摘要： A method and system for azimuthal direction detection of a cable. The method may comprise disposing an electromagnetic logging tool into a wellbore, transmitting a primary electromagnetic field from the one or more transmitters, recording one or more secondary electromagnetic fields at the one or more receivers, and identifying a direction to the cable from the one or more secondary electromagnetic fields. The system may comprise one or more transmitters disposed on the electromagnetic logging tool and configured to transmit a primary electromagnetic field. The system may further comprise one or more receivers disposed on the electromagnetic logging tool and configured to record one or more secondary electromagnetic fields. Additionally, the system may further comprise an information handling system configured to identify a direction to an azimuthally localized reduction in metal of the conductor or increase in the metal of the conductor from the secondary electromagnetic fields.

摘要： Methods and systems are described that can be used for locating conductive bodies such as wellbore casing or piping disposed below the earth's surface. An electrical current can be excited in a conductive body in each wellbore in a given area to produce a magnetic field, and the magnetic field can be detected by a ranging tool. Location and current parameters can be determined for an estimated number of wellbores producing non-negligible contributions to the magnetic field, and the estimated number of wellbores can be adjusted until the number of contributing wellbores is determined. Location solutions can be returned for each of the contributing wellbores, and the location solutions can be employed to facilitate exploration of drilling applications such as well avoidance, well intersection and/or steam assisted gravity drainage (SAGD) steering operations.

摘要： Disclosed embodiments include various borehole imaging tools and methods to provide sensing surface configurations for improving the assessment of anisotropy in layered formations. In at least some embodiments, the borehole imaging tools employ a unitary conductive body to provide a wall-contacting face with grooves that define multiple elongated sensing surfaces. This wall-contacting face can be provided on an extendable sensor pad of a wireline logging tool or embedded on the outer surface of a LWD stabilizer fin. Toroids may be seated in the grooves around each elongated sensing surface for measuring the current flow through each sensing surface. The elongated sensing surfaces can be arranged in pairs as a series of rectangular-shaped grooves that are aligned perpendicularly to each other within each of the pairs to improve detection of anisotropy in thin layered formations and improve the sensitivity to dipping in anisotropic formations.

摘要： A method and system for identifying a target well. A system for identifying a target well may comprise placing an electromagnetic ranging tool in a wellbore, transmitting an electromagnetic field into a formation, inducing an eddy current within a target well, measuring a second electromagnetic field from the target well, calculating a position or an orientation of a transmitter or a receiver relative to another position, and calculating at least one parameter of the target well. An electromagnetic ranging system may comprise an electromagnetic ranging tool and an information handling system. The information handling system may be operable to calculate a position and/or an orientation of a transmitter or a receiver relative to another position on the electromagnetic ranging tool disposed on a borehole assembly, and calculate at least one parameter of a target well from the calculated position or orientation of the transmitter and the receiver.

摘要： A method and electromagnetic ranging system for determining the location of a target well. A method may comprise taking a first measurement with an electromagnetic ranging tool at a first position and calculating a first modeled signal. Additionally, calculating a calibration for the electromagnetic ranging tool from at least the first measurement and the first modeled signal, taking a second measurement with the electromagnetic ranging tool at a second position, and calculating a calibrated measurement. The method may comprise determining a distance, direction, and/or orientation to a target wellbore using at least the calibrated measurement. An electromagnetic ranging system may comprise an electromagnetic ranging tool and an information handling system coupled to the electromagnetic ranging tool. The information handling system may be operable to calibrate the electromagnetic ranging tool, calculate a gain of the electromagnetic ranging tool, and apply the gain to a measured signal from the electromagnetic ranging tool.

摘要： Apparatus and methods are described, such as for obtaining formation parameters of a geological formation. The method includes measuring a resistivity image of the geological formation. The measured resistivity image is compared to a modelled resistivity image where the modelled resistivity image is represented by estimated formation parameters. A cost function is calculated from the measure resistivity image and the modelled resistivity image. The estimated formation parameters are adjusted to generate a set of final formation parameters that represents a modelled resistivity image having a smallest cost function.

摘要： A ranging system utilizes gradiometric data to determine the distance between a first and second well without any knowledge or involvement of the borehole or formation characteristics. In general, this is achieved by deploying a downhole assembly comprising transmitters and receivers having magnetic dipoles, along with bucking receivers positioned between the transmitters and receivers, wherein the gradient field is measured in a radial direction along the downhole assembly.
