Author: Grecco C.B.

Abstract: In the production history matching process, the reservoir simulation model is modified in a way that it becomes consistent with production data, keeping the observed restrictions of the geological characterization phase. This technique is complicated arid limited, mainly in mature fields, when the production history is not reliable, or in the beginning of production, when there are only a few observed data and uncertainty are higher. The research of new technologies has resulted in the development of new saturation data acquisition tools, such as 4D seismic and. TDT/TDM logging tools. The great challenge is how to use this data in a way to improve the petroleum production. History matching methodologies with saturation data from 4D seismic start to be found in literature but there are no projects that utilize saturation data obtained from well logging. The advantage of the logging tools is the data accuracy but, on the other hand, it is limited to a few feet around the wells. The main objective of this project is to integrate the traditional history matching process with logging saturation data obtained from the new logging tools, developing a new methodology to generate trustier simulation models and more reliable production forecasts. The saturation data is utilized as a new parameter to be matched as well as an auxiliary tool to help to determine critical regions which will be modified. An assisted history matching methodology utilizing saturation data, streamlines and an optimization algorithm is proposed. The proposed methodology was applied to a case with a well-know behavior. Parameters of the process are studied and detailed, finding the best way to use the data. The model was also history matched with no saturation information and predictions of the matched models are compared, showing the benefits and restrictions of the new methodology.
