摘要： A device for transporting a sensor assembly down a bore of a known diameter comprises a pair of wheels offset in a radial direction by a first radial distance from a longitudinal axis of the sensor assembly and at least one eccentric weight. The first radial distance and a lateral distance between the wheels and a diameter of the wheels configures the device so that, in use, a longitudinal axis of the sensor assembly is substantially coincident with a longitudinal axis of the bore when the wheels are in contact with a wall of the bore. The at least one eccentric weight is positioned so that a centre of mass of the combined device and sensor assembly is offset in the radial direction from the longitudinal axis of the sensor assembly by a second radial distance that is greater than the first radial distance to orient the device and sensor assembly by gravity in a most stable position with the rotational axis of the wheels and the centre of mass below the longitudinal axis of the sensor assembly with the wheels in contact with a low side of the wall of the bore.

摘要： A wellbore assembly can include a completion string having a side pocket. A downhole device can be positioned within the side pocket of the completion string. The downhole device can have a first end sized and shaped for coupling to a tool for inserting and removing the downhole device in the side pocket while the completion string is positioned downhole in a wellbore. The downhole device can be an electronic device.

摘要： A latching apparatus includes a body, a fin biased to protrude from the body, and a biasing element for so biasing the fin. A method for securing a tool in a drilling tubular includes connecting the tool to a latching apparatus, the latching apparatus including a fin biased to protrude radially outward, forcing the latching apparatus into the drilling tubular, and forcing the latching apparatus through a landing ring.

摘要： Methods, systems, devices, and products for taking multi-component induction tool measurements of a three-dimensional space from an interior of a plurality of nested tubulars in a borehole in an earth formation and estimating the property for each of the at least two tubulars using the multi-component induction tool measurements. The multicomponent induction tool measurements may be responsive to a property corresponding to at least two conductive tubulars of the plurality of nested tubular. Taking multi-component induction tool measurements may include taking three-dimensional low-frequency sinusoidal frequency domain waveform resistivity measurements and taking three-dimensional transient EM measurements with the multi-component induction tool.

摘要： A transmitter is powered by a regulated battery voltage and is installable in one of a plurality of different housings, each housing is characterized by a different design and each can form part of an inground tool for performing an inground operation in which a drill string extends from a drill rig to the inground tool. An antenna driver drives an antenna based on the regulated voltage to emanate an electromagnetic signal for remote reception. A controller limits power consumption from the regulated voltage so as not to exceed a power consumption threshold, irrespective of installation of the transmitter in any one of the housings when the transmitter would otherwise exhibit a different power consumption for each housing design. A corresponding method is described. Features relating to power consumption threshold modification based on temperature as well as mechanical shock and vibration are described.
