    • Multi-array laterolog tool systems and methods acquire a set of array measurements sufficient to provide laterolog tool measurements of differing array sizes. Such systems and method offer multiple depths of investigation while offering greater measurement stability in borehole environments having high resistivity contrasts. In at least some system embodiments, a wireline or LWD tool body has a center electrode positioned between multiple pairs of guard electrodes and a pair of return electrodes. The tool's electronics provide a current from the center electrode to the pair of return electrodes and currents from each pair of guard electrodes to the pair of return electrodes. Each of the currents may be distinguishable by frequency or distinguishable by some other means. This novel arrangement of currents provides a complete set of measurements that enables one tool to simultaneously emulate a whole range of laterolog tools.
    • 多阵列后验工具系统和方法获取足够的阵列测量集,以提供不同阵列大小的后者工具测量。 这种系统和方法提供多个调查深度,同时在具有高电阻率对比度的钻孔环境中提供更大的测量稳定性。 在至少一些系统实施例中,有线或LWD工具主体具有位于多对保护电极和一对返回电极之间的中心电极。 工具的电子器件提供从中心电极到一对返回电极的电流以及从每对保护电极到一对返回电极的电流。 每个电流可以通过频率区分或通过某种其他方式可区分。 这种新颖的电流布置提供了一整套测量,使一个工具能够同时模拟一整套后期工具。

    • An automated, self-adaptive framework prioritizes software testing in a consistent and effective manner. A metric evaluates past test execution information for assigning regression testing priority. The metric may be calculated with reference to one or more of the following factors taken in combination: requirement, coverage, history, and cost. The requirement factor considers customer-assigned priority of testing the code, complexity of implementing the code, and proneness of the code to faults. The coverage factor considers code coverage, feature coverage, and common usage rate. The history factor considers previous bug found rate, case stable rate, and priority to calculate. The cost factor considers test case execution time, and step length. A value of each factor for one test case is measured according to that test case and is not related to other test cases. The calculation result representing the metric for each test case determines a priority of the test case.
    • 自动化的自适应框架以一致和有效的方式优先考虑软件测试。 指标评估过去的测试执行信息,以分配回归测试优先级。 可以参考以下组合中的一个或多个因素来计算度量:要求,覆盖率,历史和成本。 要求因素考虑了客户分配的测试代码的优先级,实现代码的复杂性和代码的错误。 覆盖率考虑代码覆盖率,功能覆盖率和常用使用率。 历史因素考虑以前的错误发现率,病例稳定率和优先级来计算。 成本因素考虑测试用例执行时间和步长。 一个测试用例的每个因子的值根据该测试用例进行测量,与其他测试用例无关。 表示每个测试用例的度量的计算结果决定了测试用例的优先级。

    • A method for performing detection of a bed boundary can include deploying a tool body with a longitudinal axis in a borehole, modulating the magnetic moments of electromagnetic signals to be transmitted by the first transmitter and the second transmitter, firing the first transmitter and the second transmitter substantially simultaneously, utilizing the receiver to receive and measure the modulated electromagnetic signals from the first transmitter and the second transmitter, and computing the orientation and location of the bed boundary based on the amplitudes and phases of the electromagnetic signals received and measured at the receiver. The tool body can be deployed with a first transmitter, a second transmitter, and a receiver, all of which are oriented in different directions. The vector of the total magnetic moment of the modulated electromagnetic signals can electrically rotate during firing. A corresponding apparatus for detection of a bed boundary is also provided.
