So there is no danger of anything igniting?
Manageable danger. First, most well production is shut down on BLM land (our land, not BLM's... GRR) during stage 2 fire conditions (which has been the status for a while.) As well, well pads are usually kept clear of vegetation. This actually makes them staging areas for most firefighting work.
The biggest danger is using heavy equipment in the area breaking underground pipes that will have residual petroleum products in them.
Outside of well pads, there are condenser tanks and pumping stations - these have less clearance around them, and are more exposed for wildfires. That said, again, these places are generally cleared of all vegetation or at least any major fuel sources for a wild fire.
So, in summary, well pads are places where firefighters can make a stand against a wildfire. Better, though, is to let loggers in before the wildfire can happen and let them thin the forest, both for the health of the forest, and for the benefit of jobs.
