Capstone: A CO2 Storage Project

Part 14, Chapter 14: Capstones and Final Assessment

Simulation with the Goal Flipped

A storage project is reservoir simulation run forward in time with the goal flipped from extraction to permanence. The reservoir has a finite capacity set by its pore volume and quality; injection fills it year by year.

Capacity and Security

Pushing the rate past what the capacity and seal can hold risks over-pressuring and leakage. After injection stops, the trapping mechanisms keep working, so the securely held fraction climbs for decades.

The Same Physics, a New Purpose

Pore volume, flow, pressure, and trapping, the same physics this course built for production, now serve to keep carbon underground. That is where reservoir modeling is heading.
