Exploratory Wells

Under FASB guidance, exploratory well costs should continue to be capitalized when the well has found a sufficient quantity of reserves to justify its completion as a producing well and the company is making sufficient progress assessing the reserves and the economic and operating viability of the project.

As of June 30, 2024, the Company had total capitalized drilling costs pending the determination of proved reserves of $43.0 million. The following table reflects the net changes in capitalized exploratory well costs during the six-month periods ended June 30, 2024 and 2023.

(Thousands of dollars)	2024		2023
Beginning balance at January 1	$	49,118	$	171,860
Additions pending the determination of proved reserves	20,391		47,733
Capitalized exploratory well costs charged to expense	(26,471)		(26,188)
Balance at June 30	$	43,038	$	193,405

Capitalized well costs charged to dry hole expense of $26.5 million for the six months ended June 30, 2024 was related to the Hoffe Park #1 (Mississippi Canyon 166) exploratory well in the Gulf of Mexico. Capital additions are mainly for Ocotillo #1 (Mississippi Canyon 40) exploratory well in the Gulf of Mexico. The preceding table excludes well costs of $31.8 million and $70.3 million incurred and expensed directly to dry hole for the six months ended June 30, 2024 and 2023, respectively. In 2024 the amount includes $25.5 million for the Orange #1 (Mississippi Canyon 216) exploration well in the Gulf of Mexico and in 2023 the amount includes $69.2 million related to the Chinook #7 exploration well in the Gulf of Mexico.

The following table provides an aging of capitalized exploratory well costs based on the date the drilling was completed for each individual well and the number of projects for which exploratory well costs have been capitalized. The projects are aged based on the last well drilled in the project.

	June 30,
	2024				2023
(Thousands of dollars)	Amount		No. of Wells	No. of Projects	Amount		No. of Wells	No. of Projects
Aging of capitalized well costs:
Zero to one year	$	20,545	3	3	$	8,494	1	1
One to two years	–		–	–	38,497		1	1
Two to three years	–		–	–	2,698		1	1
Three years or more	22,493		3	3	143,716		4	3
	$	43,038	6	6	$	193,405	7	6

Of the $22.5 million of exploratory well costs capitalized more than one year at June 30, 2024, $15.1 million was in Vietnam, $4.7 million was in Canada, and $2.7 million was in Brunei. In all geographical areas, either further appraisal or development drilling is planned and/or development studies/plans are in various stages of completion. 

Impairments

There were no impairments in the three months ended June 30, 2024. There were pre-tax impairments of $34.5 million in the six months ended June 30, 2024 related to Calliope field in Mississippi Canyon, in the Gulf of Mexico, where operational issues led to a reserve reduction. There were no impairments in the three and six months ended June 30, 2023.
