Multi Azimuth Imaging of an Oil-bearing Faulted Sandstone Reservoir: A Nigeria deep offshore Case study

Abstract

The first depth velocity model over the field was created in 2011, using data acquired in 2008 as part of a high definition (HD) survey collected on a 6.25 x 12.5 binning grid with relatively shallow streamer and gun depths (5 m and 6 m respectively) aimed at maximizing the signal bandwidth and spatial resolution of the faulted sandstone reservoir. Here we present further work updating the 2011 model by combining the 2008 HD survey with an earlier 1997 regional survey to achieve a dual azimuth reprocessing.
