Capitalized exploration well-drilling costs: Suspended well costs

Exploratory drilling costs are capitalized until the drilling of the well is complete. If hydrocarbons are found, and, subject to further appraisal activity which may include the drilling of further wells, are likely to be capable of commercial development, the costs continue to be carried under construction in progress. All such carried costs are subject to technical, commercial and management review at least once a year to confirm the continued intent to develop or otherwise extract value from the discovery. When this is no longer the case, the costs are written off. If proved reserves of oil or natural gas are determined and development is sanctioned, the relevant expenditure is transferred to machinery and technical equipment. Unsuccessful exploration wells are impaired in exploration expenses.

The following table indicates the changes to the company’s capitalized exploration well-drilling costs.
