A pressure sensor including a transducer housing, a transducer crystal disposed in the housing in vacuum conditions, a driver in contact with the crystal transducer, and a deflectable member in contact with the driver on one surface and exposed to ambient pressure on the opposite surface thereof. A borehole system including a borehole in a subsurface formation, a string in the borehole, and a sensor connected to the string.

Pressure sensor and borehole system

A convertible sensor module kit including a housing, a sensor port in the housing and having a seal block receptacle fluidly coupled to the sensor port, and a tubing pressure seal block or an annulus pressure seal block disposed in the receptacle. A module for sensing annulus pressure comprising a housing, a sensor port in the housing and having a seal block receptacle fluidly coupled to the sensor port, and an annulus pressure seal block disposed in the receptacle, the block including a communication channel intersecting a monitor channel, the monitor channel in fluid pressure connection with the sensor port.

Convertible gauge module and system

A method for transmitting an optical signal and an electrical signal and/or power in a borehole penetrating the earth includes transmitting the optical signal using a hybrid fiber optic cable disposed in the borehole, the hybrid fiber optic cable includes an optical fiber for transmitting the optical signal. The method also includes transmitting the electrical signal and/or power using the hybrid fiber optic cable, the hybrid fiber optic cable further includes (i) a first electrically conductive sheath circumferentially surrounding the optical fiber and having a first electrical connector and (ii) a second electrically conductive sheath circumferentially surrounding the first electrically conductive sheath and having a second electrical connector for transmitting the electrical signal and/or power.

Method and apparatus for transmitting electric signals or power using a fiber optic cable

A system for communicating a signal between a tool and a signal processing unit includes a signal processing unit configured to at least one of transmit and receive the signal and a first cable coupled to the signal processing unit. The system further includes a tool having a second cable extending from the tool and configured to at least one of receive the signal transmitted by the signal processing unit and transmit the signal received by the signal processing unit, wherein signal is communicated between the first cable and the second cable by crosstalk.

Use of crosstalk between adjacent cables for wireless communication

The present disclosure relates to apparatuses and methods for terminating communication on a communication line between a carrier and at least one node located at a subsurface location. The apparatus may include a control member configured to initiate termination of communication in response to a controlled signal. The apparatus may also include a communication linkage configured to terminate the communication in a manner that cannot be remotely restored in response to the control member. The apparatus may also include a power source to maintain power to the communication linkage termination operation. The apparatus may be configured to use energy from the communication line to cause the communication linkage to terminate communication. The apparatus may be configured to use a communication linkage that is at least partially consumable. The method includes the use of the apparatus.
