Abstract
The unconsolidated reservoirs of the Genesis field have experienced significant production-related compaction since first oil in 1999. This compaction causes stretching in the overburden, and is visible as time-shifts between the monitor and baseline 4D surveys. We measured local time-shifts between these two surveys at every point in the volume, and took their vertical derivative to produce an interval estimate of the fractional change in traveltime, which we call the time-strain. Analysis of the time-strain volume reveals remarkable detail about the production and geomechanical response of the Genesis field.
