Surveillance logging showing saturation data within a production well between 2008 and 2013. The gamma-ray, nuclear and bulk volume logs on the left show three distinct sand units. The time-lapse logs on the right show these units are sweeping from the base upwards. At 8760 ft TVDSS a 10 ft thick sandstone unit remains unswept as the sandstones above and below water out. The core at this interval has been interpreted as a channel margin, isolated from the channels above and below. This zone was subsequently perforated and produced dry oil for 3 years.
