Exploratory Well and Project Costs

Exploratory Well and Project Costs

The Company capitalizes exploratory well and project costs until a determination is made that the well or project has either found proved reserves, is impaired or is sold. The Company's capitalized exploratory well and project costs are included in proved properties in the consolidated balance sheets. If the exploratory well or project is determined to be impaired, the impaired costs are recorded in exploration and abandonments expense in the consolidated statements of operations.

The changes in capitalized exploratory well and project costs are as follows:

Additions to exploratory well and project costs pending the determination of proved reserves	3,047
Reclassifications due to determination of proved reserves	(2,678)
Ending capitalized exploratory well and project costs	$	1,203

Aging of capitalized exploratory costs and the number of projects for which exploratory well costs have been capitalized based on the date drilling was completed, are as follows:
