Abstract: A method for determining a mineralogical composition of a geological formation sample includes measuring a mineralogical composition of the sample and measuring an elemental composition of the sample. The mineralogical composition is processed to compute a predicted elemental composition of the sample based on known elemental compositions of predetermined minerals. The measured mineralogical composition is corrected to obtain a corrected mineralogical composition which is in turn processed to compute a corresponding corrected predicted elemental composition of the sample. The measured elemental composition is compared with the predicted elemental compositions to obtain error indicators. The error indicators are compared and evaluated to selected and output one of the measured or corrected measured mineralogical compositions.

Abstract: The disclosure relates to a method of analyzing at least a rock sample extracted from a geological formation. The method comprises: heating the at least one rock sample under inert atmosphere with a temperature below 300° C. and with a flow of inert gas to remove contaminants, analyzing at least one of the decontaminated rock samples and determining at least a property relative to non-volatile organic matter contained in the geological formation based on the analysis.

Abstract: A system for analyzing gas extracted from drilling fluid is provided. In one embodiment, the system includes a gas extractor having a gas extraction chamber within a gas extractor housing and a gas outlet for gas separating from the drilling fluid within the gas extraction chamber. Further, the system includes a gas analyzer, which has an optical analyzer and an optical source that are situated outside of the gas extractor. A gas analysis zone is in fluid communication with the gas extraction chamber and is optically connected via at least one fiber optic cable to the optical source and the optical analyzer. Additional methods, systems, and devices are also disclosed.

Abstract: The general field of the invention is that of matter-wave gravimeters. The gravimeter according to the invention comprises at least: means for generating, for capturing and for cooling a cloud of ultra-cold atoms; means of transferring the atoms into a superposition, with equal weights, of a first internal electronic state called state |1>) and of a second internal electronic state called state |2> comprising the application of at least a first microwave field and of a radiofrequency field; means for separating the atoms into two wave packets for a given period of time under the effect of at least a second microwave field, the said separation leading to a phase-shift associated with the local gravitational field; calibration means allowing a “magic” magnetostatic field to be determined for which the difference in energy between the first internal electronic state and the second internal electronic state is independent, to a first order, of the fluctuations of the magnetostatic field.
