F004 SEISMIC MULTI-ATTRIBUTE ANALYSIS FOR LITHOLOGY DISCRIMINATION IN THE GANSO FIELD OFICINA FORMATION EASTERN VENEZUELA Abstract 1 Even extensively drilled and supposedly well-understood fields have the capacity to surprise. Whilst drilling a fairly routine development well in the Ganso field Oficina Basin Eastern Venezuela ENI Dación discovered a new accumulation reservoired in a high quality channel facies sandstone 30ft thick and full of relatively light oil.
