Abstract
Summary
Most recent use of fibre optic sensing for downhole applications are associated with diagnostic applications. In this work, we focus on the time lapse evolution of perforated interval performances during several water injections cycle with application at the CO2CRC Otway research site. We compare the thermal signatures associated to the injection of cold water into a warmer reservoir for several wells. Results shows that the initial conditions and thermal state of the perforated interval prior to the water injection has an effect on the kinetics of the thermal response, yet no evidence on flow distribution across the interval were observed.
