Michael, William JH is correct-3d mapping makes prospects more easily identifiable. Also better downhole bit control. Steel is very flexible and when drilling a well the drill string will slide right on harder formations, or even corkscrew if you do not control the bit well. Technology has allowed drillers to control the drill bit and its locations much better than say 20 years ago in 1979. Also horizontal well drilling technology is made possible by 3d seismic. Could not have (successfully) drilled a horizontal well in 1979-i.e, stayed in the target formation.... Offshore satellite data allows dynamically positioned drillships to maintain position better- and also to spud in the drill bit within three meters of the designated drilling location- no small feat in the middle of a big ocean on a rolling drillship...... Drilling technology today is accelerating in its improvements... Sincerely, Doug F.
