Hidden Hurdles Can Trip Prospects

Business Side of Geology

OK — as Prospector, you think you've finished your job:

After first identifying the anomaly and delineating its basic attributes, you've now completed the requisite geotechnical work refining that promising new prospect.

In concert with your engineering colleagues, you've developed responsible estimates for prospect reserves, chance of completion, initial production rates, per-well recoveries, production schedules and costs for drilling, completions, facilities and operations. You've gathered necessary data on contract terms and tax impacts.

Now it's time to integrate all this information (together with other assumptions and parameters) into a cash-flow model for the success-case outcome of the venture. This will be a discounted cash flow (DCF) analysis expressing a responsible value for the project, as Net Present Value (NPV), the fundamental economic measure.

The chance-weighted NPV and projected cash-flow profile will be compared against counterpart data from other projects, in choosing which projects (and in what share) will be drilled as part of the company's annual E&P portfolio.

But now's the time for you, the Prospector, to be on the lookout for "Hidden Hurdles."


"Hidden Hurdles" is a term I proposed about 15 years ago for arbitrary economic requirements that are inserted into the project evaluation process, ostensibly to help screen out less worthy projects.

"Hidden Hurdles" are:

  • Commonly employed by well-meaning business people who see their task as guardians protecting the firm against irresponsible explorationists, even though they themselves are not actually accountable for exploration performance.
  • Insidious, because their existence is generally not apparent to prospect-generators.
  • Dangerous, because — ironically — they often have impacts on project evaluations that are different from what was intended. Usually, they select against growth projects — and successful exploration is mostly about creating growth.

Here are some examples of "Hidden Hurdles":

 Arbitrarily elevated discount rates.

The discount rate selected for the project cash-flow model expresses the time-value of future production revenues and net cash flows. It is not a useful proxy for countering perceived risk. Excluding projects independently financed from foreign banking sources, the same discount rate should apply to all E&P projects in the corporate portfolio — after all, it's all the same money!

The discount rate should express the corporation's average weighted cost-of-capital, which is ordinarily about the same as prevailing corporate loan rates, or a little higher. Presently, that should be around 8 percent. Elevated discount rates preferentially penalize longer-term cash flows, so large-scale projects are undervalued relative to short-term projects.

 Arbitrarily depressed oil-price forecasts.

For E&P projects whose production revenues don't begin until three-to-six years after project initiation, use the mean historical oil price corrected for inflation to production - onset year one, adjusted for regional market effects and inflated by a realistic inflation factor. Using much lower projected prices — as a putative "safety factor" — may allow you to sense how sensitive the project may be to sustained downward price shifts, but causes the DCF analysis to lose its value as an objective predictor of project profitability.

Never forget that crude oil behaves as an (imperfect) commodity, and has done so since 1985. Prices will fluctuate throughout field life, so the mean is the preferred predictive price.

 Overly pessimistic drilling-cost estimates.

The psychology of completing a drilling project under AFE cost is a lot more pleasant than an AFE over-run. Consequently, there is often a tendency for drilling costs to be overly pessimistic, resulting in much higher front end costs that hammer otherwise worthy projects.

Challenge your drilling experts — remember that Unocal's drillers made their exploration colleagues look very successful in the Gulf of Thailand!

 Excessive minimum economic field-size requirements.

In new play projects where several discoveries may reasonably be contemplated given venture success, don't insist on recovering all investments from just one big field. Instead, consider that two or three middle-sized discoveries may in fact be a more plausible outcome than one very large discovery. Let lognormality work for you!

 Secret minimum prospect-reserves requirements.

Although everyone accepts the need for corporate efficiency, the notion of a "headquarters prospect minimum" is often counterproductive, because:

  • Such a "Hidden Hurdle" may be demoralizing to prospectors.
  • It presupposes far more precision in estimating reserves than the facts show.
  • It ignores what should be our primary goal: adding value, not just reserves.
  • It prevents consideration of such ventures from the portfolio point of view.
  • It disallows the efficient monetization of projects not selected for the portfolio, through farmout or sale.

So, as a conscientious professional prospector, watch out for those "Hidden Hurdles" — they can incorrectly trip-up your prospect!


This month's reading recommendation: "The Lexus and the Olive Tree: Understanding Globalization" by Thomas L. Friedman (2000 Anchor Books). An excellent world overview of the inherent conflict between the evolution of global business and the preservation of different cultures; superb insight on the Middle East.
