acoustic sensing

A novel approach uses the heart-shaped signal in low-frequency distributed acoustic sensing measurements to estimate the hydraulic fracture tip distance before the hydraulic fracture intersects the monitor well, offering critical insight into the characterization of hydraulic fracture propagation.

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 describes a technique combining borehole acoustic reflection imaging with production logging in a horizontal well experiencing high water cut with the aim of enabling a mitigation plan.

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.

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

Diagnostics firm TGT launched its newest acoustic platform that it says broadens flow analysis by adding radial distance to the data collected.
