SLB Acquires Kelvion for $4.1B: Air Cooling Fails AI Math, Oilfield Engineers Win

SLB announced it will acquire German thermal-management firm Kelvion in a deal valued at about $4.1 billion, combining $3.4 billion in cash with the assumption of roughly $0.7 billion in existing debt. The acquisition follows SLB’s stated thesis that heat removal—not chips or software—is the key infrastructure bottleneck for AI systems. The agreement, announced Monday, is expected to close in the first half of 2027, subject to regulatory approvals. The article emphasizes why air cooling cannot scale with current AI rack densities, citing NVIDIA Blackwell power levels such as 120–130 kilowatts per GB200 NVL72 rack and describing required airflow for air cooling as physically impractical in a standard enclosure.
