Zusammenfassung:	Methods and systems for controlling drilling operations are described. The methods include conveying a drilling tool from the earth surface into a wellbore and operating the drilling tool to drill in a drilling direction, wherein drilling mud is conveyed from the earth surface to the drilling tool and returned to the earth surface, obtaining gas data from the drilling mud that returns to the earth surface, determining a reservoir property from the gas data, and adjusting the drilling direction based on the determined reservoir property.
