Geological core logging manual

 · Core description. Core slab photo. Careful examination and recording of information from continuous cores provide critical data for stratigraphic correlation, environmental interpretation, and wireline log calibration. Core plugs provide samples for analysis of porosity, permeability, fluid saturation, and a host of compositional and textural. This initial core logging effort focuses on cores retained from ~– ft drilled depths. Additional cores have been retained from shallower depths, primarily from boreholes near the Clifton Court Forebay in the southern delta (fig. 1), but detailed geologic logs for these additional shallow cores are not presented herein. Methodology. form. Breaks believed to be machine induced, or purposely made so that the core could fit in the core box, will be so annotated. The intervals by depth of all lost core and hydrologically significant details will also be noted. This information will be recorded at the time of core logging.

geologic designs are evaluated and the corresponding Rock Core Logs developed. The standardized charts and tables herein, used as descriptive aids in the evaluation procedures, are adopted from various organizations, such as the U.S. Department of Interior, Geological. FIELD MANUAL For example, “maximum particle size 35 mm” or “maximum particle size mm” are the correct format and size increment. Table is a checklist for log descriptors.
