The Source Scanning Algorithm was published by Kao and Shan (PDF) in 2004, describing a method that is akin to Kirchhoff imaging. It appears that many microseismic event detection methods such as SET, PSET, CMM, and Voxel Focusing are similar or equivalent to the Source Scanning Algorithm. At NanoSeis we have had good success using the Source Scanning Algorithm.

Meighan et al. (PDF) discuss microseismic surface monitoring results in the Permian Basin.

Drew and White (PDF) presented an eye-opening paper at the 2008 SEG convention analyzing the uncertainty in the use of hodograms to determine the azimuth from borehole receiver arrays to reported events. Note the scatter in the azimuths for rigidly paired receivers that is shown in Figure 6.

Hayles et al (PDF) presented another eye-opening paper at the 2011 SEG convention, showing a comparison of processing results of a borehole dataset by four different vendors (only three vendor results are shown in the abstract, but four were included in the presentation). They conclude that "microseismic processing remains in its infancy".

Diller and Gardner (PDF) published an abstract for the 2011 SEG convention that compares results from simultaneous monitoring of microseismic borehole and surface data.
