Strategy For Developing And Calibrating Shale and Mudstone for Unconventional Resource Exploration And Production On Drill Core And Cuttings Using Handheld X-Ray Fluorescence Units and the Adaptation to an Automated Core Scanner

Abstract

This poster illustrates the approach used by Harry Row, University of Texas, Austin to establish a dedicated calibration for shale on a pXRF unit to enable chemo stratigraphy. Starting from the selection of representative in type reference samples, developing a suitable sample preparation to the calibration and matrix correction, we will step thru the process. The published method (1) is validated against ICP and WD-XRF on the same samples and has been applied successfully in the Texas and Bakken shale plays. Using a automated core scanner for the pXRF which includes the ability to work with a Helium purge improved performance is achieved for the light elements as well as the ability to increase the resolution of the scanning.
