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.

Systems and techniques for non-contact measurement of coiled tubing motion are disclosed. In one embodiment, a system includes a laser source and a laser motion sensor. The laser source is configured to provide laser light that illuminates the coiled tubing as the tubing moves. The laser motion sensor is configured to collect and process laser speckle images and compute measurements of coiled tubing movement based on the laser speckle images.

Methods and apparatus for determination of parameters related to the movement of a coiled tubing string

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.
