If the fracking / hydraulic fracturing were unsuccessful, you have no many options other than charging into expenses. You may initially recognize as an asset but then again at the end of the period you will have to test it for impairment because at the end of each reporting period, an entity is required to assess whether there is any indication that an asset may be impaired (i.e. its carrying amount may be higher than its recoverable amount). And because the jobs failed you will have to impair the total amount recognized.
