Saturation Height Modeling module
Purpose
The Saturation Height modeling tools enable users to explore models of how saturation should vary with height above free water level (HAFWL) and how irreducible water saturation varies with rock quality.
Primary Outputs
The following curves are the primary interpretations made in this module.
| Curve Name | Description |
|---|---|
| SW_FOIL | Saturation from FOIL method |
| SW_RQI_SWH | Saturation from RQI method |
| SW_PERM_SWH | Saturation from Pc method |
| SWIRR_PERM_SWH | Irreducible saturation from Pc method |
| SWIRR_RQI_SWH | Irreducible saturation from RQI method |
| SWIRR_LUCIA | Irreducible saturation from Lucia method |
| SWIRR_FOIL | Irreducible saturation from FOIL method |

The SwH modeling module is a specialized module that allows a calculation of Sw based on capillary pressure data. This module is unique in Danomics in that it is required to process your capillary pressure using a Flow tool ahead of time as shown in the video.
This module can be help you determine where the free water level is in your reservoir when it is not observed and can help you constrain your analysis by understanding the irreducible saturation.
This module can also be used to feed into the CO2 storage analysis module which requires an input for the irreducible water saturation.
This method provides an alternative to / check-on resistivity-based water saturations.

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.
