Imaging through Mega Gas Clouds in Offshore Brunei

Imaging challenges at Gulf of Papua (PNG) and their solutions through high-end imaging technology

“…To image through the gas cloud, we also incorporated an Q anomaly model to compensate for the energy losses and phase distortion, in addition to the background Q. Inspired by previous successful cases (Lin et al, 2016;Zhou et al, 2014), we adopted the FWI-guided Q tomography for the anomaly absorption model. We first created a mask from the FWI velocity model according to its abnormal slowness.…”
