In BP's case these policies include less drilling, cap and trade, alternative energy.
While the technology required to drill — and cap — an oil well in deep water can be mind-boggling, cleaning up the spill required mostly tedious manual labor.
Then a Danish scientist published a paper about borings from the Greenland ice cap; the deep cylinders of ice, which had been drilled from the cap, enabled scientists to track CO2 trapped in the ice and determine a precise chronology of periods of heating and cooling.
During 2012, carrot seed was carefully hand-sown from a half-pint bottle with a small 1/8" hole drilled in the cap so that the seeds no closer than 1" from each other.
To bring the hydrocarbons to the surface, a well must be drilled through the cap rock and into the reservoir.
Two smaller holes were drilled through the cap for the thermocouple wires to pass through.
A 4.5 mm hole was drilled through the cap for the laser to pass through (the beam diameter was 4.4 mm).
Before gluing on the pipe end cap, drill a hole in the center of the cap just big enough for the bike valve.
And, as I write, archaeological scientists are carefully examining samples drilled from the ice cap of Greenland to find the traces, even there, of the pollution produced by Roman industry – the mines in Roman Spain, for example, where thousands of people, children included, worked in appalling industrial conditions to produce the silver that ended up as Roman small change.
If available, it's wise to seal the drilled hole on the cap with hot glue.
