Title 26 › Subtitle Subtitle A— Income Taxes › Chapter 1— NORMAL TAXES AND SURTAXES › Subchapter B— Computation of Taxable Income › Part VI— ITEMIZED DEDUCTIONS FOR INDIVIDUALS AND CORPORATIONS › § 193
You can deduct the costs you paid in a tax year for certain materials injected into oil wells to get more oil out, as long as those materials were actually injected during that year. "Qualified tertiary injectant expenses" — costs for tertiary injectants, except recoverable hydrocarbon injectants. "Hydrocarbon injectant" — natural gas, crude oil, or an injectant made mostly of those; a hydrocarbon-based injectant with only a tiny amount of gas or oil is not treated as a hydrocarbon, and non-hydrocarbon parts of a mix do not count as hydrocarbons. "Tertiary recovery method" — the methods listed in rule 212.78(c) of the June 1979 energy regulations, or other methods the Secretary approves. You cannot take this deduction for costs you elected to capitalize under section 263(c) or for costs already deductible under another tax rule.
