The present invention discloses a device for measuring dynamic evolution of a three-dimensional disturbed stress under mining disturbance, comprising an outer steel cylinder. Three three-direction sensing units are arranged on the outer steel cylinder. Any two of three stress measurement directions of each three-direction sensing unit are perpendicular to each other. Nine stress measurement directions of the three three-direction sensing units are different. The present invention also discloses a method for measuring dynamic evolution of a three-dimensional disturbed stress under mining disturbance. In the present invention, stresses are measured from three perpendicular directions which are inclined, so the difficulty in measuring a three-dimensional stress in a borehole is overcome; and a spatial stress value is measured by three three-direction sensing units, and thus the size and direction of a disturbed principal stress in the borehole are calculated.

A first graphical widget is generated based on the correlated first and second data streams. Finally, the first graphical widget is displayed on a graphical user interface (GUI).

A perforating tool and method of use in a wellbore. The perforating tool is placed at the end of a coiled tubing or other conveyance string. The perforating tool comprises a tubular housing providing an elongated bore through which fluid flows. The tubular housing has jetting ports used for hydraulic perforating. The tool is configured to operate in a flow-through mode when working fluid is pumped into the tubular housing at a first flow rate, with all of the fluid flowing through the end of the tool. The perforating tool is further configured to operate in a perforating mode when the working fluid is pumped into the bore of the tubular housing at a second flow rate. In this mode, all of the working fluid flows through the jetting ports. In an embodiment, the perforating tool includes a sequencing mechanism responsive to a sequence of flow rates to cycle the tool through operating modes.

Provided herein are portable apparatus as well as methods of analyzing a fluid using these portable apparatus. In some embodiments, the injection fluid can contain a polymer, but a polymer is not necessary. For example, the portable apparatus and methods may be used to determine viscosity, long term injectivity, filter ratio, or any combination thereof of the injection fluid. Advantageously, the surrogate core is temperature controlled.

A system for monitoring data quality in a drilling operation includes a controller and a plurality of data sources configured to provide data to the controller. The controller is configured to receive data from a plurality of data sources during a drilling operation; apply data quality rules to the received data; calculate a score for each data source of the plurality of data sources based on adherence of the received data for that data source to the data quality rules; compare the calculated scores for the plurality of data sources to determine which calculated scores meet or exceed a threshold score; receive a selection of one of the plurality of data sources having a calculated score that meets or exceeds the threshold score; and use the data from the selected data source. Methods and non-transitory machine-readable media for monitoring data quality are also provided.

A nuclear magnetic resonance (NMR) logging tool configured to be positioned in a borehole created in a subsurface formation. The NMR logging tool includes a magnet to induce a magnetic field in the subsurface formation, a transmission line, and a first shield positioned between the magnet and the transmission line.
