Abstract: Application of Dip-Related Measurements to a Complex Carbonate-Clastic Depositional Environment

Ed Bigelow1

Wyoming Geological Association: 1982 Luncheon Meetings Casper, Wyoming: Abstracts of Papers

Dip-related measurements help define a shelf-type carbonate environment.

Analysis of cores is the standard method for determining lithology and sedimentology of formations penetrated in a well. In the past decade, the trend of using modern log data has developed, not only to predict general petrophysical parameters, but also to describe reservoir geometry and depositional environment.

Several authors have described methods for determining lithology, texture and sedimentology, provided the necessary log measurements were available. These systems are limited by the complexity of the rock and its environment.

With the exception of carbonate reefs, this author has not found published information dealing with the use of log data to describe a carbonate depositional environment. For this reason, the objective of this article is to provide some evidence that curve shapes and patterns from computed dip information can be applied, as necessary, to describe such environments.

An application of previous techniques is extended here to a carbonate depositional environment, using only the information from dipmeter data. It is compared to lithostratigraphic studies from cores, well cuttings, and the more routine log measurements.
