Description/Abstract The Cano Limon field is located in Colombia, and had a STOIP of 2 bbl.^A three-dimensional geological reservoir model has been constructed with the computer program MONARCH, on the basis of data from 24 wells, The model includes the high net/gross fluvio-deltaic M1 reservoir, and the overlying C5 reservoir, which consists of an undeveloped low net/gross coastal plain sequence.^The modeling project was restricted to an area of 9 x 3 km.^The Cano Limon model is represented by a matrix of 1.75 million volume elements (voxels) each measuring 50 x 50 m horizontally and 0.6 m vertically.^At each voxel the model indicates whether shale or sand is present.^If sand is present, MONARCH differentiates between three types of genetic sand body types: channel, mouth bars, and crevasse splays.^Correlatable sands are mapped using a deterministic approach and the lateral extent of noncorrelatable sand bodies is derived using statistical distributions of width-thickness ratios.^These distributions are directly derived from the information given by Cano Limon well data about the degree of correlativity of the sand bodies.^MONARCH combines structural information, as derived from seismic, with information about sand body orientation as provided by dipmeter data oriented cores, and seismic amplitude maps.^In the case of Cano Limon which is produced by a strong natural water drive with an unfavorable mobility ratio of 11, this level of integration helps provide reliable guidelines regarding the development of the field.^Although the upper C5 reservoir is yet undeveloped, the 24 production wells can hypothetically be completed in the MONARCH models.^Calculations indicate that 60% of the total oil-bearing reservoir volume in the C5 reservoir is connected to 23 of the 24 wells.^MONARCH allows the geologist to input as much geological knowledge as is appropriate in the three-dimensional reservoir model.
