The challenging is getting the gas from a remote well location to a plant where it can be processed. This requires pipelines, gas gathering facilities, etc. If any of that infrastructure is experiencing an upset condition, the operator has to choose between shutting in the well or flaring the gas. Shutting in the well can be undesirable because it's still producing oil to tanks, and oil is where most of the profit is from. A shut-down well can also be hard to get going again.
