I perform synthetic thermal maturation of organic matter by heat-treating mudrock samples (i.e., core and crushed samples) and isolated kerogen samples. The steps followed in the procedure are as follows, 1. The samples are heated in the oven at 4°C∕min to the required heat-treatment temperature under the flow of nitrogen 2. The samples are then isothermally heated at that heat-treatment temperature for an hour to endure that all the particles are uniformly heated at that temperature. 3. The samples are then cooled at 25°C/min till it reaches the the room temperature. 6.2 GEOCHEMICAL ANALYSIS OF KEROGEN
