9. Is there something about the geology of spots where companies like to drill that causes higher methane levels? 10. Were the wells sampled chosen for proximity to drill sites? Did the sampling methodology allow for the possibility that methane levels can spike without a nearby well? 11. Was there any relationship between levels and the length of time the well has been operating? Depth of well? I'd add that the SA headline isn't exactly a dispassionate summary of the article.
