5. CRITICAL ACCOUNTING ESTIMATES AND JUDGMENTS
The preparation of financial statements in conformity with approved accounting standards requires
the use of certain accounting estimates. It also requires management to exercise judgement in the
process of applying the Group's accounting policies. Estimates and judgements are continually
evaluated and are based on historical experience, including expectation of future events that are
believed to be reasonable under the circumstances. The areas where various assumptions and
estimates are significant to the Group's financial statements or where judgment was exercised in
application of accounting policies are as follows:

i) Estimated crude oil/gas reserves used for amortization of development and
decommissioning costs - note 4.15 and 14
ii) Estimated useful life of property, plant and equipment - note 4.13 and 13.1
iii) Estimated costs, discount and inflation rate used for provision for decommissioning costs -
