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. The steps in doing this are to:
- Generate a list of wells that have been filtered to the relevant formation, well attributes, and production histories
- Perform a decline that matches the history of that well set for the oil, gas, and/or water phases.
This process can be repeated for differing scenarios or sets of 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.

NMR Interpretation Module
Purpose The NMR interpretation module allows users to calculate porosity, bound and free fluids from the measure T1 and T2 distributions from NMR tools. Primary Outputs Discussion In oil and gas well logging, the $T_2$ distribution is used as a high-resolution "map" of the formation's pore system. While a standard porosity tool tells you how much fluid is there, NMR tells you where that fluid is trapped and whether it will flow.
