Abstract: A well unloading valve for a petrochemical well tubing comprising a flow passage connecting an annulus outside the tubing with the inside of the tubing; a lock-out sleeve for selectively closing the flow passage, wherein the lock-out sleeve can be moved from an open to a closed position by means of hydraulic pressure within the tubing; an electrically activated motor module for moving a seal, wherein the seal selectively opens a hydraulic connection from the inside of tubing to the lock-out sleeve for moving the lock-out sleeve hydraulically from the open to the closed position; and a check valve within the flow passage for allowing a flow from the annulus into the tubing and for blocking a flow from the tubing into the annulus. Further a method for unloading a petrochemical well tubing is claimed.

Abstract: Measuring the amount of individual gases in drilling fluids in real-time may be performed with optical computing devices that are calibrated in real-time or periodically with gas analysis devices to provide more accurate gas content measurements. In some instances, one or more drilling or completion parameters may be altered in response thereto the concentration or change in concentration of individual gases in drilling fluids.

Abstract: A drilling method includes collecting survey data at a drilling site, and determining a waypoint or borehole path based on the survey data. The drilling method also includes sending the survey data to a remote monitoring facility that applies corrections to the survey data. The drilling method also includes receiving the corrected survey data, and automatically updating the waypoint or borehole path based on the corrected survey data.
