Borehole Monitoring

Comprehensive, real-time fracture characterization

Magnitude borehole monitoring services accurately map the azimuth, height, and length of an induced fracture in real time to enable stimulation experts to understand the nature of the fracture.Our borehole monitoring services use downhole multi-component seismic sensors to record microseisms generated during the fracturing process. The obtained data is then processed to determine the location and seismic attributes of the events. By locating these events, a detailed map of the height, length, width, and azimuth of the disturbed earth can be constructed.

Magnitude can deploy multiple arrays, using either the vertical or horizontal portions of nearby observation wells to ensure that the full extent of the treatment well is monitored. When multiple observation wells are used simultaneously, the results will include moment tensor evaluation.

Magnitude’s proprietary three-component migration technique is utilized, resulting in a significantly improved signal-to-noise ratio. This, in turn, detects smaller events or events that are farther away, and reduces sensitivity to environmental noises.

The velocity model is refined to reduce the statistical uncertainty, using a nonlinear, simulated annealing velocity inversion process, which ensures the use of the best possible velocity model during microseismic processing, providing increased confidence in event locations.
