text: **c) Development and Production Assets and Property and Equipment**
  Development and production assets, and property and equipment are carried at cost less, where applicable, any 
  accumulated depreciation, amortisation and impairment losses. The costs of assets constructed within the Group 
  includes the cost of materials, direct labor, borrowing costs and an appropriate proportion of fixed and variable 
  overheads directly attributable to the acquisition or development of oil and gas properties and facilities necessary 
  for the extraction of resources. 
  
  The carrying amount of development and production assets and property and equipment are reviewed at each 
  reporting date to ensure that they are not in excess of the recoverable amount from these assets. Development and 
  production assets are assessed for impairment on a cash-generating unit basis. A cash-generating unit is the smallest 
  grouping of assets that generates independent cash inflows. Management has assessed its CGUs as being an 
  individual basin, which is the lowest level for which cash inflows are largely independent of those of other assets. 
  Impairment losses recongised in respect of cash-generating units are allocated to reduce the carrying amount of the 
  assets in the unit on a pro-rata basis.
