For the Panoma project the geomodel workflow included the following steps:
- Identification of lithofacies and associated petrophysical properties
in a subset of cores
- 1900’ of core was described at half-foot intervals using a digital description scheme that allowed efficient lumping and splitting options
- Cores were from 8 wells (triangles) selected to give optimal geographic and stratigraphic coverage
- Lithofacies were then predicted in 500 non-cored wells using a neural network trained on the core lithofacies
- Next was the building a 3D cellular model by extrapolating lithofacies into areas between the lithofacies wells using commercial stochastic modeling software
The focus of this paper is on the identification of lithofacies in core and
prediction of these lithofacies in non-cored wells
