Figure 2. High resolution seismic profiles (see inset map for location within Lagniappe delta complex) show clinoform architectures typical of shelf-edge deltas. The high amplitudes in the lower parts of the clinoform packages reflect the presence of bubble-phase gas. These deltas contain reservoir facies ranging from massive distributary-mouth bar and channel sands to delta-front turbidites. The fluvial facies illustrated by X-ray radiographs is composed of gravel-rich sands while clean sand comprises the delta facies. These X-ray radiographed core samples were selected from the MP303 corehole (see inset map).
