Multi-evaluation core logger

Abstract

Method, system, and apparatus are disclosed for conducting multiple types of evaluations on a core sample. The multiple types of evaluations allow core samples from historically problematic formation materials, such as those having consistently high gamma responses, to be reliably positioned downhole. Disparate types of evaluations may be obtained in a single pass of the core sample, thereby reducing the number of test environments imposed on the core sample. Where more than one pass is desired, different evaluations may be performed without changing out detectors and measurement devices. Evaluations that are normally acquired in a wellbore using a wireline tool, as well as those that cannot be easily conducted downhole for various reasons, may instead be performed on the core sample. Such an arrangement provides a more robust and flexible way of analyzing core samples than existing techniques.
