Again we will use the data in the example above, but in this example we will have to add in the estimated costs of the 7 remaining development wells. Capitalised exploration and appraisal costs Capitalised development costs 7 further development wells Total proved reserves Proved developed reserves Production in period Required: $62,000,000 $874,000,000 $84,000,000 326,000,000 barrels 214,000,000 barrels 21,000,000 barrels Calculate DD&A charge for the accounting period using the prospective method. Assume the total number of wells to be drilled has not changed.
