Petrobras teams up with Houston co. to improve efficiency in drilling

offshore optimization

Slovakian geothermal drilling technology company GA Drilling, whose U.S. headquarters is in Houston, has teamed up with Brazilian energy giant Petrobras to reduce well construction costs and well-drilling risks.

Under the new partnership, GA Drilling will work with Petrobras’ R&D center to roll out an autonomous drilling system that enables drilling at offshore wells from a light vessel instead of a costlier semi-submarine or drill ship.

“Taken together, the benefits of our drilling technologies equal better efficiency, leading to lower costs, [a] smaller operational footprint, and ultimately lower risk overall,” Igor Kočiš, co-founder and CEO of GA Drilling, says in a news release.

GA Drilling says its drilling system improves drilling efficiency and enables replacement of conventional drill pipes with lower-risk tubes. Features of the system include drilling automation and control systems, and real-time communications.

In April 2024, GA Drilling announced it had closed on $15 million in funding. Investors included Houston-based oil and gas drilling contractor Nabors Industries, the newly established Underground Ventures geothermal investment fund, and Slovakian venture capital firm Neulogy Ventures.

A year earlier, GA Drilling conducted the first public demonstration of its Anchorbit drilling tool at a Houston test well owned by Nabors. The tool is designed to simplify and improve drilling into high-temperature hard rock formations.

Why this entrepreneur believes Houston should lead resilience technology alongside the energy transition

When it comes to developing resilience technology, Houston startup founder Ali Mostafavi knows he's in the right place.

Mostafavi, a civil and environmental engineering professor at Texas A&M University, co-founded Resilitix.AI two years ago, and with the help of his lab at A&M, has created a platform that brings publicly available data into AI algorithms to provide its partners near-real time information in storm settings.

"We are very excited that our company is Houston based," he says on the Houston Innovators Podcast. "We should not be just ground zero of disasters. We have to also be ground zero for solutions as well. I believe Houston should be the hub for resilience tech innovation as it is for energy transition.

"I think energy transition, climatetech, energy tech, and disaster tech go hand in hand," Mostafavi continues. "I feel that we are in the right place."

Earlier this month, Mostafavi got an unexpected chance to pilot his company's data-backed and artificial intelligence-powered platform — all while weathering one of Houston's most impactful storms.

As Hurricane Beryl came ashore with Houston on its path, Mostafavi says he had the opportunity to both test his technology and provide valuable information to his community during the storm.

"We were in the process of fine tuning some of our methods and algorithms behind our technology," Mostafavi says. "When disasters happen, you go to activation mode. We put our technology development and R&D efforts on hold and try to test our technology in an operational setting."

The platform provides its partners — right now, those include local and state organizations and emergency response teams — information on evacuation reports, street flooding, and even damage sustained based on satellite imagery. Mostafavi says that during Beryl, users were wondering how citizens were faring amid rising temperatures and power outages. The Resilitix team quickly pivoted to apply algorithms to hospital data to see which neighborhoods were experiencing high volumes of patients.

"We had the ability to innovate on the spot," Mostafavi says, adding that his own lack of power and internet was an additional challenge for the company. "When an event happens, we start receiving requests and questions. ... We had to be agile and adapt our methods to be responsive. Then at the same time, because we haven't tested it, we have to verify that we are confident (in the information we provide)."

On the episode, Mostafavi shares how Hurricane Harvey — which occurred shortly after Mostafavi moved to Houston — inspired the foundation of Resilitix, and he also explains how he plans to grow and scale the business.

Expert weighs in on fire protection standards in hydrogen industry growth

guest column

As First State Hydrogen continues to advance its groundbreaking clean hydrogen production facility in the U.S., the spotlight intensifies as hydrogen becomes an increasingly key player in the energy transition.

With the projected uptick of new hydrogen production and handling projects, let's explore hydrogen fire protection, reflect on the measures and standards established to mitigate risks, and ensure that the hydrogen economy thrives.

The challenges of hydrogen fire protection

As the hydrogen industry experiences a boom, the issue of fire protection emerges as a critical concern. It's important to note that hydrogen fires can pose a significantly higher risk than traditional fuel fires, burning hotter and more rapidly due to their higher outflow rates. The diverse range of storage and transport options, from cryogenic liquids to high-pressure cylinders, further complicates safety measures. This underscores the industry's urgent need to prioritize risk mitigation for common hydrogen applications, such as high-pressure cylinders used in fuel-cell vehicles and data centers, to ensure safety as this energy source scales up.

Hydrogen jet fire test results

The author's company, a global leader in paint and coatings, recently tested an industry leading, flexible epoxy intumescent passive fire protection (PFP) coating to evaluate the material response against high pressure hydrogen jet fires to determine if current ISO jet fire standards are adequate for the challenges hydrogen poses. Collaborating with the United Kingdom's Health and Safety Authority, they conducted hydrogen jet fire tests at a specialized facility. The team replicated conditions of high-pressure hydrogen leaks and their effects on steel and protective coatings. The initial tests revealed unprotected steel reaching critical temperatures rapidly under hydrogen fires. The steel coated with advanced PFP coatings proved highly effective. The PFP coatings help keep steel well below critical temperatures throughout the exposure, indicating their potential to protect against structural failures during hydrogen fires.

These initial tests can contribute to setting standards for hydrogen fire protection. The results offer safety experts critical data for better protecting industrial environments against high-pressure hydrogen jet fires.

A call for a fire protection standard

The hydrogen industry currently relies on oil and gas regulations for specialized fire protection. While safety experts actively debate whether these standards can be adapted or whether entirely new criteria are necessary, industry collaboration remains key. Paint and coating companies, international standard organizations, safety groups, and energy regulators are all actively involved in assessing the adaptability of existing standards for hydrogen fires. The initial tests show promising results, suggesting that current oil and gas fire protection measures might be adapted for hydrogen fire protection, potentially leading to standards for the growing hydrogen industry.

Developing fire protection standards for the hydrogen industry remains a collective industry responsibility. Safety engineers, industry specialists, non-government officials (NGO), and policymakers must work together to ensure the hydrogen industry advances safely and responsibly. The paint and coatings industry, in particular, will play a crucial role in creating these standards. Leveraging their expertise in protective coatings, they can meet hydrogen's unique needs, from anti-corrosion to chemical resistance and passive fire protection.
