Computer Methods of Diplog Correlation

Abstract

Abstract This paper presents an automatic Diplog processing system that incorporates several new processing system that incorporates several new techniques and allows alternative processing paths. The rationale for selecting the product-moment method as the primary correlation technique is given, and the algorithm for variable window-length correlation and infinite-clip methods discussed. In the screening section, several approaches to grading and screening of picks to improve the appearance of the machine-correlated Diplogs are discussed. The derivation of flexible vector analysis equations for dip calculation is also presented. Introduction Modern logging technology appears to be on a definite trend toward the recording of well log data on magnetic tape. The use of digital tape for Diplog data processing has been increasing for several years and will continue to become more significant. The use of magnetic tape for processing theoretically makes the turn-around time faster and makes screening and filtering of large amounts of data feasible. Processing of digital tapes can take any of several routes, some better than others for a particular set of conditions. In this paper, we particular set of conditions. In this paper, we present several of the possible approaches to present several of the possible approaches to processing the data and explain the rationale for processing the data and explain the rationale for choosing a particular one. In addition, several approaches that we feel are both new and useful are presented.
