Leak detection system and method for monitoring leaks in underground and aboveground storage tanks, pipelines or other containments, including single, double or triple wall containments are provided. A leak detection apparatus includes an oxidation chamber, a chemical marker concentrator, a mass spectrometer (MS) ion trap and a scroll vacuum pump. Vapor samples carrying marker chemicals introduced into a tank, pipeline, or other containment are injected at sample injection point into an oxidation chamber. Oxygen from an oxygen source is fed into oxidation chamber to destroy or oxidize contaminates such as hydrocarbons in the vapor without destroying or oxidizing the chemical markers. Effluent from the oxidation chamber is passed to an elongate conduit with a metal foil or screen suspended within the conduit. The marker chemicals are attracted by a chemical coating on the foil/screen and released by heating the metal. The released marker chemicals are fed into a mass spec ion trap for leakage analysis and results.

The apparatus includes a pyrolysis chamber configured to receive and hold within an interior space a volume of an aqueous fluid and to maintain a pressure within the interior space for a duration of an experimental period when a removable head is in a closed position. The apparatus includes a sample basket assembly comprising a plurality of baskets attached to the removable head by one or more rods. Each basket is configured to receive one or more source rock samples. The sample basket assembly is configured such that, when the removable head is in the closed position and the one or more source samples are disposed within each basket, the samples suspended in a substantially stationary position above the floor.

Methods and systems are disclosed. The method may include obtaining a first plurality of hydrocarbon source rock samples from a first well and a second plurality of hydrocarbon source rock samples from a second well, each well penetrating a portion of a subterranean region. For each of the first and second plurality of samples obtaining a set of kinetic parameter values, including a discrete distribution of activation energy and a common frequency factor and determining a weighted average activation energy value from the distribution. The method may further include identifying a first chemostratigraphic segment of the first well and a second chemostratigraphic segment of the second well, each based on the weighted average activation values; determining a correlated stratigraphic unit and mapping organofacies based on the first the second chemostratigraphic segments; and predicting hydrocarbon generation, retention and expulsion and determining a drilling target within the correlated stratigraphic unit.

A method for classifying at least two or more resins, the method comprising: a purification step of removing volatile components by subjecting resins to be classified to a heat treatment at a temperature lower than each decomposition temperature; a decomposition step of subjecting the resins to be classified to a pyrolysis treatment at a temperature higher than each decomposition temperature to obtain pyrolysates of the resins; an analysis step of separating and analyzing the pyrolysates using a two-dimensional gas chromatograph mass spectrometer; a table creation step of creating a table by performing assignment of peaks appearing in each two-dimensional chromatogram obtained after the analysis step and alignment between the two-dimensional chromatograms; and a classification step of classifying resins by performing multivariate analysis based on the created table.
