6.00 Technical Presentation: Alan Meulenbroek –
A Converted-Wave Refraction Statics Technique with Applications to Near-Surface Characterization.

About the Presentation:

Converted-wave static correction requires a specialized processing approach due to the differences in compressional (P) and shear (S) wave properties. This thesis examines a method based on picking converted refractions on a 3C shot record. When combined with the P-wave refraction picks, a near surface model is produced, from which statics are derived. For simplicity and minimized computational expense, a single composite refraction spread is built extending over the entire line. Synthetic modelling indicates how the ratio of S to P time-depths can be tuned to give the true VP/VS ratio in the near surface. The derived statics are compared to a converted-wave residual statics method used in industry, with good results. A comparable CCP stack is also produced.

About the Speaker:

Alan Meulenbroek was born and raised in Brisbane, graduating from Wavell State High School in 2002. Alan enrolled in BScApp(Geophysics) degree at UQ in 2003 because he had no clue what to do out of high school, and the degree had all the courses laid out. Having no idea what exploration geophysics was all about until the start of 3rd year, it was lucky for Alan that he enjoyed the course material and stuck with it. Alan is the Queensland recipient of 2006 Australian Society of Exploration Geophysicists’ scholarship to attend AESC in Melbourne (2-6 July). Alan has a love of cycling and last year cycled his bike around Kakadu National Park (in the dry season!). He would have gone from Darwin to Broome this year but had no time with the workload of 4th year honours. Alan has worked on 3D seismic crews in Bowen Basin last Summer as a juggy, and for the last year has been picking first breaks part time to fund uni.
