SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
Oil and gas assets (continued)
Commercial reserves
Proven and probable oil and gas reserves as defined in the Petroleum Resources Management System (“PRMS”)
are considered as commercial reserves.
Proven reserves include reserves that are confirmed with a high degree of certainty through an analysis of the
development history and a volume method analysis of the relevant geological and engineering data. Proven
reserves are those that, based on the available evidence and taking into account technical and economic factors,
have a better than 90% chance of being produced.
Probable reserves are those reserves in which hydrocarbons have been located within the geological structure with
a lesser degree of certainty because fewer wells have been drilled and certain operational tests have not been
conducted. Probable reserves are those reserves that, on the available evidence and taking into account technical
and economic factors, have a better than 50% chance of being produced.
These reserves are being calculated under existing economic and operating conditions, i.e., prices and costs as at
the date the estimate is made. Prices include consideration of changes in existing prices provided by contractual
arrangements and management’s forecast of future prices.
These estimates, made by the Group’s engineers and periodically evaluated by independent reservoir engineers,
are reviewed annually and revised, either upward or downward, as warranted by additional data. Revisions are
necessary due to changes in, among other things, reservoir performance, prices, economic conditions and
governmental restrictions.
Other fixed assets
Other fixed assets are stated at cost less accumulated depreciation and any accumulated impairment losses. Cost
includes the purchase price and directly associated costs of bringing the asset to a working condition for its
intended use. Depreciation is calculated based on the estimated useful lives of the applicable assets on a straight-
line basis, on the following basis:
Office equipment 5 years
Motor vehicles 5 years
Fixtures and fittings 10 years
The estimated useful lives, residual values and depreciation method are reviewed at each year end, with the effect
of any changes in estimate accounted for on a prospective basis.
Maintenance and repairs, replacements and improvements of minor importance are expensed as incurred.
Significant improvements and replacement of assets are capitalised.
The gain or loss arising on the disposal or retirement of other fixed assets is determined as the difference between
the sales proceeds and the carrying amount of the asset and is recognised in the consolidated statement of income.
Impairment of tangible assets
At each balance sheet date, the Group reviews the carrying amounts of its tangible assets to determine whether
there is any indication that those assets have suffered an impairment loss. If any such indication exists, the
recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if any).
