SPE 69629 Dallas, Texas Society of Petroleum Engineers 2001 12/09/06 ; 02/10/01 In this work a methodology is developed in which is applied the advances of applications of seismic 3D (Variance Cube, Seismic Attributes, Three Dimensional Visualization, incorporating Well/Seismic depth cross sections, and others) in the evaluation of the field, integrating it with the disciplines of the geosciences to obtain a static model of the producing reservoir. This study is of great help in the reevaluation and interpretation of areas currently producing and also gives better definition and characterization of remaining prospective reservoir areas. The study area is from the middle portion of Lake Maracaibo, Western Basin of Venezuela, more specifically in the Seismic 3D cube of Block VIII. The dataset cube embraces an area of 265 Km2; comprised by approximately 700 Inlines and 1400 Crosslines. Later in the project the study was further detailed in a smaller cube of 112 Km2 in order to study the C-2 reservoir of Block VIII. In total there were 152 wells loaded in the database. Within the regional stratigraphic column, there were interpreted four (04) Seismic reflectors range from the Cretaceous period into the Miocene, and these reflectors show strong acoustic impedance and are of great areal extension, which are: Socuy member of the Creatceous Colon Formation, Guasare Formation(Paleocene), Top of Eocene Uncomformity and the Rosa Formation (Miocene). Subsequently the C-2 and C-3 Sands of the Eocene Misoa formation were interpreted in VIII Block. The objective is to study the C-2 Sand of Block VIII which contains 190.7 MMBLs POES (original oil in place), remaining oil in place of 11.7 MMBLs, and accumulated production of 33.4 MMBLs with an oil retrieval factor of 23.65 % and oil of gravity of 27.5° API. This sand is segregated into six (6) separate reservoirs in this block. The application of this methodology helped in finding new development prospects and increased the net recoverable barrells in the area of study.
