Chevron's $53B acquisition of Hess Corp. sees hiccup

Chevron warned Monday that its pending $53 billion acquisition of Hess may be in jeopardy because it will require the approval of Exxon Mobil and a Chinese national oil company, which both hold rights to development of an oil field off the coast of the South American nation Guyana.

The disclosure in a filing with the Securities and Exchange Commission raised investor qualms, depressing shares of both Chevron and Hess. Chevron's stock price fell 3% Tuesday morning before rebounding; Hess stock lost 4% of its value but bounced back slightly.

Chevron's acquisition of Hess would add this major oil field in Guyana as well as shale properties in the Bakken Formation in North Dakota. Guyana is a country of 791,000 people that is poised to become the world’s fourth-largest offshore oil producer, placing it ahead of Qatar, the United States, Mexico and Norway. It has become a major producer in recent years, with oil giants including Exxon Mobil, China’s CNOOC, and Hess squared off in a heated competition for highly lucrative oil fields in northern South America.

Chevron said it's been engaged in discussion with Exxon and CNOOC, aka China National Offshore Oil Co. Both companies hold rights of first refusal for decisions regarding the oil field in question, known as the Stabroek Block. Exxon Mobil operates the Stabroek Block and holds 45% interest. Hess holds 30% interest, and CNOOC holds the remaining 25% interest. Production capacity at the field is expected to reach more than 1.2 million barrels per day by the end of 2027, Exxon said in November.

If those discussions and subsequent arbitration fail to set aside those first refusal rights, Chevron said, “the merger would not close.”

Researchers from the University of Houston — along with a Hawaiian company — have received $3.3 million in funding to explore artificial intelligence-backed subsurface sensing system for safe and efficient underground power line installation.

Houston's power lines are above ground, but studies show underground power is more reliable. Installing underground power lines is costly and disruptive, but the U.S. Department of Energy, in an effort to find a solution, has put $34 million into its new GOPHURRS program, which stands for Grid Overhaul with Proactive, High-speed Undergrounding for Reliability, Resilience, and Security. The funding has been distributed across 12 projects in 11 states.

“Modernizing our nation’s power grid is essential to building a clean energy future that lowers energy costs for working Americans and strengthens our national security,” U.S. Secretary of Energy Jennifer M. Granholm says in a DOE press release.

UH and Hawaii-based Oceanit are behind one of the funded projects, entitled “Artificial Intelligence and Unmanned Aerial Vehicle Real-Time Advanced Look-Ahead Subsurface Sensor.”

The researchers are looking a developing a subsurface sensing system for underground power line installation, potentially using machine learning, electromagnetic resistivity well logging, and drone technology to predict and sense obstacles to installation.

Jiefu Chen, associate professor of electrical and computer engineering at UH, is a key collaborator on the project, focused on electromagnetic antennas installed on UAV and HDD drilling string. He's working with Yueqin Huang, assistant professor of information science technology, who leads the geophysical signal processing and Xuqing Wu, associate professor of computer information systems, responsible for integrating machine learning.

“Advanced subsurface sensing and characterization technologies are essential for the undergrounding of power lines,” says Chen in the release. “This initiative can enhance the grid's resilience against natural hazards such as wildfires and hurricanes.”

“If proven successful, our proposed look-ahead subsurface sensing system could significantly reduce the costs of horizontal directional drilling for installing underground utilities,” Chen continues. “Promoting HDD offers environmental advantages over traditional trenching methods and enhances the power grid’s resilience.”
