The main reservoirs of Denise Field are Pliocene Denise sands which are divided into three different reservoirs: upper Denise sand, middle Denise sand, and lower Denise sand. The two main reservoirs in terms of areal extension and production are the upper and lower Denise sands. These reservoirs are mainly composed of sandstone of turbiditic origin, which are expressed as bright spot seismic amplitude anomalies as one of the most common Direct Hydrocarbon Indicators (DHI), with a clear flat spot seismic feature representing the gas water contact in the proven area. While faraway about this area it is problematic to delineate the reservoirs, due to the low reflectivity that produced by the huge thickness of Pliocene shales. Similarly, the low resolution of shallow interval with missing data due to the existence of the drilling platform in time of acquiring the seismic data.
