  "Sigma Explorations Inc. [via my favourite broker, Cathy Hufnagl] remains my go-to seismic broker since 2006 and I have no need to look any further.  Cathy's full-time team always provides exceptionally friendly, prompt and professional service - and that goes a long way with me.

  SigMap^TM is a wonderful tool for quickly jumping to a location, filtering down to the seismic of interest, and immediately requesting a QI.

  Additional features like the ability to download shape files of the seismic I have either requested for QI, or already QI'd, and the simplistic ability to import into SeisWare^TM for display and analysis against all the remaining information in the project is a large benefit to my workflow and makes presenting seismic acquisition proposals to management easy and straightforward."
