Abstract
A method includes obtaining a first time series of a first well parameter from the first well and a second time series of a second well parameter from the second well, processing the first time series to obtain a processed first time series, filtering the second time series by removing dynamic variations from the second time series to obtain a filtered second time series representative of static variations of the second time series, and determining a correlation between the processed first time series and the filtered second time series at various time shifts between the processed first time series and the filtered second time series, and determining a maximal correlation coefficient and a time shift at maximal correlation between the processed first time series and the filtered second time series, the maximal correlation coefficient being representative of the connectivity between the first well and the second well.
