text: **Exploration and Evaluation**
  The Company’s policy for exploration and evaluation is discussed in Note 1 (b). The application of this policy requires 
  the Company to make certain estimates and assumptions as to future events and circumstances, particularly in 
  relation to the assessment of whether economic quantities of reserves have been found. Any such estimates and 
  assumptions may change as new information becomes available. If, after having capitalised exploration and 
  evaluation expenditure, management concludes that the capitalised expenditure is unlikely to be recovered by 
  future sale or exploitation, then the relevant capitalised amount will be written off through the consolidated 
  statement of profit or loss and other comprehensive income. 
  
  **Restoration Provision**
  A provision for rehabilitation and restoration is provided by the Group to meet all future obligations for the 
  restoration and rehabilitation of oil and gas producing areas when oil and gas reserves are exhausted and the oil and 
  gas fields are abandoned. Restoration liabilities are discounted to present value and capitalised as a component part 
  of capitalised development expenditure. The capitalised costs are amortised over the units of production and the 
  provision is revised at each balance sheet date through the consolidated statement of profit or loss and other 
  comprehensive income as the discounting of the liability unwinds. 
  
  In most instances, the removal of the assets associated with these oil and gas producing areas will occur many years 
  in the future. The estimate of future removal costs therefore requires management to make significant judgements 
  regarding removal date or well lives, the extent of restoration activities required, discount and inflation rates.
