Abstract
The Puerto Colon field is located in the Putumayo basin in southern Colombia, South America, and is operated by Empresa Colombiana de petroleos (ECOPETROL), which is the national oil company. The field produces from the Cretaceous sandstones of the Caballos Formation and is estimated to contain approximately 90 million bbl of oil in place. The development of the field is not complete, and plans are currently underway to determine the extension of the reservoir. Enhanced oil recovery activities are also being considered. A integrated reservoir characterization technique is used to integrate the geological, engineering, and reservoir performance data to describe the reservoir and to develop an appropriate reservoir management plan. We have developed an approach using geological and engineering data to characterize hydraulic flow units within a particular geological facies. We have tabulated reservoir characteristics for each hydraulic flow unit, and we have re-evaluated the reserves for each well in the field. Our study also evaluates the different water-oil contacts found and considers the existence of hydrodynamic flow conditions by using regional maps and well logs, as well as pressure and production data. We have attempted to define the nature and influence of wettability effects and the impact of these effects on oil recovery. The performance behavior and the deliverability of wells in the Puerto Colon Field are evaluated, and recomendations are made for optimizing oil rate performance and recovery.
