Chan Plot Package

Calculate the data needed to construct and analyze Chan plots

Usage

Run the workflows from this package to perform the calculations. The schedules may be adapted to use different contexts.

The script Chan Plot Visualization can be used to extract the data needed to create Chan plots in a dashboard.

Details

The water oil ratio (WOR) and its first derivative (WOR') are analyzed and categorized into categories according to the following logic:

  • constant water oil ratio:  delta WOR < 1 and delta WOR' between 1 and 2
  • normal displacement:  delta WOR is approx. 1 and delta WOR' is between 1 and 3
  • multilayer channeling:  delta WOR > 1 and delta WOR' ≥ 3
  • rapid channeling:  delta WOR ≥ 2 and delta WOR' > 2

Data Requirements

The following data is required on well level:
