Black Stone Minerals and Caturus Energy Announce New Development Agreement in the Shelby Trough

HOUSTON--(BUSINESS WIRE)-- Black Stone Minerals, L.P. (NYSE: BSM) (“Black Stone,” “BSM,” or “the Partnership”) announced today it has entered into a 220,000 gross acre development agreement with an affiliate of Caturus Energy, LLC (“Caturus”) within the Shelby Trough and Haynesville Expansion. The agreement creates a multi-year drilling program designed to advance development of BSM’s acreage under Caturus’ operating expertise while supporting the growing demand for natural gas across the Gulf Coast region.

Under the terms of the agreement, Caturus has the opportunity to escalate its drilling program over the next six years and drill a step out pilot and test well in the first two years to continue operating across the full footprint. Activity will begin with approximately two gross (0.2 net) wells in 2026 and ramp to approximately 12 gross (0.8 net) wells annually by the end of the six years, supported by minimum annual lateral-foot requirements, all net to BSM’s interest.

BSM currently manages approximately 40,000 undeveloped net acres within this contract area, with line of sight to additional acquisitions to further increase BSM’s net interest across the area.

Management Commentary

Thomas L. Carter, Jr., Black Stone Minerals’ Chairman, Chief Executive Officer, and President, commented, “We are pleased to join forces with another top-notch capital provider and technically skilled operator focusing on the East Texas Haynesville/Bossier play alongside a constructive outlook on the gas market. These elements, along with our significant mineral ownership and control of the hydrocarbon resource, are foundational to a meaningful long-term gas development program.

BSM has been assembling a large, high interest mineral position in East Texas for over 100 years, with substantial capital deployed aggregating its mineral assets, mostly from timber companies, to create a massive development footprint. With our core spread of mineral fee acreage, we can exercise significant control over when and where development occurs and can work with capital providers and operators to create an integrated and structured operation.

As we continue to add to our position, these efforts have resulted in over 200,000 net acres covered by announced development agreements in the area, representing an estimated 20 years of drilling inventory in the Haynesville and Bossier on which BSM expects to receive royalties. Caturus, controlled by Kimmeridge, brings front line operating and technical skills to expedite the extraction of BSM reserves.

We look forward to working with Caturus, and we remain focused on other significant projects in the queue to further enhance our existing stable of large-scale development contracts.”

David Lawler, Chief Executive Officer of Caturus commented, “This transaction represents an important milestone in our strategy to build America’s leading integrated natural gas platform. With the addition of this Haynesville development opportunity to our South Texas upstream position and our planned liquefaction terminal in Louisiana, we are advancing our vision of delivering a differentiated wellhead-to-water model, enabled by our proximity to the Gulf Coast. We have a long and productive history of developing properties with the BSM team, and we will work together to safely meet the world’s growing demand for responsibly sourced natural gas.”
