Haynesville Shale Mineral Rights

The Haynesville is a bet on natural gas demand, particularly LNG exports, and that demand story is a real input behind its calculator range.

The Haynesville Shale runs across East Texas and northwest Louisiana, one of the deepest and most prolific dry gas shale plays in the country. Wells here are expensive to drill — often reaching depths beyond 10,000 feet with high bottom-hole pressures and temperatures — but they can also produce very strong initial rates, and the play has seen renewed operator interest tied directly to the growth of U.S. LNG export capacity along the Gulf Coast.

For a value calculator, that LNG connection matters. Haynesville gas increasingly competes for pipeline capacity headed toward export terminals rather than only regional or national pipeline markets, which is a distinct demand dynamic from gas basins further from the coast.

High cost, high initial rate — and a real decline to match

Haynesville wells are among the most expensive shale wells to drill in the country because of their depth and pressure, but they often deliver very high initial production rates to match. Like most shale wells, they also decline steeply in the first year or two before settling into a longer tail, so the same decline-curve caution that applies to Bakken or Permian wells applies here as well: don't extrapolate a new well's first-month rate in a straight line.

The high cost side of this equation matters for development pace — operators are more selective about when to drill Haynesville wells compared to cheaper basins, generally waiting for stronger gas pricing or firm demand commitments before committing capital, which affects how quickly undeveloped acreage here is likely to see activity.

LNG demand and why it matters more here than in most gas basins

The Haynesville sits within reasonable pipeline distance of the growing cluster of LNG export terminals along the Gulf Coast in Louisiana and Texas, and a meaningful share of new Haynesville development in recent years has been tied to supplying gas for export rather than purely domestic use. LNG demand adds a new, structurally different buyer for this gas compared to a decade ago.

That said, LNG demand growth is not guaranteed to be smooth — new export capacity comes online in steps, not continuously — so a calculator should treat this as a supportive but not certain tailwind, reflected in a moderately optimistic gas price assumption rather than an aggressive one.

Texas side versus Louisiana side

The Haynesville straddles the Texas-Louisiana line, and the two states differ in severance tax treatment, regulatory bodies, and permitting processes — Texas Railroad Commission on one side, Louisiana Department of Energy and Natural Resources (formerly DNR/Office of Conservation) on the other. Entering the correct state lets a calculator account for these differences rather than treating the whole play as one uniform jurisdiction.

Core development has historically concentrated in specific parishes and counties on both sides, so activity level should be checked at the parish or county level, not assumed uniformly across the whole play.

Dry gas means no oil cushion, but strong per-well volumes

There is essentially no oil production in the Haynesville — this is a dry gas play through and through — so royalty income tracks gas pricing directly with nothing to offset a weak stretch. What offsets that exposure somewhat is the sheer volume some of these wells can produce when gas prices and demand support active drilling, which is part of why the play has repeatedly cycled between boom and slowdown as gas prices moved. A calculator run for this basin should weight recent gas pricing trends heavily, and treat any single strong or weak month as one data point rather than the whole picture.
