Eneva, Driven by Previous Discoveries, Decided to Drill the Third Well in Block AM-T-84, Located in the Amazon Basin, Resulting in the Discovery of New Signs of Natural Gas in the Region
This week, Eneva announced that signs of natural gas were found in well 3-ENV-35D-AM, located in the onshore block AM-T-84, in the Amazon Basin – the largest in the country. This discovery is already the third made by the company in this block in less than a year.
Eneva’s exploratory campaign in the Amazon Basin began in 2019, with the aim of liquefying the natural gas found in the Azulão field and transporting it to the state of Roraima, where it will supply a thermoelectric plant built to provide electricity to the region. In this regard, it is worth recalling that the Amazon holds 50% of all Brazilian reserves for the exploration of natural gas on land.
In Addition to the First Two Discoveries in Block AM-T-84, During the Last Months of November and May, Eneva Also Found Signs of Oil and Natural Gas in the Neighboring Block AM-T-85
In November of last year, while drilling the pioneering well in block AM-T-84, Eneva had already informed the National Agency for Petroleum (ANP) about the existence of signs of oil and natural gas in the region. Then, in May of this year, the company’s second discovery was announced, which occurred in the second well of the area, named 3-ENV-33D-AM.

Furthermore, in April, Eneva also reported the finding of signs of oil and natural gas in well 1-ENV-31D-AM, located in another neighboring block, AM-T-85. Thus, it becomes evident that the exploratory program in the Amazon has contributed to the expansion of the company’s reserves.
Eneva’s Natural Gas Reserves Have More Than Doubled Thanks to the Exploratory Program in the Amazon Basin
Since the end of 2021, Eneva’s natural gas reserves have more than doubled, according to an audit conducted by the independent consulting firm Gaffney, Cline & Associates (GCA). In four months, the volumes rose from 7.109 billion cubic meters to 14.8 billion cubic meters.
The document produced by GCA pertains to the gas and condensate field of Azulão, in production, and to the exploratory blocks AM-T-84 and AM-T-85, included in the Assessment and Discovery Plan (PAD) Anebá.
About Eneva
Eneva is the largest private natural gas operator in the country. Its exploration and production assets are located in the states of Amazonas and Maranhão, with a total concession area of over 60,000 km².
The company explores and produces natural gas according to power plant demand. According to them, onshore non-associated gas is more competitive regarding discovery, development, and production costs per cubic meter, resulting in energy generation with more attractive costs for the Brazilian electricity system.
In addition to the already mentioned activities, Eneva also operates in the production of safe and competitive energy for all of Brazil. The company has a thermal park with a contracted installed capacity of 3.7 GW, with assets located in the states of Maranhão, Ceará, and Roraima.
Finally, thanks to its experience in the energy and natural gas market, Eneva also works on developing tailored energy solutions based on each client’s needs. As such, solutions aimed at energy commercialization, energy management, or, finally, supplying natural gas to companies are offered.
