... seismic data. We show from this modeling that maximum 4D amplitudes of 6-10% NRMS are strongly impacted by gas thickness, while 4D time-shifts have more complex behavior and cannot be integrated in a simple way into a predictive model. Due to relatively high noise levels in comparison to the expected 4D...

... ABSTRACT Microseismic monitoring aims at detecting as weak events as possible by maximizing the signal-to-noise ratio (SNR) of the detection parameters. Whilst the signal depends on a priori unknown source radiation and propagation effects, the noise levels on the receivers can be measured...

A comparison of noise statistics for different data vintages shows higher noise levels during the most recent survey. In spite of this, robust amplitude difference images for the reservoir interval continue...

... technique is capable of estimating and removing both spatially incoherent noise and inconsistent noise across multiple components. We show two real-world examples fromWestern Australia that were collected using the AIRGrav instrument. The estimated noise levels are consistent with previous data analysis...

Results prove the capability of the proposed scheme to perform automatic and accurate microseismic event detection in challenging noise...

... with a zero-mean normal distribution does not. So the relative magnitude of such noise can be characterized by the deviation of the first-digit fre- quency from Benford s law. A high noise level can result in a large Benford deviation. This approach is first demonstrated by a simple mathematical example using...
