摘要： A method for drilling and a surface steerable system for use with a drilling rig are described, wherein the method comprises:
receiving, by a surface steerable system coupled to a drilling rig, bottom hole assembly (BHA) information associated with a rotary steerable BHA at a first location in a borehole, wherein the rotary steerable BHA further comprises a pad on an exterior surface of the rotary steerable BHA or a bent main shaft;
receiving, by the surface steerable system, geological information associated with a geological formation through which the borehole extends;
calculating, by the surface steerable system, forecasted information including torsional and spatial forces that are predicted to act on a drill bit attached to the rotary steerable BHA, wherein the torsional and spatial forces are predicted to be caused by actuator forces associated with the pad or the bent main shaft, and wherein the forecasted information is calculated using the BHA information and the geological information;
calculating, by the surface steerable system, a first vector representing a convergence path from the first location of the rotary steerable BHA to a target drilling path based on the forecasted information;
causing, by the surface steerable system, at least one drilling parameter to be modified in order to enable drilling using the rotary steerable BHA according to the first vector, wherein the drilling rig is enabled for the drilling according to the at least one drilling parameter using the rotary steerable BHA; and drilling the borehole using the rotary steerable BHA according to the at least one drilling parameter.

摘要： A method (100) of enabling at surface orientation data transfer from a contactless orientation system (11) coupled with an inner core tube (12) to one or more record carriers on or associated with a core sample (14) held in the core tube, the core sample (14) having a longitudinal core axis (16) and a core face 18 accessible from an end of the inner core tube (14), involves three broad steps. A first step is to couple an instrument guide (20) to the end of the core tube (12) from which the core face (18) is accessible so that an axis (26) of the guide is parallel to the core axis (16). A second step is to generate correlation information between a rotational orientation of a known point P on the instrument guide (20) or an instrument (28a) supported by the instrument guide (20) about the guide axis (26) and core orientation data known to the contactless orientation system (11). A third step is to use or otherwise operate the instrument (28a) to: act as the record carrier; or generate the record carrier provided with the correlation information enabling orientation of the core sample (14) to its in-situ orientation when released from the core tube (12).

摘要： Adjustable drill string housings are described for use in the directional drilling of wellbores, e.g. wellbores for hydrocarbon recovery wells. The adjustable drill string housings permit adjustment of a bend angle in the housings without removing the housings from a wellbore. In some exemplary embodiments, the bend angle can be adjusted by changing the internal stresses in a support member carried by the housings. In other embodiments, the bend angle may be adjusted by causing failure of sacrificial support members carried by the housings, and the failure may be caused by delivering chemicals through a chemical delivery system to the sacrificial support members. Methods of operating the adjustable drill string housings include multi-lateral drilling operations wherein the bend angle is adjusted when a casing window has been detected.

摘要： A surface excitation ranging method includes selecting a first well with a metal casing as a target well and selecting a second well with a metal casing as a ground well. The method also includes installing a supplemental grounding arrangement for a power supply located at earth's surface, wherein the ground well and the supplemental grounding arrangement fulfill an impedance criteria or ranging performance criteria. The method also includes conveying an electrical current output from the power supply along the target well. The method also includes sensing electromagnetic (EM) fields emitted from the target well due to the electrical current. The method also includes using distance or direction information obtained from the sensed EM fields to guide drilling of a new well relative to the target well.
