Key Updates

The latest version, EASiTool 5.0, has several noteworthy improvements including:

A clean, modern, web-based platform featuring an enhanced UI/UX design
Parameter input using .xlsx files
Flexibility to opt for either SI units, or field units, based on preference
Integration of GIS maps for comprehensive output visualization
Introduction of area of review (AOR) estimation with probability assessments
Incorporation of Monte Carlo simulations to enable in-depth sensitivity analyses
Enhanced net present value (NPV) models with updated parameters
Substantial improvements to software runtimes

About the New Version

The new EASiTool 5.0 brings a significant advantage with a modern, updated web-based platform, eliminating the need for software installation. This new version also offers input and output functionalities through file (.xlsx) uploads and downloads. The users also have the flexibility to choose between SI units or field units, ensuring consistency throughout the tool. Using advanced analytical models for closed- and open-boundary basins, this tool enables users to obtain reservoir-scale storage-capacity estimates. The runtime is typically within seconds, making this version significantly improved and faster compared to previous versions. This accelerated, science-based estimation process facilitates a faster decision-making process and enhances efficient project planning.

EASiTool 5.0 comprises two different modules, tailored to different scenarios, and reservoir geometries:

User Given Inputs (Constant Injection/Extraction Rate): This module is designed for users who have preliminary plans for their CCS projects with specific well and reservoir geometries in mind. Users are required to provide well locations in UTM coordinates and define reservoir boundaries. This module offers special features such as pressure contour maps, CO₂ plume extension maps, and a Geographic Information System (GIS) map—a new addition to this version. Users may also assess the storage capacity and evaluate the AOR, using both pressure contour and GIS maps by specifying increasing values for critical pressure. With the aid of AOR and GIS maps, this allows users to make comprehensive evaluations for each project. This module provides flexibility by allowing users to tailor each analysis to their specific project and conditions.

Maximum Storage Capacity (Fixed, Bottomhole Pressure): This module caters to general injection estimation, based on reservoir properties. With this module, users can explore well flow rates and net present value (NPV; with an update module), under a maximum CO₂ storage-capacity scenario. The software will also output a well design scenario under the maximum NPV.

Users can also conduct a sensitivity analysis (SA) for both modules. Similar to previous versions, the SA offers useful tornado chart features. Exciting additions include a Monte Carlo simulation, allowing users to assess the impact of input parameters on capacity estimation (P5, P95 and mean values), and AOR evaluations with probabilities, which can be visualized on GIS/contour maps.

These powerful functionalities, offered by EASiTool, yields a more holistic approach that helps a team make well-informed choices. Informed decisions, based on robust scientific results, enable more effective and successful implementations of carbon-storage initiatives.
