    Abstract: A downhole tool includes a valve assembly and a shock absorbing assembly. The valve assembly includes a valve spring operatively connected to a valve body. The shock absorbing assembly includes a spring operatively connected to a shock absorbing body having a fluid passage therethrough. The valve body is configured to selectively engage the shock absorbing body to create a fluid tight seal over the fluid passage in a first position, and to allow a fluid flow through the fluid passage in a second position. The repeated movement cycle of the selective engagement between the valve body and the shock absorbing body generates a pressure pulse or a varying pressure differential across the downhole tool. The repeated movement cycle is powered by a fluid flow. The tool may be selectively activated and deactivated.

  • Patent number: 10408042
    Abstract: The invention discloses a series of methods to design drilling trajectory and control drilling operations in a optimized way in carbonate formation. The trajectory design method comprises: utilizing earthquake data to obtain contours of the carbonate rock fractures; determining a safe distance from each carbonate rock fracture; determining a segmented drilling trajectory for each fracture or vuggy structures in carbonate formation; and sequentially connecting the segmented drilling trajectories of neighboring fracture and vuggy to obtain a smooth horizontal drilling trajectory. The invention optimizes the carbonate rock reservoir drilling trajectory, thus improving connection between a horizontal well and the fractures. This reduces development costs, increases exploration and development efficiency and, at the same time, eliminates leaks resulting from the drilling process, thereby allowing for smooth drilling to a target well depth.

  • Patent number: 10400530
    Abstract: The present disclosure relates to systems, assemblies, and methods for facilitating fluid flow during/after landing of logging tools in a bottom hole assembly. In operation, a memory logging tool is lowered through a longitudinal bore of a drill pipe string and landed in a bottom hole assembly disposed at the end of the drill pipe string. Drilling fluid is pumped behind the logging tool to assist with downward movement of the tool. As the logging tools land, partial fluid flow path is blocked by the logging tools. The fluid pressure can rise in response to the narrowing of the fluid flow path. Facilitating fluid flow through and/or around the logging tools can put the rising fluid pressure in a proper range for powering the logging tools to land and monitoring purposes.

  • Patent number: 10180059
    Abstract: A telemetry tool comprising a pulser assembly, a primary seal, a fluid pressure pulse generator and a secondary seal. The pulser assembly comprises a housing and a driveshaft extending out of an opening in the housing. The primary seal surrounds and seals against the driveshaft to seal the opening in the housing. The fluid pressure pulse generator comprises a stator with a bore therethrough configured to fixedly attach to the housing or to a drill collar surrounding the fluid pressure pulse generator, and a rotor fixedly attached to the driveshaft. The driveshaft and rotor rotate relative to the fixed stator to generate pressure pulses in mud flowing through the fluid pressure pulse generator. The secondary seal is seated in the stator bore and surrounds and seals against a portion of the driveshaft extended out of the housing or a portion of the rotor to reduce the amount of mud, grit and debris impinging on the primary seal which could otherwise cause wear or damage the primary seal.

  • Patent number: 10161235
    Abstract: Well completion technology for resisting imbibing frack fluid into an inner surface of a frack comprises pumping a frack fluid into the wellbore to form a fracture in a formation surrounding a wellbore. In one example, formation of transverse micro-fractures extending transverse to the fracture is resisted to resist absorption of the frack fluid into the formation through the inner face of the fracture, or into existing transverse micro-fractures or transverse micro-fractures formed by the pumping of the frack fluid. In another example, a sealer is added to a frack fluid to sealing or coating an inner face of the fracture with the sealer. In another example, micro-particles with a size less than 100 microns are added to the frack fluid.

  • Patent number: 10145238
    Abstract: A magnetostrictive transducer system included as part of a drill string for use downhole in a well to convey signals across regions of the drill string that preclude the use of wired communication elements. The magnetostrictive transducer conveys a carrier signal as an acoustic wave through a drill collar region to an acoustic telemetry receiver, which passes an output both to an uphole processing system and back into the magnetostrictive transducer system. The output signal and carrier signal are compared to determine sub-harmonics or higher order harmonics of the output or carrier signal indicative of offset in the magnetostrictive core of the magnetostrictive transducer system, and provides a corrective component signal to automatically adjust the magnetostrictive core though preloading forces.

  • Patent number: 10116471
    Abstract: A transceiver and a corresponding method configured to recover within less than 1 ms from quality degradation in its operating point. The transceiver includes: a receiver analog front end (Rx AFE), an adaptive module comprising at least one of an adaptive digital equalizer and an adaptive digital canceller (ADEC), a common mode sensor AFE (CMS-AFE), a fast-adaptive mode-conversion canceller (FA-MCC), and a slicer. The Rx AFE receives signals from a second transceiver. Shortly after identifying quality degradation in the transceiver's operating point, the transceiver indicates the second transceiver to reduce the rate of the transmitted data. And within less than 1 ms, the transceiver utilizes the improved detection rate to improve the accuracy of the slicing errors, which enables fast adaptation of the ADEC, that improves the quality in the transceiver's operating point to a level that enables the transceiver to indicate the second transceiver to increase the rate.
