Well-to-well correlation can provide a correct determination of the spatial equivalence of rocks based on their petrophysical properties. Recently it has been applied as an effective tool in planning the development and production strategy of the oil and gas fields. This paper describes an approach to automated well-to-well correlation with the electrofacies derived by selecting, weighting, and combining well log data using the cross association method that can handle missing, shifting, thickening and thinning strata. Correlation with well logs in oversea field shows that this approach can make well-to-well correlation with well log data reliable. This procedure minimizes the subjectivity involved in the well-to-well correlation process. It can be used to make the correlation results more reliable and effective.
