DETERMINATION OF MINERALOGY AND LITHOLOGY FROM ELEMENTAL DATA

原文（中国語）

Disclosed herein are methods and systems for determining downhole formation lithology after calculating the mineralogy of the formation based on acquired elemental data in a specific order. More specifically, the elemental data may be acquired using a downhole geological tool. The elemental data are then used to calculate the formation minerals, which, in combination, are then used to determine the formation lithology classifications.
