed, and error. User input is anticipated. The base form of the anticipated input cursor is displayed to prompt the user for the anticipated input. If user hover is detected that matches anticipated input, the hover form is displayed to confirm the match to the user. If user input is detected that matches anticipated input, the engaged form is displayed as confirmation. If user input is completed that matches anticipated input, the completed form is displayed as confirmation. If user hover or input does not match anticipated input, the error form is displayed to indicate mismatch. Not all cursors must have all forms, and some cursors may have multiples of some forms.
