    Abstract: Downhole flow control valves (120) include a valve assembly (130), driven gear (180), drive gear (182), and motor (10')· The valve assembly includes an outer sleeve (140) and inner sleeve (160). The outer sleeve has openings (146) and a fixed guide (150). The inner sleeve is disposed within the outer sleeve and includes an outer surface (162) and an axially abutting surface (170) defining a stair-stepped pathway (172). The fixed guide abuts against the axially abutting surface. The abutment of the fixed guide against the axially abutting surface of the inner sleeve causes the inner sleeve to translate axially between an open position and a closed position relative to the outer sleeve when rotated through operation of the motor, drive gear and driven gear. Systems (300) for controlling fluid flow from lateral branches (112) of a multilateral wellbore (100) include at least a plurality of the downhole flow control valves and a downhole electrical power source (124) for generating electrical power to operate the motor.

    Abstract: A method for reservoir simulation is disclosed. The method includes selecting a coarse grid size (300) for a plurality of grid blocks in a reservoir model of a reservoir, computing, by a computer processor and based at least on a fractional flow curve of oil and water, a water saturation at a water front within a grid block of the plurality of grid blocks and an average water saturation of the grid block (302, 304), and computing, by the computer processor and based at least on the water saturation at the water front within the grid block and the average water saturation of the grid block, a water saturation distribution in the reservoir by solving reservoir simulator equations (308), wherein solving the reservoir simulator equations comprises computing a single water saturation value for each of the plurality of grid blocks based on the coarse grid size.

    Abstract: Systems and methods include a computer-implemented method: Real-time measurements are received by a wellhead growth monitoring computer system from a sensor on a wellhead of a well. The sensor is directed to a fixed point on a platform grating that is facing or underneath the wellhead. The real-time measurements, including measurements of a distance from the sensor to the fixed point, are analyzed by the wellhead growth monitoring computer system, including comparing the real-time measurements to previously-received measurements from the sensor. A determination is made, by the wellhead growth monitoring computer system based on the analyzing, that wellhead growth of a wellhead structure of the well has occurred. The wellhead growth is a vertical elongation of the wellhead structure. A notification that is provided to a user includes a measure of the wellhead growth and a time at which the wellhead growth occurred.

    Abstract: The foundation construction machine (1) comprises a self-moving or mobile assembly (2) configured to move on the ground, thus moving the foundation construction machine (1); an upper structure (3), mechanically connected to said self- moving or mobile assembly (2), said upper structure (3) being equipped with at least one predefined access point (3A, 3B, 3D) configured to allow a person to gain access to said upper structure (3), and being equipped with at least one walkway surface (7, 16, 18, 21), whereon a person accessing the upper structure (3) will be able to stand or walk. A mast or boom (4) is mechanically connected to the upper structure (3), whereon an operating equipment (5) is configured to be mounted in order to drill the ground. At least one presence sensor (20) is integrally mounted to the upper structure (3), so oriented and configured as to monitor a monitoring region integral with said upper structure (3) and covering said at least one walkway surface (7, 16, 18, 21), said at least one presence sensor (20) being configured for detecting the presence of a solid body in said monitoring region and for sending a detection signal representative of the presence of said solid body. A control system (9) is operationally connected to said at least one presence sensor (20), and is configured for receiving said detection signal from said at least one presence sensor (20) and for sending at least one control signal intended to cause said foundation construction machine (1) to execute at least one predetermined function when said detection signal is representative of the presence of a solid body situated in proximity to said at least one walkway surface (7, 16, 18, 21).

    Abstract: A system for identifying migration direction of natural gases is provided and may include a network of 4He gas sensors and a migration monitoring hub. The network of 4He gas sensors may be operable to identify a 4He concentration in gas samples. The migration monitoring hub may be in communication with the network of 4He gas sensors and may comprise a user interface and a processor. The processor may be operable to determine a direction of increasing 4He concentration and map increasing 4He concentration. The user interface may be operable to display migration information. A method for identifying migration direction of natural gases is also provided and may include isolating a target portion of a petroleum exploration environment, detecting gas samples from a network of 4He gas sensors, identifying a 4He concentration in the gas samples, and determining a direction of increasing 4He concentration in the gas samples.
