EXECUTIVE SUMMARY
Secondary Recovery Processes & Reservoir Pressure Maintenance is a comprehensive professional training program focused on improving hydrocarbon recovery beyond natural reservoir depletion. The course examines water injection, gas injection, pressure maintenance, displacement mechanisms, reservoir surveillance, and performance optimization. Participants explore how reservoir properties, fluid behaviour, well patterns, and operating conditions influence secondary recovery efficiency. The program explains microscopic displacement, macroscopic sweep efficiency, mobility control, breakthrough behaviour, and injection performance. Particular attention is given to waterflood design, gas injection strategies, reservoir pressure support, and production response evaluation. Participants learn to screen reservoirs, select appropriate recovery methods, and develop technically sound injection programs. Practical applications demonstrate material balance, fractional flow, pattern analysis, injection allocation, and performance forecasting. The course also addresses operational challenges, surveillance techniques, conformance problems, and opportunities for recovery improvement. By completion, participants will be equipped to support effective secondary recovery projects and maximize long-term reservoir value.
INTRODUCTION
Primary production rarely recovers the full volume of hydrocarbons originally contained within a reservoir. Declining reservoir pressure eventually reduces production rates and limits the effectiveness of natural drive mechanisms. Secondary recovery processes introduce external fluids to maintain pressure and displace remaining hydrocarbons toward producing wells. Water injection is widely applied because of its availability, effectiveness, and compatibility with many reservoir environments. Gas injection can also provide pressure support and improve displacement under suitable geological and fluid conditions. Successful secondary recovery requires integrated understanding of reservoir geology, fluid properties, displacement behaviour, well patterns, and surface facilities. This course connects fundamental recovery principles with practical design, surveillance, forecasting, and optimization techniques. Participants evaluate injection performance, production response, sweep efficiency, breakthrough risks, and reservoir management alternatives. The program enables professionals to make better decisions that increase recovery, improve reservoir performance, and extend productive field life.
