The Formation Evaluation in Cased Hole Wells Training Course by Institute For Oil & Gas Training develops the specialist technical capabilities required to evaluate reservoir properties, monitor fluid saturation and assess remaining hydrocarbon potential in completed oil and gas wells. The programme focuses on Formation Evaluation in Cased Hole Wells, equipping industry professionals with the knowledge to interpret cased hole logging measurements, apply pulsed neutron measurements, conduct behind casing evaluation and support effective reservoir surveillance.
As oil and gas assets mature, operators face increasing challenges in maintaining production, identifying remaining hydrocarbon reserves and understanding changing reservoir conditions. A significant proportion of producing assets operate through existing casing and completion infrastructure, making conventional open hole measurements unavailable or impractical for many evaluation requirements. Cased hole formation evaluation provides an essential approach to obtaining additional subsurface information without relying exclusively on new wells or repeating the original open hole logging programme.
For reservoir management teams, understanding formation properties behind casing is essential for assessing water movement, identifying changes in hydrocarbon saturation, evaluating producing intervals and determining opportunities for production optimisation. Pulsed neutron logging technologies provide valuable information about formation fluid conditions through casing, supporting reservoir saturation monitoring and the assessment of changes in oil, gas and water distribution. These measurements contribute to a more complete understanding of reservoir behaviour throughout the producing life of a well.
The course examines the physical principles, measurement techniques and interpretation methods associated with cased hole formation evaluation. Participants develop an understanding of sigma measurements, neutron capture, carbon-oxygen logging, thermal neutron decay and other pulsed neutron applications. The programme also addresses the influence of casing, cement, wellbore fluids, completion configurations and formation characteristics on measurement responses.
A major focus is the interpretation of reservoir saturation changes between successive logging surveys. Production and injection activities alter reservoir fluid distributions, creating the need for reliable evaluation methods that distinguish genuine saturation changes from measurement variations and environmental effects. Participants examine how repeat logging, reference measurements and integrated interpretation support remaining oil assessment and identify intervals requiring further investigation.
Behind casing evaluation also plays an important role in understanding reservoir connectivity and production performance. The course explores the relationship between cased hole measurements, open hole log interpretation, completion information, production records and geological models. This integrated perspective enables professionals to interpret formation responses in the context of actual well conditions rather than treating individual logging measurements as independent indicators.
The programme addresses the practical challenges of selecting appropriate logging technologies, planning evaluation programmes, assessing measurement quality and recognising interpretation limitations. Particular attention is given to the effects of borehole conditions, casing characteristics, cement placement, formation lithology, salinity and fluid composition on logging responses. Understanding these influences strengthens confidence in technical conclusions and reduces the risk of making operational decisions based on incomplete or misleading interpretations.
For organisations managing mature fields, water injection projects, enhanced recovery operations and complex producing assets, reservoir surveillance provides an important foundation for maintaining production efficiency. Repeated cased hole measurements help identify changing reservoir conditions, evaluate fluid movement and compare current formation responses with historical measurements. These capabilities support decisions concerning production allocation, water management, selective completion interventions and further reservoir development.
Institute For Oil & Gas Training delivers this programme for professionals involved in petrophysics, well logging, reservoir engineering, production technology, subsurface interpretation and field development.
