VelocityVolume is an integral component of VelocityManager developed to manage a range of complex depth conversion models. Designed to resolve a number of complex situations which arise in depth conversion, which can take a substantial amount of an analyst’s time to resolve…… “Bringing the power of advanced depth conversion technology to the user of industry standard mapping systems”. Featuring:- Depth conversion of secondary time grids - Designed to depth convert ‘any’ secondary time grid from the project, which is not part of the original set of ‘primary’ time horizons, whilst using the derived velocity field. For example:- fault plane surfaces which may cross cut several primary horizons, isolated ‘reflections’ from sand bodies such as Palaeocene sands, and also Plattendolomite reflection within the Zechstein interval. Depth to time conversion - Often essential in order that the interpreter can obtain a time ‘pick’ equivalent to a depth point in a deviated well, where no check shot data is available. In this manner the geophysicist can interpret a seismic reflection which will correspond in time to the deviated well depth value. This is often a critical problem in field development situations. Well forecast - Will evaluate any number of grids at a specified x, y, location for drilling. The evaluation is very accurate in difficult situations which may prove inaccurately managed in mapping packages i.e. either close to faults, or close to null values. Velocity time slice - Will deliver an average velocity map at a constant time value, using the derived velocity field. Often very useful in evaluating the absolute ‘pull-up’ effect of a velocity field, unaffected by structure – An advanced QC tool. Depth convert constant time slice - Makes a constant time grid, and depth converts it using the derived velocity field. A second approach to demonstrating the distortion of the velocity field on a ‘flat’ time horizon – An advanced QC tool. Computes all interval velocities - Uses the velocity model derived from functions, this function will deliver all the ‘equivalent’ interval velocity grids. An ideal tool for evaluating the effect of specific velocity functions. |
