'Full Waveform Modelling', Presented by Professor Roy White on the Ikon Science booth at the EAGE Annual Exhibition 2006
FULL WAVEFORM MODELLING Illustration of some features of Ikon's full waveform modelling program Roy White, 15 June 2005 Main features · Frequency-slowness method (Fryer 1980, Kennett 2001) · Automatic settings for computational parameters (slowness increment and range, frequency increment) · The input is a spherical P-wave giving the required RMS velocity at the top of the log: no need to build a model to the surface · Automatic NMO correction and geometrical spreading correction (Ursin 19...

'Well Ties: The Essentials', Presented by Professor Roy White on the Ikon Science booth at the EAGE Annual Exhibition 2006
WELL TIES: THE ESSENTIALS why make a well tie well tie accuracy what matters how to do it Roy White Vienna, June 2006 Reference: White, R. and Simm, R., 2003. Good practice in well ties, First Break 21(10), 75-83. WHY DO YOU NEED A WELL TIE? Well to seismic correlation (zero phase data) : Is there a time shift? Is it zero phase? (or what is its phase?) How big are its side lobes? Inversion to impedance: Does the data really image layer properties? (does a step in impedance look like a step?) ...

'RokStar - digitisation of geological data; a case study in association with the University of Barcelona and Shell Exploration', Presented by Rudi Lubbe on the Ikon Science booth at the EAGE Annual Exhibition 2006
What most geologists are looking for is a tool that can reproduce the look and feel of their field logs, whilst at the same time retaining a geological database behind them... This new approach provides a flexible drawing tool allowing the user to produce `natural' looking logs, but also to use the images on screen to extract and store geologically sensible information. Geological information from many locations can be stored in one place and used to construct reservoir and outcrop models in 1D,...
