WebDepth conversion (domain conversion) of seismic time interpretations and related data within Petrel is a critical skill set for interpreters. However, there is no single methodology that is optimal for all cases since the available seismic and geologic control varies in quantity and quality within each project. WebTime-to-depth conversion means that each seismic data point in the time domain will be given a depth coordinate. Each point keeps its XY location. There is no lateral displacement, only a vertical one. Such approach is insufficient in complex domains such as structural plays or salt plays. WebJul 6, 2024 · Seismic data is recorded in the time domain, namely the time taken for a sound wave to travel from the seismic source to the target reflector and back to the receiver.
