Temperature–depth profile
Thick coloured segments show where each geotherm crosses the immature, oil, wet-gas, dry-gas and over-mature zones; open circles mark the depths of the 60, 120 and 150 °C isotherms; diamonds are the measured temperatures. The column on the right shows the windows of the latest well.
