About This Lecture
This technical lecture explored how drawdown pressure transient analysis (PTA) can provide rapid, physics-based well inflow characterisation without production shut-ins, additional wellsite hardware or prior production history.
Lawrence Camilleri presented practical applications using high-frequency pressure and rate measurements, including data from ESP-equipped wells, to evaluate reservoir behaviour, inflow performance and production optimisation opportunities.
Drawing on case studies from conventional and unconventional wells, the presentation addressed operational challenges such as slugging, crossflow and changing reservoir conditions. It also examined how combining PTA with rate transient analysis (RTA) can support pore volume estimation, reservoir surveillance and improved production decisions.
