Some costs incurred in an entity's oil- and gas- producing activities enter into the determination of taxable income and pretax accounting income in different periods. A principal example is intangible drilling and development costs, which are deductible in determining taxable income when incurred but which, for successful [exploratory wells](https://asc.understandingaccounting.org/glossary/e/#exploratory-well "An exploratory well is a well drilled to find a new field or to find a new reservoir in a field previously found to be productive of oil or gas in another reservoir. Generally, an exploratory well is any well that is not a development well, a service well , or a stratigraphic test well.") and for all [development wells](https://asc.understandingaccounting.org/glossary/d/#development-well "A development well is a well drilled within the proved area of an oil or gas reservoir to the depth of a stratigraphic horizon known to be productive."), are capitalized and amortized for financial accounting purposes under the provisions of this Topic. As another example, some geological and geophysical costs, which are charged to expense when incurred under the provisions of this Topic, are deferred and deducted in subsequent periods for income tax purposes.
