HotSpot Maps are designed to show the intensity of predicted drilling activity for the next six months, based on county or watershed. Permits -- indicating where a well is approved for drilling -- are matched to records showing when drilling actually began at the site, allowing us to calculate the average length of time from permit approval to drilling start. We continually collect new permit data to predict which areas are most likely to experience relatively high drilling activity.
Load Maps depict the density of permits issued, or wells drilled, by county or watershed. These maps can be used by watershed monitoring groups or citizens to focus their investigations on areas at highest risk from impacts related to oil and gas development.
