Systems and methods for remotely closing a switch that is downhole in a wellbore are disclosed. The switch has a body with a first connector and a movable piston assembly with a second connector configured to mate with the first connector. The piston assembly has a first position wherein the first and second connectors are separated and a second position wherein the first and second connectors are mated. A spring is disposed between the body and the piston assembly and configured to urge the piston assembly toward the first position. When the fluid in the wellbore reaches a pressure above a threshold, the piston assembly will move to the second position thereby closing the switch.

A stabilizer for use in a wellbore may include a downhole tubular configured to couple to a downhole conveyance in a wellbore, as well as two or more helical blades extending radially outward from the downhole tubular. The two or more helical blades are oriented about the downhole tubular to form respective flow paths between adjacent blades. Further, each blade of the two or more helical blades may include a line-of-sight face and a gauge ramp. The line-of-sight face is formed adjacent a leading inner blade wall of the blade at a lower end of the blade and is angularly offset from the leading inner blade wall. The gauge ramp extends from an outer surface of the downhole tubular toward an outer blade surface of the blade proximate the lower end of the blade.

A transducer, method, and downhole tool for acoustic logging. The acoustic transducer comprises a piezoelectric material comprising a body and grooves formed on the body. The grooves comprise a first groove that intersects with a second groove on the body. The method of acoustic logging a wall comprises transmitting an acoustic pulse at the wall using the acoustic transducer. The method also comprises generating a signal indicative of a reflection of the pulse using the acoustic transducer; and determining an acoustic parameter based on the signal using a processor. The acoustic logging tool is locatable in a wellbore intersecting a subterranean earth formation. The acoustic logging tool comprises the acoustic transducer and a processor configured to determine an acoustic parameter based on a signal generated by the acoustic transducer, the signal being indicative of the acoustic wave.

A method that includes deploying an acoustic caliper tool in a borehole, the tool having several axially-spaced acoustic transceivers; obtaining acoustic signal reflection measurements for the transceivers; estimating a distance-to-boundary value for the transceivers based on reflection measurements; calculating a tool inclination angle based on the distance-to-boundary values; and deriving a correction value based on the angle. A system that includes an acoustic caliper tool having several axially-spaced acoustic transceivers to obtain reflection measurements; at least one processor; and at least one memory in communication with the processor, the memory storing instructions that cause the processor to: receive the acoustic signal reflection measurements; estimate a distance-to-boundary value for the transceivers based on the reflection measurements; calculate a tool inclination angle based on the distance-to-boundary values; and derive a correction value based on the angle.

A system and method for an enhanced interconnect for downhole tools along a drill string used in subterranean operations is described herein. The system () may include a first drill string segment () comprising a first conductive element () and a second drill string segment () coupled to the first drill string segment. The system may also include a tool connect assembly () disposed within an internal bore of the second drill string segment. The tool connect assembly may comprise a second conductive element () electrically connected to the downhole tool, and the second conductive element may be electrically coupled to the first conductive element through at most two electrical interfaces.
