Abstract: A method may include generating (320) a first well intervention plan (260) for a well site automatically based on a predetermined scheduling criterion (261). The first well intervention plan (262) is generated using a first set of data inputs regarding one or more well intervention providers and one or more well conditions. The method may further include obtaining (305) first well data (263) regarding the well site. The method may further include adjusting (335) the predetermined scheduling criterion (261) to produce an adjusted scheduling criterion (412) using the first well data (263). The adjusted scheduling criterion (412) corresponds to a second set of data inputs that are different from the first set of data inputs. The method may further include generating (320) a second well intervention plan (262) for the well site based on the adjusted scheduling criterion (412). The method may further include transmitting (350) a command (295) to the well site that adjusts well operations based on the second well intervention plan (262).

Abstract: A system (200) for hybrid gas lifting may include a gas-lift completion arranged to inject high-pressure gas (210) into production tubing (204) of a well (102). The system (202) may include a downhole annular jet pump (226). The downhole annular jet pump (226) may include an annular nozzle (216) arranged to receive the injected high-pressure gas (210). The injected high-pressure gas (210) exits the annular nozzle (216) as an annular high-velocity gas jet. The downhole annular jet pump (226) may include a throat section (218) arranged to receive the annular high-velocity gas jet, and to mix the annular high-velocity gas jet with a low-pressure production fluid (214). The downhole annular jet pump (226) may include a diffuser section (220) arranged to facilitate conversion of kinetic energy into pressure energy in a mixture (222) of the annular high-velocity gas jet and the low-pressure production fluid (214), and to produce the mixture (222) to a surface via the production tubing (204).

Abstract: A current-mode Schmitt Trigger (200) includes a plurality of current output stages (201A-C) connected to a common supply voltage that powers the current-mode Schmitt Trigger, a main input on one of the current output stages (201a) that receives an input current (li), and a non-inverting output (lop) on a different one of the current output stages (201B) that is shorted to the main input (li) to establish a positive closed-loop feedback (If) and supplies a non-inverting output current (lop) as the input current. The current-mode Schmitt Trigger includes only active components.

Abstract: A terminal for performing Channel State Information (CSI) reporting for type II port selection codebook includes a receiver that receives beamformed CSI reference signal (RS) ports comprising spatial domain (SD) beams and frequency domain (FD) base. In addition, the terminal includes a processor that, using higher layer signaling, configures a number of SD beam selection and a number of FD base selection, and selects a first value from a first set of values for the number of SD beam selection and a second value from a second set of values for the number of FD base section. The terminal further includes a transmitter that transmits the first value and the second values.

Abstract: A method that includes transforming a relative amplitude preserved 3D seismic volume acquired in the time-domain into a plurality of isofrequency volumes, extracting from the plurality of isofrequency volumes a first isofrequency spectral amplitude volume and a second isofrequency spectral amplitude volume. The method further includes determining an attribute volume from the two isofrequency spectral amplitude volumes, and determining a presence of gas in a subterranean region of interest based on the attribute volume.

Abstract: An automated Back Pressure Valve (BPV) lubricator system includes a lubricator having a lubricator shaft terminated in a BPV lubricator connection; one or more hydraulic pistons attached to the lubricator; a hydraulic motor attached to the lubricator shaft; and a control panel hydraulically connected to the one or more hydraulic pistons and hydraulic motor. The hydraulic pistons, when actuated, raise or lower the lubricator shaft terminated in the BPV lubricator connection. The hydraulic motor, when rotated, rotate the lubricator shaft clockwise or counter-clockwise. The control panel allows actuation of the one or more hydraulic pistons and rotation of the hydraulic motor.

Abstract: An apparatus includes a drill bit having a frangible drive shaft, a thread cutting surface formed on an outer surface of the drill bit, a conical swage formed on the drill bit, the conical swage having a conical shape, and a seal plug coupled to the drill bit, the seal plug removable from the drill bit. A method includes penetrating an inner surface and an outer surface of the casing with a drill point of the drill bit thereby forming a hole, threadingly engaging the seal plug with the hole wall, disengaging the seal plug from a drive shaft of the drill bit assembly, retracting the drill bit assembly through the seal plug, and engaging an outer surface of a conical swage with an inner surface of the seal plug and radially expanding the seal plug as the conical swage is retracted through the hole wall, thereby sealing the hole.
