Commitments [Abstract]
Commitments	Note R – Commitments The Company leases production and other facilities under operating leases. The most significant operating leases are associated with floating, production, storage and offloading facilities at the Kikeh oil field, the West Patricia field and the Gulf of Mexico Cascade Chinook facility. During each of the next five years, expected future net rental payments under all operating leases are approximately $188.6 million in 2019, $88.9 million in 2020, $61.9 million in 2021, $27.6 million in 2022 and $15.6 million in 2023. Rental expense for noncancelable operating leases, including contingent payments when applicable, was $75.3 million in 2018, $72.6 million in 2017, and $77.5 million in 2016. A lease of production equipment at the Kakap field offshore Sabah, Malaysia has been accounted for as a capital lease and is included in long-term debt discussed in Note H. The Company has entered into contracts to hire various drilling rigs and associated equipment for periods beyond December 31, 2018. These rigs will primarily be utilized for drilling operations in onshore U.S., Canada, and the Gulf of Mexico. Future commitments under these contracts, all of which expire by 2020, total $57.9 million. Gulf of Mexico rig contracts are short term in nature and can be terminated within 30 days without cost. A portion of these costs are expected to be borne by other working interest owners as partners of the Company when the wells are drilled. These drilling costs are generally expected to be accounted for as capital expenditures as incurred during the contract periods. Note R – Commitments (Contd.) The Company has operating, production handling and transportation service agreements for oil and/or natural gas operations in the U.S. and Western Canada.
