Thermal maturity can be determined through vitrinite reflectance performed on particular microfossil types. It controls the hydrocarbon type produced and commonly the type found in a rock interval. Qualiterra provides microfossil based vitrinite reflectance methods that will determine the thermal maturity of the rock body. If requested we will combine this data with pyrolysis based TMAX data to provide direction and understanding when attempting to assess an unconventional source rock hydrocarbon play.
