fiber optics

This paper explores the development of fiber-reinforced thermoplastic sucker rods as a promising alternative for overcoming the limitations of steel sucker rods and thermoset fiberglass sucker rods.

One hydraulic fracturing job can stimulate two wells, but economic success hinges on doing it in the right place for the right price.

The new frontier of production improvement combines surveillance techniques and analysis to determine which variables boost output.

This study highlights the strategic implementation of coiled tubing to convey perforating guns in extended-reach wells, overcoming the lockup effect through the deployment of downhole tractors and real-time monitoring tools.

This paper describes a case study in which, in the absence of a conventional production log, distributed fiber-optic sensing, in conjunction with shut-in temperature measurements, provided a viable method to derive inflow zonal distribution.

The authors integrated azimuths and intensities recorded by fiber optics and compared them with post-flowback production-allocation and interference testing to identify areas of conductive fractures and offset-well communication.

Distributed fiber-optic sensing data from distributed temperature sensing and distributed acoustic sensing can be used to monitor annuli liquid levels in production wells, further allowing calculation of leak rates and inference of leak path.

The authors of this paper describe a project in which Raleigh frequency-shift distributed strain sensing monitored during production in a far-field observation well was translated to an estimated pressure profile.

This paper presents a comprehensive technical review of applications of distributed acoustic sensing.

New studies are a reminder that the effort to identify, classify, and nullify frac hits remains paramount to the future of the unconventionals business.
