EAGE Workshop on Quantifying Uncertainty in Depth Imaging 2021
Listen to Neptune Energy and Geovariances joint presentation about uncertainty quantification in time-depth conversion, with Geovariances expert geostatistician Jean-Marc Chautru as the main speaker.
Oral presentation: Analyzing and quantifying Uncertainty in Time-Depth conversion
April 13, 2021 at 10:35 am MYT
Static geological models are made of horizons and faults which define their geometry. Both faults and horizons (in depth) are uncertain objects, which result from a time-to-depth conversion procedure involving variables such as time maps, velocity maps, markers at wells that in turn might all be affected by a given level of uncertainty. Even faults location may be uncertain and impact Gross Rock Volumes (GRV) calculated in the geological model (Correia et al., 2019). This paper details Methods to calculate depth maps, to identify and characterize potential traps and the associated uncertainty. […]
