摘要： A drill bit assembly includes a drill bit body, an insulating layer disposed on an end of the drill bit body and that defines a drill bit face and two electrodes formed such that they both extend from the drill bit face. The two electrodes form a spiral on the drill bit face and are equidistant from each other at all locations of the drill bit face.

摘要： A method for drilling a borehole penetrating an earth formation includes: drilling a first section of the borehole; notching a wall of the borehole in one or more selected locations with a selected type of notch using a notcher for defined local weakening of the formation; performing a local induced break-out test and/or local fracturing operation on an annulus section of the first section of the borehole between the drill string and a wall of the borehole using a test tool comprising a packer to provide formation stress-state data. The one or more locations is based on the formation stress-state data. The method further incudes deriving stress-state of the formation and a fracturing parameter of the formation using the formation stress-state data and drilling a second section of the borehole using the derived stress-state and the fracturing parameter.

摘要： A system for performing a wellbore operation while a fluid circulates in a wellbore may include a string, a fluid circulation system, a control device, The string may include at least a first tubular section and a second tubular section. Thea fluid circulating system has a first fluid path and a second fluid path, wherein only one of the first fluid path and the second fluid path circulate the fluid into the string at a specified time. The control device selects one of the first or second fluid path through which to convey the fluid into the string, at least one signal generator in hydraulic communication with the circulating fluid, the at least one signal generator configured to impart at least one pressure signal into the circulating fluid, and at least one pressure transducer in pressure communication with the circulating fluid and configured to detect the imparted at least one pressure signal, wherein the at least one signal generator and the at least one pressure transducer form a communication link, the communication link configured to convey information between at least two locations along a flow path of the circulating drilling fluid, irrespective of the fluid path selected by the control device to convey the fluid into the drill string.

摘要： A string to be expanded is run in with a running string that supports a swage assembly. The running string is secured to the existing tubular and the top of the string to be expanded is sealed around the supported running string. The pressure applied to the annular space above the seal drives the liner over the swage. A cement shoe is affixed to the lower end of the string that is expanded after becoming detached from the running string assembly. When the expanded liner bottoms on a support, generally the hole bottom, the cement is delivered through the shoe and the expansion of the top of the string into a recess of the string above continues. The swage assembly with the seal and the anchor are then recovered as the running string is removed during the process of expanding the top of the expanded string into the lower end recess of the existing string already in the wellbore.
