Abstract: This invention relates to devices and processes for geophysical prospecting, subsurface fluid monitoring and, more particular, to the use of interferometric techniques using Control Source Electromagnetic (“CSEM”) and Magnetoturelic (“MT”) signals to create images of sub-surface structures and fluids.

Abstract: A method for producing oil or gas from multiple wells, the wells including at least a first well and a second well, with each well using an artificial lift system that includes a plunger associated with a motor valve off time, and first and second identical connecting subsystems that connect their respective wells to a common sales line. The first connecting subsystem includes: a) a plunger arrival sensor connected to a micro controller; b) a wellhead connected to the first well; c) a motor valve connected to the wellhead; d) first and second pressure transducers on either side of the motor valve, conductively coupled to the micro controller; and e) a micro controller for keeping the motor valve closed during the motor valve off time, and extending the motor valve off time following a determination of the existence of a pressure spike in the common sales line.

Abstract: A device and method for monitoring the condition of a thermocouple. In a preferred embodiment the device comprises a pair of thermocouples, each thermocouple comprising first and second thermoelement wires, and a diagnostic element selectively electrically coupled at a junction with one of the thermoelements. In a preferred embodiment, the diagnostic element is selected such that it is more stable at the expected operating temperature range of the thermocouple than the thermoelement wires themselves are. The diagnostic element can be switched into electrical connection with any of the thermoelements forming the thermocouples to thereby define one or more loops. An initial loop resistance is measured and recorded around each of the thermoelement/diagnostic element loops. This initial resistance is stored in a calibration matrix as a reference value. The initial loop resistance may be taken as part of a calibration process or during initial operation of the thermocouple.
