Could they buy them, yes, but seems unlikely based on the limited information available. Is Yates production heavily PDP? This seems like the kind of deal where a large major can pick up acreage and production and pay a premium to gain a foothold or strengthen their holdings in the area.
As fae as I can determne, it's all PDP exept for the tiny Bakken acreage, which they are only part owner. Linn has operations in the Powder River Basin and could use the Yates Pipelines there. It would expand Linn's New Mexico operations.
