Abstract
A computer-implemented method for detecting or monitoring subsurface events includes receiving a data signal obtained from a subsurface region, and performing a continuous wavelet transform whereby a continuous wavelet is superimposed on the received data signal to determine one or more wavelet transform coefficients. The method further includes determining a signal energy from the one or more wavelet transform coefficients at a plurality of distinct scales, and detecting an occurrence of a subsurface event based on the signal energy.
Claims20
A computer-implemented method for detecting or monitoring subsurface events, the method comprising:
- (a) receiving a data signal obtained from a subsurface region;
- (b) performing a continuous wavelet transform whereby a continuous wavelet is superimposed on the received data signal to determine one or more wavelet transform coefficients;
- (c) determine a signal energy from the one or more wavelet transform coefficients at a plurality of distinct scales;
- and
- (d) detecting an occurrence of a subsurface event based on the signal energy and the received data signal.
A system for detecting or monitoring subsurface events, the system comprising:
- a computer system comprising:
- one or more processors;
- and
- one or more memory devices coupled to the one or more processors storing program instructions including an event detection module that, when executed by the one or more processors, cause the one or more processors to:
- receive a data signal obtained from a subsurface region;
- perform a continuous wavelet transform whereby a continuous wavelet is superimposed on the received signal to determine one or more wavelet transform coefficients;
- determine a signal energy from the one or more wavelet transform coefficients at a plurality of distinct scales;
- and
- detect an occurrence of a subsurface event based on the signal energy and the received data signal.
