Abstract: An acoustic coupling device includes a base tape member having a hole, and a sensor side and a skin side each having an adhesive material thereon. The device further includes a tray removably attached to cover the skin side of the base tape member. The tray includes an indentation, which defines a concave face facing the hole, and a flat portion surrounding the indentation. The device further includes an ultrasound transferring gel disposed in the indentation, and a removable protective liner configured to cover the sensor side of the base tape member.

Abstract: A technique includes providing a source in a first well and a seismic receiver in a second well to detect a seismic event that is caused by the source. The technique includes referencing clocks in the source and receiver to a common reference time frame and determining a time in the reference time frame at which the seismic source generates the seismic event.

Abstract: A nano-based device includes a support structure providing a support surface, a second structure providing a second surface angled with respect to the support surface, and at least one nano-emitter provided on the second surface.

Abstract: An explosive device includes a housing, and at least one of an initiator and an explosive in the housing. The at least one of the initiator and explosive are activatable in response to stimulus from a control line. A monitor in the housing monitors a state of the stimulus to enable determination of a status of the explosive device.

Abstract: An apparatus for use in a well comprises a structure having at least a first portion formed of a first material, and a detector to detect a signal associated with a component located either within or beyond the structure. The first material has a property that reduces attenuation of the signal.

Abstract: Methods for testing single-use electrical devices (e.g., explosive detonators and initiators) are provided to ensure operating reliability of such devices when used in the field. These methods facilitate testing of non-destructible components of single-use electrical devices at operating parameters during production or anytime before field use.

Abstract: A computer controllable testing and monitoring station forms short-term intervals of simulated alternating current power level disturbance, either undervoltage (sag) or overvoltage (swell). The station forms the short term voltage sags or swells so that their effects on sensitive equipment can be measured. The starting point of the sag or swell disturbance, as well as the time duration of the disturbance, can be accurately controlled.
