Tuscaloosa Marine Shale Mineral Rights
The TMS boom ran roughly 2010 to 2015 and largely stalled out; we underwrite what's actually producing today, not what was projected a decade ago.
The Tuscaloosa Marine Shale runs across southwest Mississippi and into east-central Louisiana, with Wilkinson, Amite, and Pike counties in Mississippi seeing the heaviest activity during the play's development window. Unlike some of the longer-running basins we cover, the TMS had a comparatively short and difficult boom: operators drilled a meaningful number of horizontal wells between about 2010 and 2015, but high water cuts, well cost, and falling oil prices caused most companies to pull back sharply, and large-scale development never resumed at the pace originally expected.
That history matters for pricing. We are not underwriting a play with active new drilling; we are underwriting a set of existing wells, most now several years into decline, plus a large amount of leased or once-leased acreage where the original lease may have expired or be nearing expiration without a well ever being drilled.
Why TMS wells decline the way they do
High water cut has been one of the defining challenges of this play since its earliest wells, and it affects net economics more than in many other oil shale plays, since water handling and disposal costs eat into revenue even as oil volumes hold up reasonably well. We look closely at net revenue after deductions, not gross oil production, when building a decline curve for a TMS interest.
Because the drilling window here was compressed into a few years, most producing wells behind current interests are in a similar stage of their decline, which actually makes cross-comparison a bit easier for us than in a basin where wells range from five to fifty years old.
What happened to leases that never got drilled
A significant amount of TMS acreage was leased during the boom years but never drilled, and many of those original leases have since expired under their own terms, reverting the mineral rights back to unleased status. If you signed a lease around 2011 to 2014 and have not received a bonus, delay rental, or royalty check in years, there's a real chance that lease has lapsed, which actually simplifies a sale to us since we'd be buying a clean, unencumbered mineral interest rather than one still tied up in an old lease.
We verify lease status directly against the courthouse record rather than assuming based on what a seller recalls signing years ago, since delay rental and held-by-production language varies from lease to lease.
Being direct about where this play stands
We are not going to suggest the TMS is on the verge of a renewed drilling boom, because we don't have evidence of that. What we can say is that a subset of wells drilled during the original window continue to produce, and those interests have real, if modest, ongoing value that we price off actual trailing production. For unleased acreage with no nearby producing well, value is limited and we say so rather than dressing up an offer with speculative upside.
This is one of the more straightforward conversations we have with sellers precisely because the play's history is public and well documented; we'd rather walk through it honestly than oversell either the past or the future.
Courthouse notes across Mississippi and Louisiana counties
Wilkinson, Amite, and the surrounding Mississippi counties recorded a high volume of leases in a short window during the boom, and it is worth checking the chancery clerk's index for any subsequent release of that lease if you haven't heard from an operator in years. On the Louisiana side, parish conveyance records follow a similar pattern, and we check both jurisdictions as part of our standard title review.
Questions Owners Ask the Acquisition Desk
Is the Tuscaloosa Marine Shale still being actively drilled?
Not at the pace it was during the 2010-2015 boom. Most current activity is limited, and we underwrite interests based on existing production rather than assuming new development.
My lease from around 2012 never resulted in a well. Is it still valid?
It may have expired under its own terms if no well was drilled and no delay rentals were paid. We check the courthouse record to confirm current lease status before pricing your interest.
Why does my TMS well's oil check seem low relative to its production volume?
High water cut is common in this play, and water disposal costs are typically deducted before you're paid, which reduces net revenue relative to gross oil volume.
Will you buy unleased minerals with no nearby producing well?
We'll consider it, but we're upfront that value on undeveloped TMS acreage is limited given the play's development history. We won't inflate an offer with speculative future drilling that isn't supported by current activity.
How do you value a TMS interest tied to a well several years into decline?
We build a decline curve from trailing net production and revenue, weighted toward the most recent data, and apply a standard time-value discount. It's the same framework we use across any mature oil shale interest.
