What are your interests? Is your degree equivalent to a degree in geology? One field is environmental consulting. It does not pay as well as oil and gas, but you don't have to live near the oil and gas fields.
Do you want to work in the field, in an office, or both?
With a degree in earth science, oil and gas is a great spot to start. There are many differences with places to go based on your specific major/interests. Mud engineers, rig site geologists, field engineers, etc. are all possible.
