marathon acquisitions

I was reading back through some industry updates and came across this little gem:

After making a substantial investment in the South Texas Eagle Ford resource play in 2011, Marathon Oil has acquired or reached agreements in principle to acquire almost 25,000 additional net acres in the core of the play at an approximate cost of $1 billion so far in 2012. The two major transactions were the acquisition of Paloma Partners II LLC, whereby the Company acquired over 17,100 net acres at a cost of $750 million, and a pending acquisition of approximately 4,300 net acres for a currently estimated $227 million, both excluding purchase price adjustments. The Paloma acquisition closed in August, while the pending transaction is expected to close in the fourth quarter 2012. The acreage in the pending acquisition overlaps Marathon Oil operated acreage, is currently producing 2,900 net barrels of oil equivalent per day (BOED) and will add 40 net drilling locations to Marathon Oil's inventory.

1 = $43.9k/ac
2 = $52.8k/ac

Be interesting to know how much the vendor has spent on drilling to date.
