Conventional vs. Unconventional Wells: What Investors Should Know

Conventional vs. Unconventional Wells: What Investors Should Know

Not all oil and gas wells are the same. The difference between conventional and unconventional wells affects everything an investor cares about: cost per well, production decline rates, time to payout, and risk profile. Understanding the distinction helps you evaluate what you are actually investing in.

Conventional Wells

A conventional well targets a reservoir where oil and gas are trapped in porous rock (like sandstone or limestone) beneath an impermeable cap. The hydrocarbons flow naturally due to reservoir pressure. These wells are typically vertical, drilled to depths of 3,000-8,000 feet depending on the formation. In Oklahoma's Mid-Continent, common conventional targets include the Hunton Limestone, the Wilcox Sandstone, and the Misener Sandstone.

Conventional wells cost less to drill and complete. A vertical well in the Mid-Continent runs $400,000-$900,000 depending on depth and target zone. Decline curves are gentler: a good conventional well may decline 20-30% in year one, then flatten to 8-12% annual decline in subsequent years. Many conventional wells produce for 20-30 years.

Unconventional Wells

Unconventional wells target oil and gas locked in tight rock formations like shale. The hydrocarbons do not flow freely. They must be released through hydraulic fracturing (fracking) combined with horizontal drilling. A single horizontal well in the Permian Basin can extend 10,000+ feet laterally through the target formation.

The cost difference is dramatic. A horizontal shale well runs $6-$12 million to drill and complete. Initial production rates can be high, sometimes 1,000+ barrels per day, but decline curves are steep: 60-70% decline in the first year is common. Most of the well's lifetime production comes in the first 3-4 years. The economics depend on high initial rates and favorable oil prices to recover the large upfront capital.

Why It Matters for Your Investment

For direct participation investors, the well type determines your capital exposure and cash flow timeline. With conventional wells, your capital at risk per well is lower, decline rates are more gradual, and the production tail is longer. You get a steadier, longer-duration revenue stream. With unconventional wells, the upfront cost is much higher, the cash flow is front-loaded, and you need strong commodity prices to hit your return targets.

Where BassEXP Operates

BassEXP drills conventional vertical wells in Oklahoma's Mid-Continent region. We target proven formations with decades of production history. Our well costs are a fraction of what shale operators spend, which means less capital at risk and breakeven prices in the $35-$45/bbl range. We believe conventional wells in the right formations offer the best risk-adjusted returns for working interest investors.
