Abstract
An insert apparatus for use in a test formation for a downhole nuclear spectroscopy tool includes an outer liner, and an inner liner defining a cylindrical borehole having a diameter such that the downhole nuclear spectroscopy tool is receivable therein. There is fill material between the outer liner and the inner liner, the material including a formation base material and an elemental standards material. The outer liner, the inner liner, and the fill material are configured such that an elemental standard measurement derived from a test using the insert apparatus is equivalent to an elemental standard measurement from a selected formation.
