The difference between the actual results and estimates are recognized in the period in which the results are known or materialized.

d.2 Intangible Assets

Intangible assets are stated at cost of acquisition, net of applicable tax credits, less accumulated amortization and impairment.

e. Exploration, Development and Production Costs

e.1 Pre-acquisition cost

Expenditure incurred before obtaining the right(s) to explore, develop and produce oil and gas are expensed as and when incurred.

e.2 Acquisition Cost

Acquisition costs of an oil and gas property are costs related to right to acquire mineral interest and are accounted/ treated as follows:-Exploration and Development stage: Acquisition cost relating to projects under exploration or developments are initially accounted as capital work in progress. Such costs are capitalized by transferring to Producing Property when a well is ready to commence commercial production. In case of abandonment/ relinquishment, such costs are written off.

Production stage:

Acquisition costs of a producing oil and gas property are capitalized as proved property acquisition cost under producing properties and amortized over the production profile of the underlying asset using the unit of production method over proved reserves.

e.3 Survey Cost

Cost of Survey and prospecting activities conducted in the search of oil and gas are expensed as exploration cost in the year in which these are incurred.

e.4 Exploratory/ Development Wells in Progress e.4.1 All exploration costs incurred in drilling and equipping exploratory and appraisal wells, cost of drilling exploratory type stratigraphic test wells are initially capitalized as Exploratory ells in Progress till the time these are either transferred to Producing Properties on completion as per note no.2. f.1.1 or expensed as exploration cost (including allocated debrciation) as and when determined to be dry or of no further use, as the case may be.

e.4.2 Costs of exploratory wells are not carried unless there are indications of sufficient quantity of reserves and sufficient progress is being made in assessing the reserves and the economic and operating viability of the project. All such carried costs are subject to review for impairment as per note no. 2.n.7.

e.4.3 All costs relating to Development Wells are initially capitalized as 'Development ells in Progress' and transferred to 'Producing Properties' on "completion" as per note no. 2.f.

f. Producing Properties

f.1.1 Producing Properties are created in respect of an area/field having proved developed oil and gas reserves, when the well in the area/field is ready to commence commercial production.

f.1.2 Cost of temporary occupation of land, successful exploratory wells, all development wells, debrciation on related equipment, facilities and estimated future abandonment costs are capitalised and reflected as Producing Properties.

g. Production Costs

Production costs include br-well head and post-well head expenses including debrciation and applicable operating costs of support equipment and facilities.

h.2 In case of development wells, the entire cost of abandoned portion and side tracking is capitalised.

h.3 In case of Producing wells, if the side-tracking results in additional proved developed oil and gas reserves or increases the future economic benefits therefrom beyond brviously assessed standard of performance, the cost incurred on side tracking is capitalised, whereas the cost of abandoned portion of the well is depleted in the normal way. Otherwise, the cost of side tracking is expensed as Work over Expenditure'

i. Abandonment Cost

1.1 The full eventual estimated liability towards costs relating to dismantling, abandoning and restoring well sites and allied facilities are recognized in respective assets when the well is complete / facilities are installed. The abandonment cost on dry well is expensed as exploratory well cost.

n.5 Depletion

Producing Properties are depleted using the "Unit of Production Method". The rate of depletion is computed with reference to an area covered by individual lease/license/asset/ amortization base by considering the proved developed reserves and related capital costs incurred including  Properties is depleted by considering the proved reserves. These reserves are estimated annually by the Reserve Estimates Committee of the Company, which follows the International Reservoir Engineering Procedures.

Amortisation n.6 Leasehold land is amortized over the lease period except perpetual leases.

Intangible assets are amortized on Straight Line Method (SLM) over the useful life not exceeding five years from the date of capitalization.

Impairment

n.7 Producing Properties, Development Wells Progress (DWIP), and Fixed Assets (includinCapital Works in Progress) of a "Cash Generatin

Unit" (CGU) are reviewed for impairment at each Balance Sheet date. In case, events and circumstances indicate any impairment, recoverable amount of these assets is determined. An impairment loss is recognized, whenever the carrying amount of such assets exceeds the recoverable amount. The recoverable amount is higher of its 'value in use' or 'net selling price' (if determinable). In assessing value in use, the estimated future cash flows from the use of assets and from its disposal at the end of its useful life are discounted to their brsent value at appropriate rate.

An impairment loss is reversed if there is increase in the recoverable amount and such loss either no longer exists or has decreased. Impairment loss / reversal thereof is adjusted to the carrying value of the respective assets, which in case of CGU, is allocated to its assets on a pro-rata basis. Subsequent to impairment, debrciation is provided on the revised carrying value of the assets over the remaining useful life. Impairment testing during exploratory phase is carried out at area level when further exploration activities are not planned in near future or when sufficient data exists to indicate that although a development in the specific area is likely to proceed, the carrying amount of the exploration asset is unlikely to be recovered in full from successful development or by sale. Impairment is reversed subsequently, to the extent that conditions for impairment are no longer brsent.
