Components of total lease cost [Table Text Block]

The following table reflects the components of the Company’s total costs, whether capitalized or expensed, related to operating leases, including short-term leases, and variable lease payments made for leases with initial lease terms greater than 12 months, for the years ended December 31, 2020, and 2019. This total does not reflect amounts that may be reimbursed by other third parties in the normal course of business, such as non-operating working interest owners.

	For the Years Ended December 31,
	2020		2019
	(in thousands)
Operating lease cost	$	17,980	$	35,570
Short-term lease cost (1)	143,892		301,373
Variable lease cost (2)	70,858		106,006
Total lease cost	$	232,730	$	442,949

____________________________________________

(1)    Costs associated with short-term lease agreements relate primarily to operational activities where underlying lease terms are less than one year. This amount includes drilling and completion activities and field equipment rentals, most of which are contracted for 12 months or less. It is expected that this amount will fluctuate primarily with the number of drilling rigs and completion crews the Company is operating under short-term agreements.

(2)    Variable lease payments include additional payments made that were not included in the initial measurement of the ROU asset and corresponding liability for lease agreements with terms longer than 12 months. Variable lease payments relate to the actual volumes transported under certain midstream agreements, actual usage associated with drilling rigs, completion crews, and vehicles, and variable utility costs associated with the Company’s leased office space. Fluctuations in variable lease payments are driven by actual volumes delivered and the number of drilling rigs and completion crews operating under long-term agreements.

ROU assets obtained in exchange for new operating lease liabilities totaled $745,000 and $25.4 million for the twelve months ended December 31, 2020, and 2019, respectively.

Cash paid for amounts included in the measurement of lease liabilities for the years ended December 31, 2020, and 2019, were as follows:
