An upgrade of the SYNTH algorithm has been developed which includes severalnew features and bug fixes. These new features include the ability to import las (log ASCII standard) logs, a normal moveout and a normal moveout removed option to better simulate the effects of NMO removal. In addition to these options are more realistic attenuation effects including transmission losses, spherical divergence andsimple Q attenuation. Further developments to the user interface of SYNTH also make it easier to view the parameters used to generate the synthetic. SYNTH currently uses a robust MATLAB based platform capable of simulating many earth effects to create synthetic P-P or P-SV offset gathers. SYNTH also interacts with other MATLAB based programs for editing well logs (LOGEDIT), creating wavelets (WAVELETED) and creating well log cross sections (LOGSEC).
