A laboratory device and method are adapted to subject a same rock sample to successive liquid treatments without any intermediary handling of the sample. The device combines a chamber comprising a first part fitted with an inlet for introducing a rock sample and liquid reagents into the chamber; a heater for regulating the temperature in the chamber and a plug fitted within an open port for protecting the chamber from an overpressure. The first part also comprises means for stirring the contents of the chamber including a liquid by introducing gas as bubbles into the liquid. A second part of the chamber is located under the first part and a selective filtering unit is interposed between the first and second parts of the chamber, the filter has a porosity selected for retaining organic material contained in the sample. A gas bubbling inlet is provided for introducing the gas into the liquid contained in the chamber and a valve controlled discharge opening is also provided for draining off liquid from the chamber.

Laboratory device and method for treating rock samples

A method for obtaining information relating to material contained in geological formations. According to this method; these geological formations are subjected to at least one flow of so called incident neutrons having a substantially well defined energy, the incoherent inelastic diffusion spectrum of the diffused neutrons resulting from the interaction of the incident neutrons with the material contained in the geological formations is established at least partially, and from this spectrum are inferred certain of the energy amounts frequently transferred between the incident neutrons and molecules of the materials contained in the formations, or vice versa.
