Application of Extended Elastic Impedance Attributes to the Hassi Messaoud Field, Algeria

The Hassi Messaoud field is a giant oilfield in Algeria, producing since 1957. It is a complex field whose Cambro-Ordovician clastic reservoir exhibits significant lateral heterogeneities, thickness variations caused by Hercynian erosion, and igneous rocks intruded into and extruded above the reservoir. 3D seismic data, in addition to providing structural information, is being used to help delineate development well locations. This study describes the contribution of extended elastic impedance attributes to field development in the Hassi Messaoud field.
