Welcome to Danomics: DCA
Getting Started with DCA
This guide will demonstrate how to create a new decline curve analysis (DCA) project, customize your layouts, style plots, filter to relevant data sets, set global constraints on your declines curves, calculate economics, perform manual declines, and generate multi-well type curves.
Sample Data
For this tutorial you will need well header and production data. You can download them using these links:
- Well log data
- Well header data
- Formation tops data
- Production data (CSV format / Excel format)
- Wyoming Counties Shapefile and Projection
- Wyoming Townships Shapefile and Projection
Step 1: Loading Data
To get started you will first need to upload some data to Danomics. In the video below we show how to upload well log, well header, well tops, production, and shapefile data.
Step 2: Creating a new DCA Project
In this video we demonstrate how to create a new DCA project, select your databases, and update the layout.
Step 3: Setting Filters, Constraints, and Economics
In this video we demonstrate how to filter down to the well set of interest, set global constraints on your decline curve analysis, and set up economics.
Step 4: Manual DCA and Multi-well Type Curves
When you create a new DCA project all the wells are automatically forecasted using your global constraints. In this video we demonstrate how to perform manual overrides to your production forecasts. I also demonstrate how to generate multi-well type curves to forecast your production in wells with short production histories.
Step 5: Creating Multi-well Type Curves
In this video we demonstrate how to generate multi-well type curves to forecast your production in wells with short production histories.
Step 6: Exporting Data
In this video we demonstrate how to export your results.
Summary
Congratulations on completing the Welcome Guide for decline curve analysis in Danomics. Although there is a lot more that can be done with Danomics DCA the knowledge you have taken from the videos should provide you with the fundamentals needd to make meaningful DCA interpretations.

Quick Start Module
Purpose The Quick Start module is designed to help users quickly set dozens of common parameters by selecting a handful of basic options from dropdown menus. Parameters There are three parameters that are set on a zone-by-zone basis and two parameters that are set on a full-well basis. These are as follows. Discussion The parameters are linked to what are called named_defaults in the software. These are collections of defaults that can be set through assigning a single parameter.
Sample data to get started

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.
