Related Party Transactions [Abstract]
Related Party Transaction Text Block		Related-Party Transactions: Kevin M. Robinson, our former Vice President — Asia through February 10, 2014, and Susan G. Riggs, our current Treasurer, were minority owners of Huffco International L.L.C. (Huffco). In May 1997, before Mr. Robinson and Ms. Riggs joined the Company, we acquired from Huffco an entity now known as Newfield China, LDC, the owner of a 12% interest in a three-field unit located in Bohai Bay, offshore China. Huffco retained preferred shares of Newfield China that provided for dividend payments. During the third quarter of 2013, we purchased the outstanding preferred shares of Newfield China from Huffco for approximately $20 million, which was recorded as a charge against retained earnings.
