Title: Stochastic detection of transgressive and regressive sequences from well-log data using discrete wavelet transform: first results


Prof. Guillaume Caumon (Univ. Lorraine)

Research Topics:

Stratigraphic Sequences Stochastic Simulation for Well stratigraphic interpretation S4Wells

Maximum Flooding Surfaces (MFS) correspond to the most marine depositional conditions and may be interpreted from the gamma ray (GR). Assuming that the GR is a proxy of the relative sea level, high values of GR correspond to deepest depositional conditions, and low values of GR correspond to shallowest depositional conditions.

A multi-scale GR analysis leads to the computation of a probability of finding a MFS at each depth of GR acquirement using:

The Discrete Wavelet Transform (DWT) Stochastic detection of transgressive and regressive sequences from well-log data using discrete wavelet transform: first results.

The Continuous Wavelet Transform (CWT) Stochastic simulation of stratigraphic sequences from well log data using continuous wavelet transforms.

Once the probability is computed, MFS may be stochastically simulated to assess uncertainties of stratigraphic sequence interface position along wells.

Computer-assisted Chronostratigraphic Multi-Well Correlation  WeCo

Well correlation based on facies interpretations and paleo-distality. Markers are associated if they are consistent with depositional environments. Along the structural strike direction, chronostratigraphy tends to associate similar facies. At the opposite, along the structural dip direction, proximal shallow facies are associated with distal deep facies, other associations are excluded.

Well correlation based on facies interpretations and dipmeter data. Chronostratigraphic surfaces are simulated between well markers using Bézier cubic interpolations. All possible interpolations are compared with a theoretical depositional profile and the smaller the variation, the higher the likelihood.

Dipmeter Data Stochastic Simulation from 4-Directional Resistivity Log

Using the Dynamic Time Warping (DTW) to correlate four-directional resistivity logs, it is possible to associate resistivity markers minimizing the variance. Once markers associated, it is possible to compute dips and dip directions for each marker associations.

Achievements (2019 - 2020):

  • Computer-assisted multi-well stochastic correlations: Chronostratigraphic surface simulation using Bézier cubic interpolations
  • Magnetostratigraphic time-to-depth multi-well correlation using the Dynamic Time Warping on well-log data.
  • Facies correlation based on lithostratigraphic, and chronostratigraphic associations based on the paleo-environment (transport direction, paleo-depth, paleo-distality ...) using Dynamic Time Warping on well-log data.

Achievements (2018 - 2019):

  • Stochastic detection of stratigraphic sequences from well data (Gamma Ray log) using discrete wavelet transform (Haar functions).
  • Sedimentological interpretation of well core samples and creation of different well logs based on these different interpretations (Petrophysical facies, genetic facies …) + parasequence interpretations.
  • Facies transition probability computation to constraint stochastic correlations using observed data.
  • Stochastic multi-well correlation from well data (Gamma Ray log + genetic facies interpretation on core samples) using Dynamic Time Warping algorithm to compute the n-best correlations.
