    摘要： Systems, devices and methods for determining a parameter of interest of a well fluid relating to a well intersecting a subterranean formation using resonant vibration. The apparatus may include a resonator assembly. The resonator assembly may comprise a plurality of resonant tines structurally coupled to behave as a single resonator. At least one resonant tine of the plurality of resonant tines may include a soft magnetic tine head comprising soft magnetic material uncontained by a supporting surface. Each corresponding tine of the plurality of resonant tines may be formed by at least the resonant tine head and a tine shaft. Each corresponding tine may have a cross section perpendicular to a longitudinal axis of the corresponding tine, the cross section including a tine head, where the cross section has a substantially continuous material composition. Each tine shaft may terminate at the tine head.

    摘要： An apparatus for estimating gravitational properties includes an optical source, a first interferometer including a fixed reference reflector and a first reflector coupled to a first moveable mass, a second interferometer including the fixed reference reflector and a second reflector coupled to a second moveable mass, a first detector configured to detect a first interference pattern generated by the first interferometer, and a second detector configured to detect a second interference pattern generated by the second interferometer. The first mass is configured to move a first amount in response to a change in gravitational force, and the second mass is configured to move a second amount in response to a change in gravitational force, the second amount being smaller than the first amount. The apparatus also includes a processor configured to estimate the change in gravitational force based on a combination of the first and second interference patterns.

    摘要： A method implemented by a processor for drilling a borehole includes: inputting drilling parameters used to drill one or more offset boreholes, rate of penetration for the one or more offset boreholes, and one or more lithologies for the one or more offset boreholes; identifying those drilling parameters that correspond to a rate of penetration (ROP) that meets or exceeds a selected ROP threshold for each input lithology; correlating a borehole plan comprising a borehole path to be drilled and one or more assumed lithologies as a function of depth to the one or more lithologies of the one or more offset boreholes; sending the identified drilling parameters to a drill rig controller for each of the assumed lithologies in the borehole plan; and drilling the borehole with the drill rig using the identified drilling parameters for each of the one or more assumed lithologies in the borehole plan.

    摘要： A high-strength meshed bag with a ring fits into a seat between downhole or surface connections in a conduit or into a dedicated filter sub assembly. The filter filters a flowing fluid inside the conduit. The bag may be formed of aramid fibers with a molded ring. The bag may have varying mesh properties along its surface. There may be several mesh layers in the bag. The conduit may include surface pipes, hoses, surface fluid handling equipment, a drill string, or production string. The bag may be designed to let drop balls through when desired while catching much smaller particles otherwise.
