This paper explores the evolution of hydrocracking technology, focusing on techniques for producing cleaner fuels and enhancing reservoir management. It discusses traditional surface seismics and the advantages of microseismic monitoring, which enables permanent monitoring with advanced sensors deployed in wells. The integration of data collection into oilfield control systems allows for real-time insights, helping to manage reservoirs more effectively. The work emphasizes the market demand for clean fuels, particularly in Asia and Europe, where environmental considerations shape production strategies.

From wells… Profiting from knowledge
Surface seismics - today’s mature technology • Not continuous or real-time - need to deploy survey ships • Limited resolution - sensors are distant from reservoir
Microseismics - tomorrow’s technology • Permanent monitoring with sensors in the reservoir • Listen for naturally occurring low-level seismic events
Permanent logging - emerging technology • Advanced sensors permanently installed in the well • Fiber optic pressure & temperature sensors - high reliability, field-proven • Permanent electric logging sensors - under development
Information delivering data to the user • Integrating the downhole sensors into the oilfield control system
Knowledge Using microseismic information to better manage the reservoir Interpreting continuous microseismic event data. Detecting critical changes in the reservoir – water break-through, fault reactivation, etc.

Today’s hydrocracking market • 2000: Six ISOCRACKING units awarded to Chevron Lummus Global • Worldwide: Large catalyst resale and retrofit market • Asia/Middle East: Driven by distillate demand and environmental considerations • Europe/Americas: Strong environmental drivers Acceptable sulfur limits “Driving to Clean Air” 1980 2000 2010
Versatile process for green fuels and more… “Dirty” Feeds “Green Products” Hydrogen HYDROCRACKING Gasoline Jet fuel Diesel • Feedstocks for: • gasoline production (synergy with FCC) • lube oil manufacture • petrochemicals production VGO = Vacuum Gas Oil LCO = Light Cycle Oil from FCC CGO = Coker Gas Oil
Taking a current FCC-based refinery... FCC Heavy oil Gasoline and heavy products FCC = Fluidized Catalytic Cracking unit
High quality diesel ISOCRACKING ...into a clean fuels refinery via ISOCRACKING Major environmental impact Low sulfur gasoline FCC Heavy oil Balances diesel to gasoline. Enhances gasoline production
When middle distillate is preferred... Stand-alone ISOCRACKING does the job Benefits: • Converts heavy oils to high-quality jet fuel and diesel. • Reduces aromatics • Reduces sulfur, even from difficult heavy oil feeds • Produces highest yields of aviation turbine (jet) fuels and diesel fuels
