Achieving Business Value Using Borehole Sonic Data

presented by 

Brian Hornby

Borehole sonic is the one logging survey that directly connects and is used by both Geophysicists interested in exploring with surface seismic data and Petrophysicists interested to quantify formation properties and structure penetrated by the borehole. Since the first basic sonic tools were developed in the 1950s, the technology has come a long way, with multiple sources firing a range of acoustic modes coupled with large receiver arrays detecting motion from all directions. So you may ask “What does this fancy new technology buy me in terms of business value?” This is the key question and we have to be informed users, first in order to understand and effectively get value from the “bread and butter” compressional and shear slowness logs, and next in order to derive additional value beyond those basic sonic slowness logs. Now for advanced applications a pretty picture showing an interesting physical phenomena is not success – success is showing how the results behind the picture guided how you fracked or completed your well, for example.

Speaker Biography:
Brian Hornby is Chief Scientific Advisor for Acoustics at Halliburton where he leads efforts focused on borehole sonic answer products. Brian received his Ph.D. degree from the University of Cambridge in 1995 and has over 30 years’ experience in the industry, beginning with field engineer and then moving to Research and Development roles.  He is a SPWLA Distinguished Lecturer and has received numerous awards including Petrophysics “Best Paper” in 2000, 2007 Geophysical Prospecting best paper, and the 2007 EAGE Cagniard Award. Brian has 15 patents, authored 40 papers in refereed professional journals, and has made more than 100 professional society presentations.
