Where Engineering Meets
the Deep Subsurface

I'm Tahir Chisti — a petroleum engineer (P.Eng, MASc.) specializing in Carbon Capture & Storage (CCS) and Underground Hydrogen Storage (UHS), based in Alberta, Canada.

My work sits at the intersection of subsurface reservoir engineering, regulatory compliance, and digital innovation. From conducting detailed technical reviews of CCS AER Directive 065 applications/class VI application review to building AI-powered sub-surface engineering tools, I bridge the gap between deep technical domain knowledge and practical, actionable solutions.

I've performed comprehensive regulatory reviews of major CCS scheme applications, identified critical flaws in MMV plans through independent engineering verification, and built interactive tools that make complex regulatory frameworks navigable for operators, engineers, and investors.

My vision: accelerate responsible CCS deployment by making regulatory expertise more accessible through technology.
