In 1988, 550 square km of 3D seismic data were acquired in the Sur Del Lago area. The aims of the survey were (1) To better define structures already identified from the existing 1 [times] 1 km 2D seismic grid at the level of potential Cretaceous limestone reservoirs and (2) To further study the prospectivity of potential structural and stratigraphic traps within the Tertiary section. Detailed interpretation of the 3D survey using an interactive workstation led to an improved structural definition at the Cogollo limestone level and the identification of fault related inversion lineaments and basement related Cretaceous limestone structures. Based upon the new seismic interpretation a 4 well exploration project was planned. The new program commenced with the drilling of exploration well SLA-7-IX in 1991 which proved commercial amounts of hydrocarbons in the western part of the area. Detailed information collected from the exploration wells includes a comprehensive electric log suite, ditch cuttings and vertical seismic profiles. The information is being used as detailed lithological, stratigraphic and seismic data input for velocity modeling, ray trace modeling, seismic attribute analysis, and reservoir characterization software in order to further understand the structural and stratigraphic potential of the area.
