The Largest Oil And Gas Reserve In The Amazon Completes 39 Years Of Production And Continues To Supply Cities In The North And Northeast, Increasing The Use Of Natural Gas And Reducing Environmental Impacts.

The production of oil in the interior of the Amazon continues to play a strategic role for the energy supply of the country. The Urucu base, located in Coari, has become one of Petrobras’ most important assets in the North region. Even after almost four decades of operation, the area continues to expand its impact, ensuring the supply of natural gas, LPG, and high-value derivatives for several municipalities.

Meanwhile, the modernization of structures and the growing adoption of natural gas instead of diesel reinforces the relevance of the reserve for a more sustainable energy matrix.

Urucu Region Maintains Prominent Position With High-Quality Oil

The discovery of the oil and gas reserve in the Coari area occurred in 1986. Just two years later, in 1988, Petrobras began exploring the field, which quickly became a reference for light oil production — a type valued for its low presence of heavy metals and its ability to produce high-quality fuels, such as aviation kerosene and better quality diesel oil.

Today, of the 100 wells drilled, 75 remain active. They operate daily and account for the continuous production that reaches the major cities of the North region. The state technicians emphasize that local oil maintains high standards and continues to contribute to industrial and domestic supply.

Efficient Logistics Ensures The Transport Of Oil And Gas To The Capitals Of The Region

The oil and gas reserve in the Amazon occupies about 332 million square meters. From this area, energy transportation is carried out through a complex logistical structure that begins in the heart of the forest.

LPG (liquefied petroleum gas) travels through a 285 km pipeline to Coari. From there, vessels take the product directly to Manaus, supplying families and industries. Natural gas flows approximately 700 km through pipelines, crossing the Solimões and Negro rivers. The route passes through important municipalities such as:

Codajás
Anori
Anamã
Caapiranga
Manacapuru
Iranduba

This continuous transport ensures that the North region receives energy in a stable manner, even in isolated areas.

Natural Gas Replaces Diesel And Reduces Environmental Impacts In The Amazon

The adoption of natural gas as an alternative to diesel has changed the energy profile of several cities. According to Hilter Bandeira, general manager of the unit, 12 thermoelectric plants in the Amazon have already made this switch. In Manaus, seven units use natural gas. In the interior, another five have also migrated to this cleaner source.

The environmental impact is lower, and energy efficiency is higher. Furthermore, the continuous supply reinforces the energy security of the region.

“We deliver to Manaus daily between 5 and 6 million m³ of natural gas, which contribute to thermal energy generation and also for use in condominiums, industries, and vehicles,” explains Hilter.

Petrobras intends to expand exploration. The company plans to drill 22 new wells starting in 2026. However, the start depends on the completion of environmental studies and the approval of licenses. The proposal aligns with the growing demand for cleaner and diversified energy sources, a goal that places the Amazon at the center of the country’s energy transition.

Natural Gas Replaces Diesel And Reduces Environmental Impacts In The Amazon

For 45 years, Spain and Morocco have been trying to connect Europe to Africa through a project of just 14 kilometers in the Strait of Gibraltar, and an active tectonic fault on the seabed continues to make the project nearly impossible.

At just 14 years old, a boy creates a system without energy, using steel pipes buried in the ground, that irrigates seedlings with moisture from the air, to combat the water scarcity threatening reforestation in northern China.

Where there was only sand and wind at 40 degrees, China built a megacity of 500,000 inhabitants with farms, wineries, and universities in the middle of the desert using melted glacier water from hundreds of kilometers away.

Archaeologists found giant shoes over 30 centimeters near Hadrian’s Wall that survived nearly two thousand years buried and now raise a mystery: who were these Roman soldiers so different from the others?

Like Generation Z, young Mark Zuckerberg “had no sense of small talk” and “would just stare at you,” says the investor.

With mortar, earth, and PU paint, a simple technique becomes a trend for renewing old floors without demolition, offering high resistance, professional finish, and very low cost.

The noise law will no longer be in effect at 10 PM starting in June with a new rule valid during the 2026 World Cup.

Australia accelerates the search for foreign workers in 2026 with an official list of in-demand professions that includes drivers, programmers, and nurses, salaries starting from AUD 76,515 per year, and visas that can lead to permanent residency.

Harvard scientists have created a tissue exoskeleton that does not look like an exoskeleton, with no rigid parts and reduced weight, using flexible cables and miniaturized motors to assist the ankle and hip, reducing the effort of walking by up to 23% in controlled tests.

Meta’s new smart glasses are not just for seeing; they use artificial intelligence, analyze your food, summarize messages, and can even change the way you work in professions like engineering.
