摘要： Downhole drilling vibration analysis uses an angular rate sensor on a drilling assembly. During drilling operations, the sensor measures the angular rate of the drilling assembly. Processing circuitry is operatively coupled to the angular rate sensor and is configured to determine whether torsional type vibrations are occurring during drilling based on the angular rate data. Drilling operations can then be modified to overcome or mitigate the torsional type vibrations.

摘要： A drill collar assembly (120) allows a sensor (150) to be mounted with the same standoff from a borehole wall independent of the size of stabilizer and borehole involved. A sensor component disposes in a receptacle (124) in the drill collar, but does not affix in the receptacle. Instead, a stabilizer (130) fits on the drill collar (120) and covers the receptacle (124), and the sensor component (150) mounts directly to the underside of the stabilizer (130) so the component "floats" or "suspends" in the receptacle. The sensor component (150) can mount at a stabilizer blade (132) so the sensor can be positioned in closer proximity to the borehole wall to measure parameters of interest. Because the drill collar (120) and sensor component (150) can be used in different sized boreholes, different sized stabilizers (130) may be positioned on the drill collar to account for the different sized boreholes while the sensor (150) still has the same standoff.
摘要翻译：钻铤组件（120）允许传感器（150）以与井眼壁相同的支座安装，而与所涉及的稳定器和钻孔的尺寸无关。传感器部件布置在钻铤的接收器（124）中，但不附接在接收器中。取而代之的是，稳定器（130）装配在钻铤（120）上并覆盖容器（124），并且传感器部件（150）直接安装到稳定器（130）的下侧，使得部件“浮动”或“悬挂 “在容器中。传感器组件（150）可以安装在稳定器叶片（132）处，使得传感器可以更靠近井壁定位以测量感兴趣的参数。因为钻铤120和传感器部件150可以用于不同尺寸的钻孔中，所以不同尺寸的稳定器130可以定位在钻铤上以解决不同尺寸的钻孔，而传感器150仍然具有同样的僵局。

摘要： A reservoir evaluation system (100) enables end users (200) to plan jobs for performing formation tests at remote wellsites. In the planning, the end user defines the toolstring to be constructed at the remote wellsite by service personnel and defines the details for the formation tests to performed with the toolstring. While the tests are performed, the system (150) obtains data via a satellite (140) or other communication link with the remote wellsite (110) and stores the data for retrieval and processing. The data measured from the formation tests conducted with the toolstring can be obtained in real time from the wellsite. The system processes the obtained data to produce analysis for the end user, who can then remotely access the data and analysis with a secure network connection (190) via the Internet or the like.

摘要： In an underbalanced drilling system and method, a change is induced in flowing bottom hole pressure in a wellbore. Data of the surface flow rate of effluent is then measured in response to the induced change. This measured data is obtained using a multi-phase flow meter before a separator of the underbalanced drilling system. Algorithms in computer software analyze the flowing bottomhole pressure and the measured surface flow rate data and determine both permeability and formation pressure for a portion of the wellbore in real-time during the underbalanced drilling operation. Ultimately, portion of the wellbore is characterized with the determined permeability and formation pressure.
