Fuzzy Correlation Analysis, With an Application to the Transient Well Test

One purpose of a well test is to get reservoir parameters. The problem is how to analyze the transient well test parameters and find relationship between them. We present an effective method to analyze the correlation between the well test interpretation parameters, which is a combination of grey correlation analysis and fuzzy clustering. In particular, we use grey correlation analysis to describe the correlation between parameters, and use fuzzy clustering method to divide them into different categories according to the degree of the correlation between all parameters. A simple example shows the algorithmic strategies to implementing them. In the example, we consider six parameters and each of them contains 92 data points. The example presented in this paper shows that it´s a flexible and cost-effective quantitative analysis method for transient test parameters analysis, it is particularly suitable for analyze relevance of time series data.
