This work is a continuation of the work described in a previous paper, however, to achieve improved performance, major changes were introduced, both in the performance, major changes were introduced, both in the theory and in realization of the algorithm. The central idea of the new work is the formulation of a number of rules of visual correlation. These rules are then applied in attempts to find acceptable correlations. The sequence of the application of the rules is dependent upon the character of the data, and the process continues until a good correlation is found. In contrast, in previous work, there were fewer rules, and all of them were applied together in a general optimization scheme. This new approach gives the program additional flexibility, which lets it process data that program additional flexibility, which lets it process data that could not be handled previously, and also results in a much more practical running time. Another advantage of the new algorithm is the possibility of a number of options in the level of detail of the dip analysis - from very general tvery fine.IntroductionThis introduction describes in general the approach taken in this work for implementing the rules of visual correlation. As is well known, visual (sometimes called optical) processing of dipmeter logs remains the standard of quality processing of dipmeter logs remains the standard of quality and the benchmark for evaluating the performance of new dipmeter processing programs. Even though some recently developed programs have reached the level of detail which is beyond what is normally produced by visual processing - this is only a matter of time and practical convenience using expanded plots and given ample time, a dipmeter analyst could verify every valid correlation found by a program. Therefore, analysis of the process of visual program. Therefore, analysis of the process of visual correlation can still be used for designing dipmeter processing programs. processing programs. This type of analysis has previously led to the design of a dipmeter processing algorithm which was based on the techniques of segmentation trees and optimization. This earlier algorithm was an attempt to break away from correlation schemes that were either too general, and could not see the detailed information, or that were too specific, and saw detailed dip information, but, being based on the analysis of detail, would sometimes miss the general picture, The earlier approach was in many aspects successful, and resulted in an algorithm that produced event correlations, and permitted seeing both produced event correlations, and permitted seeing both gross (structural) and detailed (stratigraphic) dip pictures. More information on the optimization techniques used in the previous algorithm can be found in reference 7.However, the optimization approach used in the previous algorithm had some disadvantages. One of them was that optimization process used took a very long time to complete, due to the large number of possible combinations of correlations being considered. This limitation that the program had to consider excessive potential combinations - led to another disadvantage: additional correlation possibilities, which were needed to process some special types of recording, could not be considered in the algorithm, since the search space was already close to a practical limit.Therefore, in this work a new approach has been taken.P. 239 Keywords: srather, upstream oil & gas, interpretation, society of petroleum engineers, subroutine segmnt, algorithm, log analysis, rule-based approach, displacement, dip computation Subjects: Formation Evaluation & Management, Information Management and Systems, Open hole/cased hole log analysis, Artificial intelligence This content is only available via PDF. 1988.
