fiber optics

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.

The authors of this paper describe systems that combine fiber-optic communications for subsea control systems and downhole fiber-optic sensing systems into the same subsea optical distribution system.

This paper describes efforts at the Hydraulic Fracturing Test Site 2 to collect a research data set to improve understating of spatial and temporal hydraulic fracture dimensions, proppant distribution, and reservoir depletion.

From refracturing old wells to ones that don’t have to be fractured at all, notable producers argue that experiments are paying off.

The authors of this paper describe the development and implementation of a data-streaming solution that allows for real-time processing and interpretation of fiber-optics data.
