Relating Depositional Environments to Logs

Purpose

This approach is oriented to combining geology, core analysis and petrophysics into a single and coherent reservoir model.

Goals

Requirements

Examples

Hartzog Draw, Wyoming Clastic Depositional Environment

For three cored wells, identified six different depositional facies as described from the cored interval:

Location

Geologic Model

Training

Trained the neural network using the Bud Christensen #2 and the Federal AS #1 to recognize the six different facies using:

Cross Section of Results

Billings Nose North Dakota Carbonate Depositional Environment

For the cored well (Stuart 1-19) identified six different depositional facies as described from the cored interval:

Location

Geologic Model

Training

Trained the neural network to recognize these six different facies using:

Did not use resistivity, since fluid content is not of interest for this approach. The neural network resulted in a 96.5% comparison of the training region with the core descriptions.
