摘要： Methods and apparatus for identifying downhole dynamics in a drilling system are provided. Acceleration-detecting sensors are mounted at multiple locations near to a drill bit, such as at a drill collar. The sensors may be spaced 90° apart along a circumference of the drill collar. The sensors detect acceleration measurements in a plane orthogonal to the drill string's axis of rotation, with respect to a first reference frame that moves with the drill string. The acceleration measurements are received by a processor and processed to determine rotational and revolution positions of the drill string within the wellbore with respect to a static reference frame. Whirl dynamics may, in particular, be determined based on the results in real time.

摘要： Systems and methods for diagnosis of a water source of a water production problem in a well include: measuring flow and water/oil ratio (WOR) of a fluid mixture produced from a well; accepting the measured flow and the WOR over a period of time; calculating the derivative in time of WOR (WOR′) over the period of time; accepting a selection of or making a comparison of the WOR or WOR′ over time to a particular WOR or WOR′ case history from a library of WOR and WOR′ case histories that correlate with various types of water sources in a library of potential water sources; accepting an additional type of information about the well selected from the group consisting of reservoir properties, completion history, production history, injection history, and interventions history; and weighting and scoring to suggest a diagnosis of a likely water source from the library of potential water sources.

摘要： A method and system for identifying bonding between a material and tubing. The method may include disposing an acoustic logging tool in a wellbore, wherein the acoustic logging tool comprises a transmitter, a receiver, or a transceiver, broadcasting a shaped signal with the transmitter such that the shaped signal interacts with a boundary of a casing and a material and recording a result signal from the boundary with the receiver. The method may further comprise identifying a cut-off time to be applied to the result signal, transforming the result signal from a time domain to a frequency domain, selecting one or more modes sensitive to a bonding at the boundary between the casing and the material, computing a decay rate of the one or more modes that were selected based at least one or more decay curves, and converting the decay rate to a bonding log.

摘要： Current profile of water (e.g., ocean) around a riser connected to a wellhead may be measured and used to determine integrated current load on the riser at any given moment in time. The integrated current load may be used to estimate the wellhead fatigue damage rate at that moment in time. The estimated wellhead fatigue damage rate may be used to make operational decisions for the well.

摘要： Example systems, devices, and methods are described for evaluating the relative leak safety of threaded connections in well tubulars. The method includes evaluating leak risk using a quadratic leak criterion, which is a function of the effective pressure (Pe) and includes three constants: a first constant called the leak path factor (δ), a thread modulus (α), and a makeup leak resistance (β). The method in some implementations includes identifying at least three test cases with different Δp expected to leak under certain conditions. The method includes fitting a quadratic expression to a subset of values associated with the leaking test cases, in which the resulting quadratic expression includes values for the three constants. The quadratic leak criterion can be expressed as a leak safety factor for evaluation of particular threaded connections, load cases, and conditions, thereby optimizing the design and selection of threaded connections and also optimizing connection performance during drilling and production operations.

摘要： A drilling system configured to reduce friction during slide drilling. The drilling system has a drill string comprising a fluid-driven drill stage such as a mud motor; a variable frequency drive configured to oscillate the drill string via a quill and a sensor array. The sensor array measures the torque applied to the quill and the angular position of the quill. A controller is used to control the variable frequency drive based on the determined applied torque and quill angular position to meet predetermined oscillation turn-around criteria and to reduce the time to reduce the angular velocity of the quill from a maximum rotational speed to zero in an oscillation cycle.

摘要： A method, apparatus and system for locating external apparatus mounted to a tubular in a wellbore. The identification of apparatus, such as cable clamps, enables other tools in the string to operate more precisely. A computer model is used to locate the apparatus from acoustic images, which images are acquired using a downhole device having an acoustic sensor or acoustic array. The model may be a classifier, which may be machine trained to classify whether an apparatus is present, its location and its orientation. Automating this locating enables very long wellbores to be processed quickly.
