Study on economic evaluation methods and influencing parameters of new well projects in overseas developed oil fields
Chinese oil and gas companies mainly adopt the direct incremental evaluation method when conducting economic evaluation of newly drilled wells in developed oil and gas fields in China.Due to many factors,the direct incremental method cannot simply be applied to the economic evaluation of new wells drilled in overseas developed oil and gas fields.There are obvious differences between domestic and overseas developed oil and gas fields in terms of contract mode,financial and tax system,development and production period,and abandonment fee.For the economic evaluation of new drilling wells in overseas developed oil and gas fields,it is necessary to take into account the country-specific differences in the contract model and tax system,the selection of the evaluation period,the estimation of the investment cost,the disposal operation and the treatment of the disposal fee as the key influencing factors,and to evaluate the economy of the new drilling project using the"with or without comparison method".The evaluation period should be based on the shorter between contract term and the economic life of the oilfield.The treatment of investment costs should follow the principle of"relevance".The time value of deferred field abandonment payments for new drilled wells varies according to the resource country and contract terms.
