HOUSTON — Vanguard Natural Resources LLC said Monday it has closed its acquisition of oil and gas properties in Mississippi, Texas and New Mexico from an undisclosed private seller.

The purchase price was raised slightly to $114.6 million from $113.1 million when the deal was originally announced earlier this month.

Vanguard funded the acquisition through $71.5 million in net proceeds from its recent stock offering and borrowings under an existing credit facility.
