  • Patent number: 11306582
    Abstract: Inversion-based workflows are provided for real-time interpretation of the electromagnetic (EM) look-around and look-ahead measurements. The profile of a look-around zone is determined by interpreting EM measurements of a look-around zone. The profile of the look-around zone characterizes formation dip as well as vertical resistivity or resistivity anisotropy of one or more formation layers of the look-around zone. The profile of a look-ahead zone is determined by interpreting EM measurements of the look-ahead zone. The profile of the look-ahead zone characterizes formation dip as well as horizontal resistivity, vertical resistivity or anisotropy of one or more formation layers of the look-ahead zone. The workflows can also involve interpretation of look-around resistivity measurements to aid in the characterization of the look-around zone.

    Abstract: There is provided herein a system and method for automatically determining a path within a target rock unit of a directionally drilled well (a target well) using log readings, e.g., gamma log readings, taken in the target well as compared with log readings (a typelog) taken in a well that penetrates the target rock unit (an offset well). Most specifically, in some embodiments the path of the target well within the target rock unit will be obtained by solving a minimum travel distance problem which uses distances that are based on differences between well log readings in the target and offset wells. Solution of this problem will yield a collection of stratigraphic blocks lengths and dips that define a path of a well in a subsurface through the target formation or rock unit.

  • Patent number: 11047224
    Abstract: A system and method are used in drilling a borehole in a formation. A trip to move a drillstring in the borehole is identified, where the trip is expected to produce a piston effect that changes a downhole pressure of the fluid in the borehole. A peak speed to move the drillstring in the borehole is calculated for the trip, and adjustments to a surface backpressure of the drilling system is calculated for the trip at the calculated peak speed to keep the downhole pressure within a tolerance of the formation. The drillstring is moved in the trip according to the calculated peak speed, and the downhole pressure change produced by the piston effect is counteracted by automatically adjusting the surface backpressure according to the calculated adjustments.

  • Patent number: 10895145
    Abstract: A boring tool that is moved by a drill string to form an underground bore. A transmitter transmits a time varying dipole field as a homing field from the boring tool. A pitch sensor detects a pitch orientation of the boring tool. A homing receiver is positionable at a target location for detecting the homing field to produce a set of flux measurements. A processing arrangement uses the pitch orientation and flux measurements with a determined length of the drill string to determine a vertical homing command for use in controlling depth in directing the boring tool to the target location such that the vertical homing command is generated with a particular accuracy at a given range between the transmitter and the homing receiver and which would otherwise be generated with the particular accuracy for a standard range, different from the particular range. An associated system and method are described.

  • Patent number: 10883360
    Abstract: A disclosed borehole curvature logging system includes: a drill string having a bottomhole assembly (BHA) with sensors providing actual deformation and bending moment measurements as a function of BHA position at spaced-apart intervals on the BHA; a processing system that retrieves said actual measurements and responsively generates a log of borehole curvature; and a user interface that displays the borehole curvature log. The processing system implements a method that generates the log by: providing an estimated borehole trajectory; deriving predicted deformation and bending moment measurements based on the estimated borehole trajectory; determining an error between the predicted measurements and the actual measurements; updating the estimated borehole trajectory to reduce the error; repeating said deriving, determining, and updating to refine the estimated borehole trajectory; and converting the estimated borehole trajectory into a borehole curvature log.

  • Patent number: 10871065
    Abstract: A method for the identification of the position of a first well, modelled by a distribution of poles, includes, after having determined an optimum position of each pole, determining a three-dimensional region of uncertainties around the optimum position of each pole, by applying a numerical method characterizing the differences between at least one measurement of the magnetic field and a disturbed theoretical magnetic field by varying the position of at least one pole and comparing a result of the numerical method with a threshold value. If the result is less than or equal to the threshold value, the disturbed position of the pole is considered in the region. The region is thus defined with a centre corresponding to the optimum position of the pole and the radii of which have a length at least equal to the maximum difference between the acceptable positions of the poles and the optimum position.

The reference field sensor provides a reference sensor signal in response to a field, and a calibrated field sensor biased with an individually adjustable current and providing a calibrated sensor signal in response to the field. A control circuit controls the adjustable current bias of the calibrated field sensor at a calibrated current different from the reference current so that the calibrated field sensor provides a calibrated sensor signal substantially equal to the reference sensor signal in response to a common field. The field sensor device is arranged to be exposed, when in a calibration mode, to a uniform calibration field and, when in operational mode, to an operational field being a field gradient.
