WebIf the type of organic matter is known, the level of organic maturity (LOM) can be determined from a variety of measurements such as vitrinite reflectance, thermal alteration index (Tmax) or Rock-Eval pyrolysis. In over-mature shale reservoirs with LOM values greater than 10.5, the limit of calibration of maturity to TOC is reached. [5] WebFeb 4, 2024 · Thermal maturity; The first two components are products of the depositional setting. The third is a function of the structural and tectonic history of the province. Determining source rock potential. The quantity of organic matter is commonly assessed by a measure of the total organic carbon (TOC) contained in a rock.

Extracted Tmax numbers are much more reproducible than unextracted Tmax values due to the lack of S1 interference with S2.
