CO2 Storage Analysis Module
Purpose
This module allows users to evaluate the CO2 storage potential of a reservoir as well as the pressure available CO2 storage available.
Primary Outputs
| Curve Name | Description |
|---|---|
| CO2_DENSITY | Density of CO2 at reservoir PVT |
| CCS_STORAGE_CAPACITY | Cumulative summation of CO2 Storage Capacity |
| CCS_PRESSURE_AVAILABLE_STORAGE_CAPACITY | Pressure available cumulative summation of CO2 Storage Capacity |
Discussion
The module focuses on the "Storage" component of CCUS (Carbon Capture, Utilization, and Storage). Its primary goal is to take raw well log and spatial data and transform them into a Static Storage Capacity estimate.
Before making the calculation it is important to calculate the porosity and to evaluate the irreducible water saturation.
The module typically employs the industry-standard DOE (Department of Energy) methodology for saline aquifers and depleted reservoirs. It calculates the theoretical and effective storage capacity using the following logic:
G_CO2 = A * H * PHI * RhoCO2 * E
- A: Area of the storage complex.
- H: Net thickness of the injection interval.
- PhiE: Porosity.
- Rho_CO2: Density of CO2 at reservoir temperature and pressure (calculated using built-in Equation of State models).
- E: Storage Efficiency Factor, which accounts for the fact that CO2 will not fill 100% of the pore space due to water displacement and heterogeneity.
The Pressure Available CO2 storage capability further restricts the calculation to account for when there will be pressure restrictions on further injection.

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.
Making Log Calculations in a Flow
This articles provides an overview of how to use a Flow to before basic log calculations. To do this, the following Flow tools are used: LogInput >> Bring the log data into the Flow LogMath >> Perform some calculation LogOutput >> Writes the log data to a new log database. There can be as many LogMath tools added to a flow as one would like, and they can be added to existing Flows ushc as a Log Clean-up Flow. The LogMath tool is extremely flexible.
