Five Things to Weigh Before Investing in Oil and Gas

Big deductions, bigger risk — know the trade before the write-off.

Drilling investments carry some of the largest first-year deductions in the tax code. That generosity exists because the money is genuinely at risk: a well can come in strong, come in weak, or come in dry. Treat the deduction as a discount on a risky purchase, never as the reason to buy.

What to know

Intangible drilling costs
Labor, fuel, and site preparation — the part of a well with no salvage value — can often be deducted almost entirely in the first year.
Depletion
As reserves are pumped out, an allowance lets owners deduct part of the income the wells produce, similar in spirit to depreciation on a building.
Working interest versus royalty
A working interest brings active-business treatment and liability for costs; a royalty interest is passive income with far fewer deductions.
Who the sponsor is
Track record, geology, and fee structure decide the outcome. Read the offering documents and the operator's history of completed wells.
Liquidity is limited
There is rarely a market to sell your piece. Assume the money stays in until the wells run their life.

The tax benefit

A large share of the investment can be deducted in year one, and depletion shelters part of the income the wells produce afterward.

Worked example

A $100,000 drilling interest

Roughly $70,000 to $80,000 might be deductible in the first year as intangible drilling costs. If the wells produce, depletion then shelters part of each year's checks — but if they do not, the deduction is all the investor keeps.

Watch out for

  • A deduction is not a return; losing a dollar to save 35 cents is still losing 65 cents.
  • Working interests can carry environmental and cost liability, not just upside.
  • Aggressive promoters sell tax stories rather than geology — verify both.
