Abstract: An intelligent water-monitoring system includes a water-monitoring device installable inline with a building water system (e.g., at an inlet of the system). A plurality of sensors of the water-monitoring device are configured to sense properties of the building water system, such as water pressure and water flow. The water-monitoring device has a valve and a controller configured to automatically shut the valve in response to sensed data indicating a possible problem in the building water system. The intelligent water-monitoring system may include an app executable by a computing device to display information based on the sensed data.

Abstract: A method of performing a fracture operation is provided at a wellsite. The wellsite is positioned about a subterranean formation having a wellbore therethrough and a complex fracture network therein. The complex fracture network includes natural fractures, and the wellsite stimulated by injection of an injection fluid with proppant into the complex fracture network. The method involves generating wellsite data comprising measurements of microseismic events of the subterranean formation, modeling a hydraulic fracture network and a discrete fracture network of the complex fracture network based on the wellsite data, and performing a seismic moment operation. The method involves determining an actual seismic moment density based on the wellsite data and a predicted seismic moment density based on shear and tensile components of the simulated hydraulic fracture network, and calibrating the discrete fracture network based on a comparison of the predicted moment density and the actual moment density.

Abstract: A technique includes receiving, during a hydraulic fracturing operation in a subterranean structure, pressure data and fluid injection rate data. One or more properties of the subterranean structure are determined in real-time using the received pressure data and fluid injection rate data.

Abstract: Methods and apparatus for creating a velocity profile of a formation surrounding a borehole by checkshot measurements while moving the tool along the borehole. A conveyance and a sensor section are configured to move the sensor section in the borehole. At least one receiver is configured to detect signals generated at or near the surface while the sensor section is moving in the borehole.

Abstract: A borehole seismic acquisition tool configured for release from a stuck position within a borehole having a tool body with at least one sensor package, an anchoring arm, and anchoring arm linkage adapted to connect the anchoring arm to the tool body. The anchoring arm linkage includes a weakpoint mechanism adapted to break in response to a minimum threshold amount of breaking force being applied upon the weakpoint mechanism. The anchoring arm includes a first end adapted for contacting a borehole wall surface and a second end pivotally attached to the anchoring arm linkage. The anchoring arm also includes a movable cam removably secured to the first end via a first connector pin. The cam being at least partially rotatable about the first connector pin and configured and arranged to rotate against the borehole wall by a pulling force at a top portion of the borehole seismic acquisition tool.

Abstract: A technique that is usable with a well includes deploying an assembly into a wellbore. The assembly includes at least one sensor. A fracturing fluid is injected under pressure into the wellbore to hydraulically fracture a subterranean formation of interest. The technique includes isolating the sensor from the fracturing and measuring acoustical energy that is generated by the hydraulic fracturing using the sensor(s).

Abstract: A technique is described for releasing a borehole seismic acquisition tool from a stuck position within a borehole. The borehole seismic acquisition tool includes a tool body having at least one sensor package. The borehole seismic acquisition tool further includes an anchoring arm, and anchoring arm linkage adapted to connect the anchoring arm to the tool body. The anchoring arm linkage includes a weakpoint mechanism adapted to break in response to a minimum threshold amount of breaking force being applied upon the weakpoint mechanism. The anchoring arm includes a first end and a second end. The second end of the anchoring arm is pivotally attached to the anchoring arm linkage. The first end of the anchoring arm includes a tip portion which defines a slot. The anchoring arm also includes a movable cam inserted into the slot and removably secured to the first end via a first connector pin inserted through an aperture in the cam.

Abstract: An electronic key telephone station set includes a plurality of nonlocking line selection buttons. Adjacent each button is a pair of light emitting diode lamps, one for indicating which line selection button has been actuated and one for indicating which ones of other lines having an appearance on the station set are in use. Digital data coupled to and from the station set control the activation of the indicating lamps as well as the type of alerting signal generated to indicate an incoming call. Numerous other features may be advantageously implemented under data stream control.
