* At December 31, the standardized measure of discounted future net cash flows relating to proved reserves in Norway were as follows:
## Table 1 ##
HESS CORPORATION AND CONSOLIDATED SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – (Continued) 2012, assets totaling $1,092 million, including allocated goodwill of $100 million, and liabilities totaling $539 million that were related to the ACG and Beryl fields, which were divested in the first quarter of 2013, were reported as held for sale.
Properties classified as held for sale are not depreciated but are subject to impairment testing.
Capitalized Exploratory Wells Costs: The following table discloses the amount of capitalized exploratory well costs pending determination of proved reserves at December 31, and the changes therein during the respective years:
## Table 2 ##
In 2013, capitalized well costs reclassified based on the determination of proved reserves primarily related to the Shenzi project in the Gulf of Mexico.
Capitalized exploratory well costs charged to expense in 2013 in the preceding table include $260 million to write-off previously capitalized exploration wells in Area 54, offshore Libya, due to civil unrest.
The preceding table excludes exploratory dry hole costs of $77 million, $248 million and $348 million in 2013, 2012 and 2011, respectively, which were incurred and subsequently expensed in the same year.
At December 31, 2013, exploratory drilling costs capitalized in excess of one year past completion of drilling were incurred as follows (in millions):
## Table 3 ##
The capitalized well costs in excess of one year relate to 8 projects.
Approximately 45% relates to Block WA-390-P, offshore Western Australia, where development planning and commercial activities, including negotiations with potential liquefaction partners, are ongoing.
Successful negotiation with a third party liquefaction partner is necessary before the Corporation can negotiate a gas sales agreement and sanction development of the project.
Approximately 27% relates to the Corporation’s Pony discovery on Block 468 in the deepwater Gulf of Mexico, and 8% relates to the Pony #3 well on Block 469.
The Corporation has signed an exchange agreement with the partners of the adjacent Green Canyon Blocks 512 and 511, which contain the Knotty Head discovery.
Under this agreement, Hess was appointed operator and has a 20% working interest in the blocks, which are now collectively referred to as the Stampede project.
An application to unitize Blocks 468, 512, the western half of 469 and the eastern half of 511 is due to be filed with the Bureau of Safety and Environmental Enforcement in the first quarter of 2014.
Field development planning is progressing and the project is targeted for sanction in 2014.
Approximately 16% relates to offshore Ghana where the Corporation has drilled seven successful exploration wells.
Appraisal plans for the seven wells on the block were submitted to the Ghanaian government for approval in June 2013 and by year-end four had been approved.
The Corporation plans to commence a three well appraisal drilling program in the second half of 2014.
The remainder of the capitalized well costs in excess of one year relates to projects where further drilling is planned or development planning and other assessment activities are ongoing to determine the economic and operating viability of the projects.
the analysis of our depreciation studies.
Changes in the estimated service lives of our assets and their related depreciation rates are implemented prospectively.
Under group depreciation, the historical cost (net of salvage) of depreciable property that is retired or replaced in the ordinary course of business is charged to accumulated depreciation and no gain or loss is recognized.
The historical cost of certain track assets is estimated using (i) inflation indices published by the Bureau of Labor Statistics and (ii) the estimated useful lives of the assets as determined by our depreciation studies.
The indices were selected because they closely correlate with the major costs of the properties comprising the applicable track asset classes.
Because of the number of estimates inherent in the depreciation and retirement processes and because it is impossible to precisely estimate each of these variables until a group of property is completely retired, we continually monitor the estimated service lives of our assets and the accumulated depreciation associated with each asset class to ensure our depreciation rates are appropriate.
In addition, we determine if the recorded amount of accumulated depreciation is deficient (or in excess) of the amount indicated by our depreciation studies.
Any deficiency (or excess) is amortized as a component of depreciation expense over the remaining service lives of the applicable classes of assets.
For retirements of depreciable railroad properties that do not occur in the normal course of business, a gain or loss may be recognized if the retirement meets each of the following three conditions: (i) is unusual, (ii) is material in amount, and (iii) varies significantly from the retirement profile identified through our depreciation studies.
A gain or loss is recognized in other income when we sell land or dispose of assets that are not part of our railroad operations.
When we purchase an asset, we capitalize all costs necessary to make the asset ready for its intended use.
However, many of our assets are self-constructed.
A large portion of our capital expenditures is for replacement of existing track assets and other road properties, which is typically performed by our employees, and for track line expansion and other capacity projects.
Costs that are directly attributable to capital projects (including overhead costs) are capitalized.
Direct costs that are capitalized as part of selfconstructed assets include material, labor, and work equipment.
Indirect costs are capitalized if they clearly relate to the construction of the asset.
General and administrative expenditures are expensed as incurred.
Normal repairs and maintenance are also expensed as incurred, while costs incurred that extend the useful life of an asset, improve the safety of our operations or improve operating efficiency are capitalized.
These costs are allocated using appropriate statistical bases.
Total expense for repairs and maintenance incurred was $2.4 billion for 2014, $2.3 billion for 2013, and $2.1 billion for 2012.
Assets held under capital leases are recorded at the lower of the net present value of the minimum lease payments or the fair value of the leased asset at the inception of the lease.
Amortization expense is computed using the straight-line method over the shorter of the estimated useful lives of the assets or the period of the related lease.13.
