Figure 55. Schematic <strong>of</strong> depositional history <strong>of</strong> Mars-Ursa intraslope basin showing some<br />
<strong>of</strong> the major reservoirs (Adapted from Meckel et al., 2002).<br />
The well log and seismic expressions <strong>of</strong> some <strong>of</strong> the significant reservoirs in the Mars-<br />
Ursa intraslope basin can be seen in the well logs (Figure 56) and seismic 2-D pr<strong>of</strong>ile<br />
(Figure 57) below. Meckel’s (2002) interpretation <strong>of</strong> logs from Mars, Princess, and Ursa<br />
A4 were extended to the Ursa 1 well and integrated with Hilterman’s (2001)<br />
interpretation <strong>of</strong> fluid presence. In this well the green is oil and the red is gas. Yellow<br />
intervals represent sandy intervals with low gamma readings while high resistivity.<br />
Interpreted sheet sands such as Lower Yellow, show high corelability between wells and<br />
channels such as Above Magenta show low corelability between wells.<br />
