Natural gas prices are hitting rock bottom, with Henry Hub averaging a mere $1.49 in March 2024, the lowest monthly average since 1997. Shale operators are responding by curtailing production. Chesapeake, a leading producer, started the trend with cuts announced in early March. Other companies like Coterra Energy, Comstock Resources, EQT, and CNX Resources have followed suit, reducing drilling activity or implementing production curtailments.
ADI anticipates lower U.S. gas production
Based on these announcements and ADI’s natural gas price forecasts for 2024, U.S. production is expected to fall by more than 3 billion cubic feet per day (Bcfd) this year. Lower 48 production has already dipped from 104.7 Bcfd in February 2024 to 102.1 Bcfd, with Appalachia experiencing the most significant decline. Haynesville isn’t far behind, with E&P operators like Comstock announcing cutbacks.
Renewed interest in gas-to-liquids (GTL)
Amidst production cuts, two news items caught ADI’s attention, signaling a potential resurgence of GTL technology. First, Diamondback Energy, a prominent Permian E&P company, is partnering with Verde Clean Fuels to build a natural gas-to-gasoline facility in Martin County, Texas. This facility, utilizing Verde’s STG+ process, is expected to produce 3,000 barrels of gasoline daily and be operational by late 2025 or early 2026.
The STG+ process, developed by Primus Green Energy a few years ago, is a small-scale GTL technology that converts natural gas into either methanol or gasoline. The Martin County plant will utilize flared natural gas as feedstock, and the produced gasoline will be sold to Permian Basin refiners and distributors.
GTL plants convert natural gas into liquids like naphtha, diesel, and lubricants. This process involves gasification to produce syngas, which is then converted into liquid hydrocarbons using the Fischer-Tropsch process. A broader definition of GTL encompasses the conversion of natural gas to methanol, followed by further processing into gasoline using technologies like ExxonMobil’s methanol-to-gasoline process.
Adding to the GTL revival, Calgary-based Cerilon plans to build a complex in Trenton, North Dakota, for converting natural gas into diesel, jet fuel, and lubricants. In March 2024, they announced partnerships with Chevron, Worley, and ABB for equipment, technology licensing, and engineering, procurement, and construction (EPC) services. This 24,000 barrel-per-day plant, with a capex of $2.8 billion, is expected to be completed in 2028.
ADI revisits GTL economics
These developments remind ADI Analytics of the period over a decade ago when the North American shale gas revolution was just unfolding. The surging natural gas production led us to launch our first multi-client study on gas monetization in 2011. This study attracted numerous companies, from oil majors to project developers and shale independents. It also sparked a wave of consulting projects focused on various gas monetization options over the following years.
Back then, several proposals emerged for gas monetization projects utilizing LNG, GTL, CNG, methanol, and other technologies (refer to Exhibit 1). ADI conducted a comprehensive assessment comparing these options across factors like cost, economic viability, technological maturity, operational risks, and commercial models. This analysis considered how each option would fare for project developers in different regions of North America, taking into account both existing and new infrastructure requirements.
