IHS Kingdom Webinar – Quantifying Depth Conversion and Volumetric Uncertainty

We will be presenting two webinar sessions on Thursday 23rd March 2017 at 9am GMT and 3pm GMT covering an overview of some of the exciting features available in the 2017 release of VelPAK, our depth conversion package.

Requirements for depth conversion differ in emphasis between disciplines.  For example, a driller needs a precise depth of horizons at a particular location, whereas the economist would like to know the probable range of Gross Rock Volume for a particular trap, while a petrophysicist would like to use the velocity information for quantitative seismic interpretation.

Typically, depth conversion just focuses on the first case, but the Kingdom VelPAK module provides answers to all the questions asked of the depth conversion, providing accurate depth models along with quantified uncertainty for risk reduction in reserves estimation, and enhanced velocity volumes for Quantitative Seismic Interpretation & reservoir characterisation.

VelPAK is a fully featured package for seismic time to depth conversion, containing what we believe is the most complete feature set of any package on the market.

This overview of the VelPAK product will touch on many of these features, starting with building a velocity model from well and seismic data that can accurately predict depths away from wells, then assessing the uncertainty in the target structure through stochastic simulation, and finally enhancing the velocity model for uses beyond depth conversion.

It’s essential to get an estimate of the variance in our depth conversion.  VelPAK can produce a range of equi-probable depth conversions. The model parameters can be stochastically varied to measure the uncertainty in the depth conversion, resulting in a probability distribution function for our target volumetrics.  We do this by perturbing the mapping functions, choosing equally likely solutions from parametric functions, or randomising regressions within known confidence bands.

Volumetrics and animations can be recorded to provide significantly greater insight into the prospect than just a simple depth conversion alone, and lever analysis tools allow us to determine which factors in the depth conversion correspond to the biggest variations in GRV.
