    Abstract: Various embodiments include methods and apparatus structured to install an optical fiber cable into a well at a well site. In a from-bottom-to-top embodiment, an anchor deployed at a selected location in a hole of the well can be used and the optical fiber cable can be pulled up to a surface of the well from the selected location. In a from-top-to-bottom embodiment, an optical fiber cable can be moved down from the surface until an end of the optical fiber cable is locked at a selected location by a catcher disposed at the selected location. With the optical fiber cable in the well, a portion of the optical fiber cable can be coupled to surface instrumentation. Additional apparatus, systems, and methods can be implemented in a variety of applications.

    Abstract: Disclosed is a system and method for improving the performance of downhole Distributed Acoustic Sensing (DAS) systems by simultaneous use of co-propagating and counter-propagating Distributed Raman Amplification (DRA). It uses a surface DRA system with a surface DAS system to combine their laser sources where the distal end of the downhole sensing fiber use uses a Wavelength Division Multiplexer (WDM) to optically split the DRA and DAS signals onto two optical fibers. The DAS fiber/signal is terminated with a low reflectance termination to minimize a potential back reflection whereas the DRA fiber is terminated with a high reflectance termination causing all the light to reflect back up the sensing fiber. This arrangement allows for simultaneous co and counter-propagating DRA of the DAS signals, both the transmitted pulse and the back scattered light, thus creating the maximum amount of gain possible.

    Abstract: Multi-well fracture control incorporates physical well properties into a model for fracture geometry to determine optimal mitigation techniques for well interference effects. Sensors in a monitoring well and a treatment well measure well properties during fluid injection and pumping in the treatment well. The measurement data is used to constrain fracture geometry model. The fracture geometry model is then used to calculate fracture growth rates and direction which are used to calculate an estimated time for the occurrence of well interference effects in the multi-well system. From the fracture geometry model, fracture growth rates and direction, and the estimated time for the occurrence of well interference, locations of potential well interference effects are predicted. A mitigation strategy is planned based on the predicted location and time of well interference events. Treatment actions can be taken in anticipation of the well interference events.

    Abstract: A new approach to pipeline pigging using electro acoustic technology (EAT) is described in which the data from a pigging operation can be transmitted in real time to optical fiber on the outside of the pipeline and detected using distributed acoustic sensing (DAS) techniques, including the precise location, velocity and acceleration of the pig using the DAS technique. Thus the sensor data can easily be mapped to its precise location in real time. The EAT sensors use the DAS fiber as a data transmission line by converting electrical or optical signals to acoustic signals which excite the fiber and can be detected by an interrogator at the pig launch site.
