How do geologists decide where to drill for oil and gas?

Geologists use various methods, such as seismic surveys, gravity and magnetic surveys, and well data analysis to identify potential oil and gas reservoirs below the Earth's surface. Based on these data, they create detailed maps and models to pinpoint the most promising locations for drilling. Factors such as geologic structures, rock properties, and historical drilling success in the area are considered when deciding where to drill for oil and gas.
