ALS offers services in Total Organic Carbon (TOC-LECO) and Hawk Pyrolysis; two geochemical methods that are used to quantify the organic content of rocks. These are powerful techniques to identify zones with highest potential for production and to assess the expected production of each organic interval.
Total Organic Carbon (TOC-LECO), Total Carbon (TC-LECO) and Total Sulfur
Total Organic Carbon (TOC-LECO) and Total Carbon (TC-LECO) analysis is measured using a LECO C-230 Carbon Analyzer for rapid, precise, and reliable results. Total Sulfur analyses is also offered in-house at our Oil & Gas laboratory. These three methods provide a precise and reliable determination of organic and inorganic carbon and sulphur abundance on a variety of organic and inorganic materials: coal, coke, oil, drilling cuttings, soil, sediment and cement.
HAWK Programmed Pyrolysis is a method to measure richness and thermal maturity of potential source rocks. A geologic sample is placed in an enclosed vessel and is progressively heated under inert gas flow. The organic content is pyrolyzed in the absence of oxygen, then combusted. The amount of hydrocarbons are monitored by a flame ionization detector (FID). The method is completed by oxidation of the residual rock recovered after pyrolysis under oxygen. During pyrolysis and oxidation, the carbon monoxide and carbon dioxide released are monitored by an infrared cell. The acquisition parameters could include S1, S2, Tmax, S3, S3CO, S3’, S3’CO, S4CO, S4CO2, and S5.
