Part of the Oil and Gas Investment Calculator. Start there for the wide view, then come back here for the close-up.

An oil and gas investment opportunity bases its program on oil price forecasts and economic predictions to calculate ROI. Investors need a comparison to choose the best option.
When oil prices drop, such as the $20/bbl drop in annual Brent averages between 2019 and 2020, the expected payback date disappeared. To reveal realistic financial risk, an oil price stress test evaluates holding the same well at fixed prices of $60/bbl, $75/bbl, and a baseline spot price (for example, $91.85/bbl) over its entire production life to determine possibilities for these ROI scenarios.

What if oil drops?

These baseline assumptions show a standard horizontal well under the following parameters:

Prices as of Oct 10, 2026.

A larger stake changes the dollars returned, not the payback date, under these program terms.

Model assumptions

One well making 150 bbl/day from 100,000 recoverable bbl. Held steady: gas at $3.342/mcf, 100 mcf/day, 4,000,000 recoverable mcf, 12.5% landowner royalty, Texas severance (4.6% oil, 7.5% gas), and $2,500/month operating cost for the whole well. One unit is $400,000, a tenth of an example program; stakes run from $50,000 to $4,000,000. The full calculator defaults to its own operating cost and the program terms set there, which this card cannot send. Example arithmetic, not investment advice.

This oil price stress test is a simplified demo of the full calculator at revenue.pcdrama.com: two fixed prices, one price you can type, one investment, and four well-stage presets that set how fast production falls. The table below says what each row holds still and what it lets move, and the section after it reports what the four presets did to payback at $60 and $75 when I ran them.

Control What it holds for every month What it moves
Every barrel at $60 $60 oil for the whole projection, never a price that drifts The payback date and the total recovery in that row
Every barrel at $75 $75 oil for the whole projection The same two, in the second row
Starting price, or your price The price this page was built with, or the one you type The third row, and the chart when that row is selected
Investment $50,000 to $4,000,000, sold in eighths of a $400,000 unit Dollars returned only; the payback date stays where it was
Well stage One of four yearly decline rates, or the example's 15% How long the well produces, and whether it pays back at all

What the four well stages did to payback at $60 and $75

A new well pumps hardest in year one and slides fastest after it. In our runs that early decline, more than the oil price, decided whether the stake came back.

We ran the engine behind this card at every well-stage preset and both fixed prices on October 16, 2026, and the result that surprised me was that the oil price did not decide whether the well pays back. The decline did. At the New shale preset, 65% a year, the example stake never recovers at $60 or at $75: production stops the month its revenue no longer covers its share of the operating cost, at month 52 for $60 and month 54 for $75, and the cumulative cash line flattens out under the investment line without crossing it. At the other three presets, and at the example program's 15%, both prices pay back, and the well runs until its 100,000 barrels are gone. At 17% a year or gentler, the gas keeps it producing for years after the last barrel.

On the example $400,000 stake, the four stages that pay back do it in 18.4 to 24.3 months at $60 oil and in 14.5 to 17.9 months at $75. New shale never gets there: $252,470 comes back at $60 and $317,191 at $75, and the well shuts in before the stake comes back.

Method: fifteen runs of the engine ported from the full calculator, five decline rates times three prices, with every other default held: 150 barrels of oil and 100 Mcf of gas a day, 100,000 barrels of recoverable reserves, a 12.5% landowner royalty, Texas severance tax and $2,500 a month of operating cost for the whole well. The runs are committed as the fixture file the card's own tests check against, so this page and the card read from one copy of the arithmetic. To repeat a row, press a stage button on the card and read that row's "Paid back by" line; "Not within the life of the well" is the line that mattered.

Well stage Yearly decline Payback at $60 Payback at $75 Total recovery on $400,000 Production ends
New shale, first year 65% Never Never $252,470 at $60, $317,191 at $75 Month 52 at $60, month 54 at $75, at the economic limit
Young shale, years 2 to 4 30% 24.3 months 17.9 months $505,269 at $60, $630,482 at $75 Month 36, when the reserves run out
Settled shale, year 5 on 17% 20.1 months 15.6 months $509,488 at $60, $634,701 at $75 Oil out at month 27, gas runs to month 57
Conventional, vertical and mature 8% 18.4 months 14.5 months $520,167 at $60, $645,379 at $75 Oil out at month 24, gas runs to month 127
Example program, no preset pressed 15% 19.6 months 15.3 months $510,790 at $60, $636,002 at $75 Oil out at month 26, gas runs to month 65

We measured this on our own calculator: a steeper first year can take a well from paying back at both prices to paying back at neither, before the oil price has moved at all.

Why Unrecovered Wells Still Send Checks

Link to section: Why Unrecovered Wells Still Send Checks

As long as net monthly revenue exceeds operating costs, regular revenue checks will continue to pay out, though each check becomes progressively smaller.

Production stops under one of two conditions:

  • Reserve Depletion: The well has produced all 100,000 recoverable barrels. Gas can keep it producing after the oil is done.
  • Economic Limit: Net monthly cash flow hits zero or drops negative (revenue no longer covers operating cost), at which point the model shuts the well in.

For steep first-year drops (65%), the economic limit occurs while recoverable barrels are still in the ground.

Total recovery on the card is cumulative net cash received, including getting the investment back, which is why a row can read as recovered and still be a poor return, or read as never recovered while having sent most of the money home. The chart draws the selected row's cumulative cash from $0 against a dashed line at the investment, and the payout marker only appears where the curve crosses it. On a New shale row at $60 the curve flattens underneath the line and the caption says the investment is not recovered, which is the picture the pitch deck never includes.

Shale Oil Decline Rates Behind the Presets

A gauge with its needle low. The four presets stand in for the one reading every projection leans on: how fast this well is giving out.

The four decline presets are derived from published research by the Journal of Petroleum Technology (JPT) and the International Energy Agency (IEA):

  • New Shale (65%): Reflects Permian Basin horizontal wells losing 65% to 85% of output in their first year.
  • Young Shale (30%): Reflects typical year-two decline across tight oil plays.
  • Settled Shale (17%): Represents year-five averages for Permian and Bakken horizontal wells.
  • Conventional (8%): Corresponds to post-peak averages across global conventional fields.

"The most recent production data reveal that tight oil wells are not living up to this standard."

Trent Jacobs writing for the Society of Petroleum Engineers' Journal of Petroleum Technology, in Life After 5: How Tight Oil Wells Grow Old (January 2020)

Testing the initial first-year decline button is critical, as a well in its first year is what most programs are actively selling.

Which decline rate fits which well, and who measured it?
Preset Yearly decline Fits Source
New shale 65% A horizontal shale well in its first year of production JPT: over 50% in year one across the main plays; IHS via JPT: 65% to 85% for the newest Permian wells
Young shale 30% The same well in years two to four JPT, "Life after 5": about 30% in year two
Settled shale 17% A shale well five or more years old JPT, "Life after 5": Permian and Bakken average about 17% at year five, Eagle Ford 23.5%
Conventional 8% A vertical well in a mature field IEA 2025: 5.6% a year post-peak across about 15,000 conventional oil fields, over 11.6% for small ones
No preset 15% The example program's own assumption The full calculator's default, kept so the hub and this page agree
  • Stake Scalability: Doubling the investment stake doubles total dollars returned but leaves the payback date unchanged, because revenue and operating expenses scale proportionally with each unit.
  • Impact of Price on Well Life: Lower oil prices shorten well lifespan only when steep decline rates bring forward the economic limit before reserves are depleted.
Link to section: What the link to the full calculator carries

"Open the full calculator" takes the row you selected with it: the investment after the program's $50,000 minimum and $4,000,000 cap are applied, the selected row's oil price, the active decline, and the page's gas price, gas rate, reserves, royalty and severance rates. What it cannot carry is the operating cost, because the full calculator reads that from its own program terms, and the two can differ. The example on this page charges the whole well $2,500 a month; the full calculator uses whatever its program settings say. The line under the link says so, and the month-by-month table you will find there is the place to check how far the two drift.

If the row you want to argue about is the one that never pays back, type a price into the third row instead of guessing: the chart redraws for your price, the link rebuilds from it, and the question for the sponsor writes itself. The oil and gas investment calculator this page hangs off covers the other three numbers that decide a well, the production rate, the reserves and who gets paid before you, plus the tax rules the 2022 version of that page got wrong.

Does a lower oil price shorten how long the well produces?

Only when the decline is steep enough for the economic limit to arrive before the reserves do. In my runs, at 65% a year the well shut in at month 52 at $60 and month 54 at $75; at every other preset the 100,000 barrels ran out first and the price changed nothing about the well's life.

Why does a bigger investment not change the payback date?

Each unit buys an equal share of the revenue and an equal share of the operating cost, so the cash flow scales with the stake and the month it crosses the investment line does not move. The dollars returned scale with it.

Is $60 a forecast?

No. It is a fixed scenario held for every month, chosen because it sits under the $65 average that energy executives told the Dallas Fed in March 2025 they need to drill a new well profitably. A price path that drops in year two is a different model and this card does not run one.

What does "Not within the life of the well" mean?

The cumulative net cash flow never reaches the investment before production stops, at the reserve estimate or at the economic limit. The row still shows the total recovery, which is the money that did come back.

The decline figures come from the Society of Petroleum Engineers' journal and the International Energy Agency, and the break-even context from the Federal Reserve Bank of Dallas, which surveys energy executives every quarter.

This stress test is for illustration only. Its results are not investment, tax or legal advice and do not promise any rate of return or cash flow, so talk to a CPA familiar with oil and gas before you invest.
