TOC Analysis in 10 Minutes
TOC Analysis
There are lots of different methods out there for analyzing TOC. In Danomics Petrophysical Insights we offer 6 distinct methods. These include:
- Schmoker’s method: An empirical, density-based method.
- RhoB methods: An average of 12 of the most popular empirical density-only methods.
- Vernik’s method: A density-based method that utilizes clay density as an input
- Passey’s Sonic method: The classic Delta-logR model based on resistivity and sonic, which is visually calibrated.
- Passey’s Neutron method: The N-logR method based on resistivity and neutron, which is visually calibrated.
- Passey’s Density method: The D-logR method based on resistivity and density, which is visually calibrated.
- Modified Passey method: A resistivity based method.
- Faust: A sonic based method.

DCA: Type well curves
In this video I demonstrate how to generate a well set filtered by a number of criteria and generate a multi-well type curve. Before starting this video you should already know how to load your data and create a DCA project. If not, please review those videos. Type well curves are generated by creating a decline that represents data from multiple wells.
DCA: Loading Production data
In this video I demonstrate how to load production and well header data for use in a decline curve analysis project. The first step is to gather your data. You’ll need: Production data – this can be in CSV, Excel, or IHS 298 formats. For spreadsheet formats you’ll need columns for API, Date, Oil, Gas, Water (optional), and days of production for that period (optional). Well header data – this can be in CSV, Excel, or IHS 297 formats.
