ABSTRACT

The importance of core analysis in well completion and reservoir evaluation is well established. The physical properties of cores that are measured in core analysis and the fluid mechanics of flushing by the drilling fluid and fluid expulsion by gas expansion as the core is brought to the surface have been treated in several previous papers.(FOOTNOTE 1, 2) 2 The conventional method of analyzing "plug" or small samples, representative of an interval of core, will be discussed briefly, but the whole core analysis technique of analyzing all of the core recovered from an interval will be treated in somewhat more detail. The application of whole core analysis to some Lower Cretaceous formations is discussed. The possibilities of data analysis that are afforded by rapid electronic data handling equipment are discussed, and average data and data correlations for several Lower Cretaceous formations are presented.
