CHEYENNE, Wyo. (AP) — A major oil development company has acquired a 5,000-acre ranch southeast of Cheyenne that until recently belonged to U.S. Rep. Cynthia Lummis and her family.

Laramie County records show the Lummis family transferred the Lummis Ranch South Camp property to a limited liability company March 20. Six weeks later, Cheyenne-based Frontier Plains, LLC, transferred the ranch to Houston-based EOG Resources.

Public documents don't detail terms of either deal. But EOG is developing numerous oil wells in southeast Wyoming, including at least four oil wells on the former Lummis property.

Lummis is saying little about the initial transaction involving her family except that it involved a land exchange. Frontier Plains and EOG officials didn't respond to requests for comment.

A real estate broker had listed the Lummis property for $8.1 million.
