Abstract
One of these challenges is Carbon Capture and storage is guaranteeing minimum leakage condition in the reservoir, some researches indicate that even small leakage would impose a severe economic risk to the operation and harsh environmental damages. In order to assess those impacts, controlled leakage experiments were performed in the recent past aiming also in determining detection capabilities. The use of passive acoustic monitoring is proposed as the first layer of remote detection sensors for gaseous leakages in underwater operations, as during the formation of gas bubbles in water, a known signal is generated. Nevertheless, no data is available to assist in the development of passive acoustic leakage detection methodologies. Aiming at this gap, our group planned and performed controlled leakage tests at “Baia de Santos” to obtain the audio signals for different leakage conditions and distances between leakage sources and sensors. This paper describes the experimental campaign design, its methodology, and the results allow us to start understanding the acoustic emission behavior of bubble plumes.
