Abstract: According to an embodiment, a method for analyzing microseismic events associated with hydraulic fracturing detects a new microseismic event and assigns it to a cluster of other events having similar characteristics. Cluster characteristic(s), e.g., average event(s), average source mechanisms, and/or average locations, are updated and used to characterize a future microseismic events.

Abstract: Methods and systems for deriving S-wave velocity information from the low- frequency content of ambient noise are described. The ambient noise can be collected on a dedicated record or on a production record associated with the receivers of a three-dimensional seismic survey. The methods and systems use one of a plurality of analysis models selected based on quality factors of the ambient noise data. The methods and systems analyze the data at a plurality of single frequencies then transform the velocity versus frequency data into velocity versus depth data.

Abstract: Apparatus, computer instructions and method for controlling an energy output of a source array (300) to be used in a seismic survey for illuminating a subsurface. The method includes generating (600) a model ( β ) based on up-going (U) and down- going (D) components of seismic waves generated by source elements (300-i) that form the source array (300); calculating (602) the amplitudes and phases of each source element (300-i) based on the model ( β ); and driving (604) the source array (300) based on the calculated amplitudes and phases for the source elements (300- i) so that a ghost generated by the source array (300) is reduced at emission.

Abstract: Methods for seismic exploration of a subsurface formation increase productivity by simultaneously actuating closely located vibratory sources. Individual vibrations generated by different sources actuated simultaneously are encoded to enable separation of seismic data corresponding to each of the individual vibrations.

Abstract: Systems and methods are disclosed for attenuating noise during seismic acquisition. The method includes compiling a seismic data set from data received by a plurality of receivers. The seismic data set includes noise energy from a noise source. The method further includes calculating a plurality of cross-correlation panels based on a reference trace from a reference receiver. The reference receiver is one of the plurality of receivers. The method includes estimating the location of the noise source and applying a correction to the plurality of cross-correlation panels based on the estimated location of the noise source generating a plurality of corrected panels. The method also includes analyzing the plurality of corrected panels for a noise operator to attenuate noise in the seismic data set.
