摘要： A method of drilling a borehole in an earth formation using a drill string including a control system for controlling the borehole trajectory. The control system is operable to receive a selected signal, to determine the borehole depth from at least one length increment and the number of times the selected signal is received, and to use the borehole depth as input parameter for controlling the borehole trajectory in correspondence with a desired borehole trajectory. While drilling, for each length increment that the drill string is lowered into the borehole, transmitting the selected signal to the control system; inducing the control system to determine the borehole depth from said length increment and the number of times the selected signal is received; and operating the control system to use the borehole depth as input parameter for controlling the borehole trajectory in correspondence with the desired borehole trajectory.

摘要： A logging system that may be used in a wellbore formed in an earth. A tubular conduit extends from surface into the wellbore and contains a body of wellbore fluid. A logging tool string may be passed from a position within the conduit to a position outside the conduit at a lower end part thereof, and may be suspended by the conduit in the position outside the conduit. A pressure pulse device is arranged within the conduit in a manner that the pressure pulse device is in data communication with the logging tool. The pressure pulse device is capable of generating pressure pulses in the body of wellbore fluid, which pressure pulses represent data communicated by the logging tool string to the pressure pulse device during logging of earth formation by the logging tool string. The system further includes a control system in fluid communication with the body of wellbore fluid and arranged to receive the pressure pulses.

摘要： A method of drilling a borehole into a subsurface earth formation, using a tubular drill string which includes at its lower end a bottom hole assembly comprising a drill bit, a drill steering system, and a surveying system. The drill string includes a selectively closable passageway for passing an auxiliary tool from a first position interior of the drill string above the bottom hole assembly to a second position. In the second position, at least part of the auxiliary tool is exterior of the drill string below the bottom hole assembly. The drill string is progressed into the earth formation by drilling. When a tool operating condition is met the passageway is opened and the auxiliary tool is passed through the passageway from the first position to the second position, where the auxiliary tool is operated.
