Rance Kretch, Rebellion Photonics – Houston, Texas

Rebellion Photonics offers its unique Gas Cloud Imaging (GCI) cameras that can image and quantify gas leaks in real-time video. Rebellion’s GCI system is available in both fixed for continuous monitoring and truck-mounted for periodic monitoring. The fixed GCI systems dramatically enhance an asset’s DCS systems and thereby reduce the need for unplanned maintenance or releases. Rebellion also offers a truck-mounted, all inclusive, GCI emissions monitoring service for meeting regulatory requirements and GHG emissions monitoring. The GCI is capable of differentiating among over 20 types of gases including hydrocarbons like methane and other dangerous gases like hydrogen sulfide. It is capable of continuously monitoring large areas and is inherently more reliable than any single point detection or sensor network. It’s also versatile in that it can be deployed in a variety of applications and environments in oil and gas drilling, completion and production with customers in upstream, midstream and downstream.

Current Leak-Detection-And-Repair (LDAR) Programs in the U.S.

Ken Garing, US EPA – Denver, Colorado

Ken has a chemical engineer degree and started his career in the refining industry.  From there he moved on to consulting engineering firms working on geothermal development and design projects in the Middle East.  He currently works with the US Environmental Protection Agency.  His EPA career has focused on air emissions from refiners and chemical facilities.  In the late 80s he was involved in the first LDAR inspections conducted by EPA.  He was the technical lead for the LDAR and Benzene Waste portions of the refinery global settlements.  Currently he is involved with the development of next generation remote monitoring activities.  

Smart LDAR - New Paradigm that Works

Derek Reece, ExxonMobil

Derek Reese has been relentlessly chasing down fugitive emissions and putting them back in the pipes for over 23 years at ExxonMobil.  Using his chemistry degree and military training as a U.S. Naval Officer, Derek has been a dogged pursuer of these wayward molecules and has been a staunch advocate for use of better technology and efficient paradigms to keep these organic escapees in their place.  Affectionately known as “a big air head”, Derek Reese has spent his career in environmental compliance and supervision at ExxonMobil refineries and chemical plants.  He has never met a carbon atom he didn’t like and always tries to help them find their maximum value in life.  His philosophy to young organic molecules is simple.  It is better to stay in the pipeline to productivity as a polymer, fuel, or useful medicine than to throw your molecular life away in the atmosphere and becoming just another ozone radical.
