Abstract

Repeated site survey data acquired before and after an underground blowout that occured when exploration well 2/4-14 was drilled in 1989 are used to map the migration of gas from the deep reservoir into shallow sediments. We use 4D difference sections to map the extent and vertical position of gas being trapped in various overburden sand layers. A dedicated sand tank experiment is conducted to improve our understanding of gas flow through the uppermost layer situated 100 m below seabed. This laboratory flow tests are compared to videfilms acquired close to the well.
