US Patent:

8064288, Nov 22, 2011

Filed:

Jun 16, 2009

Appl. No.:

12/485084

Inventors:

Chuntao Liang - Houston TX, US
Michael P. Thornton - Houston TX, US
Peter Morton - Katy TX, US

Assignee:

Microseismic, Inc. - Houston TX

International Classification:

G01V 1/36

US Classification:

367 45, 367 73, 702 17

Abstract:

A method for seismic event mapping includes adaptively velocity filtering seismic signals recorded at selected positions. The velocity filtered signals are transformed into a domain of possible spatial positions of a source of seismic events. An origin in spatial position and time of at least one seismic event is determined from space and time distribution of at least one attribute of the transformed seismic data.

International Classification:

G01V 1/40

US Classification:

367 25, 367 40

Abstract:

A method for synchronizing recordings of seismic sensor signals between at least two time indexed recording units includes cross-correlating signals recorded by each of a first and a second recording unit from a same reference sensor. The reference sensor is deployed proximate a subsurface volume to be evaluated and generates at least one of an optical and an electrical signal in response to seismic amplitude. Peaks in a power spectrum of the cross correlated signals are determined. The reference signals recorded by each of the first and second recording units are notch filtered using at least one notch frequency selected from the power spectrum. The notch filtered reference signals are cross correlated and a time offset between recordings made by the first recording unit and the second recording unit is determined from the cross-correlated, notch filtered signals.
