"Widely regarded as the total solution to 3D velocity modelling and depth conversion". The main features of VelocityManager are:
Other feature include:
VelocityVolume™ 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, isolated ‘reflections’ from sand bodies such as Palaeocene sands and also Plattendolomite reflection within the Zechstein interval. Depth convert fault planes - Fault plane surfaces may cross cut several primary horizons, and velocity boundaries, within each the velocity may increase with depth. The fault plane can be depth converted using the velocity model developed within the velocity volume to depth convert the fault plane time grid to give precise depth ties to our horizons in depth and x,y. 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 (Grid back interpolation) - Will evaluate multiple grids at a specified x, y, location for drilling. The evaluation is very accurate in difficult situations, poorly managed by more conventional processes in common use. i.e. either close to faults, or close to null values. Based on a second generation Geostatistical process, it is both very reliable and accurate under virtually any situations. 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 quality control 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 quality control 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. Fault plane depth conversion Fault planes which cross-cut some or all horizons and complex velocity layers, can be depth converted interactively, and very accurately in VelocityManager, whilst still utilising a layer cake velocity model. VelocityManager will intelligently apply the appropriate velocities to the fault plane grid, node by none, utilising exactly the velocity model used to depth convert the time horizons, This will result in fault planes, in depth, which both intercept the horizons at exactly the same depths. Depth converting fault planes is very fast, very accurate, and very user friendly in VelocityManager. Seamless linking Velocity model, depth convert and depth migrate, your time grids, with VelocityManager by seamlessly linking to your Z-Map, CPS-3, EarthVision, Petrel or Kingdom grid files.
