    摘要: A wellbore instrument system includes a pipe string extending from earth's surface into a wellbore. At least a portion of the pipe string includes a signal communication channel having a cable, such as an electrical conductor or an optical fiber. At least one wireline configurable wellbore instrument is coupled to the pipe string and has at least one sensor therein for measuring a physical parameter. The at least one instrument is in signal communication with the signal communication channel in the pipe string. The system includes a controller functionally associated with the at least one instrument and configured to initiate operation of the at least one sensor upon detection of a command signal.

    摘要: A downhole formation fluid pumping and a sampling apparatus are disclosed that may form part of a formation evaluation while drilling tool or part of a tool pipe string. The operation of the pump is optimized based upon parameters generated from formation pressure test data as well as tool system data thereby ensuring optimum performance of the pump at higher speeds and with greater dependability. New pump designs for fluid sampling apparatuses for use in MWD systems are also disclosed.

    摘要: An apparatus and method includes releasably engaging a cementing tool in a casing assembly at a junction of plural wellbores. Cementing slurry is pumped through the cementing tool to fill an annular region around the casing assembly. The cementing tool is retrievable without first milling components at the junction. The cementing tool has an anchoring mechanism adapted to engage a landing profile of the casing assembly. Further, the cementing tool has an external seal adapted to seal inside the casing assembly.

    摘要: Examples of techniques for analyzing well data which may be encountered during formation testing are disclosed. Certain portions of the tests may exhibit an indication of anomalous behavior, defects, errors or events that may have occurred during testing. One or more confidence tokens may be identified during or after the execution of a test. One or more of these confidence tokens may be analyzed to determine whether such anomalous behavior, defects, errors or events have occurred during the test. These confidence tokens may then be used to determine a level of confidence in the results derived from the tests performed and/or their underlying data and interpretation.
