worth a read, page-4

Technology has increased the success rate of finding commercial oil or gas deposits.

1) In the United States, for example, dry holes still accounted for 12% of all wells drilled in 2006.

2) For wells seeking new deposits of oil or gas, or exploratory wells, technology has decreased the dry hole rate from 78% (only 22% of wells finding commercial quantities of oil or natural gas) in 1973 to 49% in 2006.

Great post M8, just got a bit confused, because info from 1 & 2, seem to not compliment each other.

1) says 88% holes not Dry

2) says 51% holes not Dry


But its 3:30am, so chances are I am not thinking straight.
