The Multiwell Faciolog computer process uses a multivariate analysis technique which integrates all types of data from a group of wells and reduces the information to one or 2 key displays. Four cored wells with similar logging suites were selected for study, Hartzog Draw Unit (HDU) Nos. 5308, 5297, 5294, and 5296. The logs were corrected for environmental effects and normalized. The Multiwell Faciolog data base, containing the average log responses for each electrofacies, was constructed from a key well (HDU No. 5308). Geologic information was used to describe each electrofacies stored in the data base, and each of the remaining wells was processed through the Multiwell Faciolog chain and displayed in a lithologic-column format. The advantages of the Multiwell Faciolog technique are that voluminous data, including wireline, geologic, and reservoir information, can be integrated into one or 2 key displays. This program also allows the interpreter to adjust and modify the data bases, as necessary, with the addition of each new well.
