As of December 31, 2012, SandRidge had drilled and perforated for completion approximately 454 equivalent Trust Development Wells (10K/Annual Report 3/15/13), leaving 434 remaining to be drilled from the original commitment of 888 wells.
Only thing getting 'drilled' here is the investor. Not a very good chart. As far as wells go, you have to believe they've drilled the most favorable wells first.At least that would be what would make the most sense. So, from here I'd not be too enthusiastic.
