Big Popi Oil drilled an exploratory well in 2017 that was still in progress at year-end.Total costs incurred in 2017 were $1,000,000.During January 2018, drilling was completed and additional costs of $500,000 were incurred. Total depth was reached at the end of January, and it was determined in February that the well was dry and had not discovered proved reserves.

Assuming Big Popi uses the successful efforts method of accounting, and that Popi's financial statements are not issued until March 2018, what costs, if any, should be expensed for 2017 and / or 2018?
