<p> Source rock kinetics have become increasingly important when defining kerogen maturity and building basin models. Recent studies have suggested that the activation energies (E<sub>a</sub>) needed for these applications can be obtained using one-run open-system pyrolysis with a single heating rate and a fixed frequency factor (A). This method is thought to be faster and cheaper than using multiple heating rates with a varying frequency factor. In this study both methods were used to find the E<sub>a</sub> of seven organic-rich samples from the Eagle Ford Shale. Activation energies for the multiple heating rate method were calculated in accordance to the Kissinger method, while E<sub> a</sub> values for the single heating rate method were found using the One Run Fixed A (ORFA) kinetic software. The multiple heating rate method implemented heating rates of 5, 10, 20, and 50 °C/min, while the single heating rate method used a standard heating rate of 25 °C/min. Due to the use of a fixed A, the single heating rate method produced larger, more consistent values than the multiple heating rate method. However, these E<sub>a</sub> values were not always consistent with previous known values. When the fixed A value used in the single heating rate method was replaced with the A values obtained from the multiple heating rate method, E<sub>a</sub> became closer to those found using multiple heating rate method.</p><p>
