SLB and Shearwater Launch Amapá 3D Seismic Survey with Amazon Warrior Vessel After Petrobras Discovery Rekindles Interest in the Equatorial Margin. High-Density Data Will Map the Subsurface and Could Guide New Drilling and Future Exploration Rounds
Just weeks after Petrobras announced the presence of hydrocarbons at the Morpho well, in ultradeep waters of Amapá, two international giants in technology and geophysics launched a new project into the sea to visualize, in three dimensions, what lies beneath one of the most closely monitored areas of the Equatorial Margin. According to information published by Offshore Energy on September 8, 2026, SLB and Shearwater GeoServices have initiated the Amapá 3D seismic survey, located approximately 130 kilometers from the Morpho well, using the seismic vessel Amazon Warrior.
Moreover, SLB’s official announcement highlights the strategic importance of this move: the company refers to the project as one of its most significant investments in exploration data in the deep Atlantic margin. The acquisition will utilize Shearwater’s Isometrix marine seismic technology, while SLB will handle the processing and creation of subsurface images using advanced methods, including elastic full-waveform inversion.
However, there is an important distinction from the outset. The new survey does not mean that SLB and Shearwater have discovered oil in Amapá, nor that new drilling has commenced. This is a multi-client seismic study aimed at producing detailed subsurface images that can be sold or licensed to various companies interested in assessing exploration opportunities. Similarly, Petrobras announced the identification of hydrocarbons at Morpho, but still needs new data and wells to gauge the accumulation and prove its commercial viability.

Everything Changed in August When Petrobras Drilled 175 km Off the Amapá Coast and Found Hydrocarbons at Morpho Well
The timing chosen for launching Amapá 3D is not coincidental. On August 14, 2026, Petrobras announced it had found a hydrocarbon-bearing interval while drilling the Morpho, officially identified as 1-BRSA-1405-APS, in block FZA-M-59, in the Amazonas River Mouth Basin.
The well is located approximately 175 kilometers off the coast of Oiapoque in Amapá, and nearly 500 kilometers from the mouth of the Amazon River. Additionally, drilling occurs under a water depth of 2,886 meters, placing the activity within the realm of ultradeep water.
According to Petrobras, the presence of hydrocarbons was indicated by electrical profiles and signs observed in the rocks. At that time, the state-owned company stated it would continue to evaluate the area. Therefore, despite the enormous interest generated by the news, there is still no public basis to regard Morpho as a commercial field with proven reserves or guaranteed production.
Even so, the geological impact was immediate. Andrea Lovatini, Vice President of Exploration Data and Geosolutions at SLB, stated that the Morpho discovery has brought renewed attention to offshore exploration in Amapá. This way, the company sees an opportunity to provide interested firms with more accurate images of the subsurface before they take the risk of drilling new wells.
This is precisely how major frontiers of offshore operations typically progress: geological and seismic data emerge first, followed by prospects, investment decisions, and only after this sequence come wells that can confirm or undermine expectations.
Amazon Warrior Takes Center Stage to Produce a Type of “3D Tomography” of the Seafloor Without the Need to Drill Each Point
3D seismic operates, in simplified terms, like a gigantic imaging tool for the subsurface.
The seismic vessel traverses planned lines in the ocean while acoustic sources generate waves that penetrate different geological layers. Subsequently, sensors capture the signals reflected by these structures. Computational systems then transform a massive amount of data into images capable of revealing folds, faults, sedimentary structures, and potential geological traps.
In Amapá, Shearwater will utilize its Isometrix technology to acquire high-density broadband data aboard the Amazon Warrior. Subsequently, SLB will process the information and apply advanced imaging workflows, including full-waveform elastic inversion.
This technique attempts to numerically reproduce how seismic waves traversed the subsurface. Consequently, in geologically complex areas, it can provide a more detailed view than traditional processing techniques.
However, no seismic image can fully replace drilling.
It can show promising structures and assist geologists in deciding where to drill, but only a well can directly confirm what fluids exist within the rock and under what conditions.
Therefore, Amapá 3D reduces uncertainties. It does not eliminate exploratory risk.
Project is Located About 130 km from Morpho and Could Change How Companies Assess Little-Known Blocks Along the Equatorial Margin
The distance between the two initiatives explains much of the attention.
According to SLB, the area of the new survey is approximately 130 kilometers from the Morpho well. Furthermore, the company describes this portion of the basin as still underexplored and lacking modern subsurface data.
By launching the survey soon after Petrobras’s discovery, SLB and Shearwater aim to fill exactly this gap.
Companies interested in blocks in the region will be able to use the data set to compare structures, identify prospects, and estimate which areas would justify much more expensive drilling investments.
In this sense, seismic data serves as a kind of financial filter.
An exploratory well in ultra-deep waters can cost hundreds of millions of reais or more, depending on location and complexity. Therefore, before hiring a rig and drilling kilometers of rock, companies seek to minimize geological uncertainty.
The better the image of the subsurface, the more selective this choice can be.
At the same time, the technology does not solely determine whether drilling will take place. Environmental licensing, block acquisition, business strategy, costs, and oil prices also weigh in the decision.
“Multi-client” changes the game: SLB and Shearwater invest in data now to later offer it to different oil companies
There is also an important commercial detail behind the project.
The Amapá 3D survey is classified as a multi-client survey.
This means that the data is not produced exclusively for a single oil company under a traditional contract. Instead, geophysical companies build a large regional library and can license the results to multiple clients, according to their exploratory interests.
This strategy makes sense primarily in new frontiers.
If several companies believe that a basin might contain opportunities, they all need to answer similar questions: how are the sedimentary layers organized? Where are the structures capable of trapping hydrocarbons? Which areas have a better potential-to-risk ratio?
Instead of each company repeating the entire survey, a multi-client set can serve multiple interested parties.
Additionally, Irene Waage Basili, CEO of Shearwater, stated that the combination of Isometrix technology with SLB’s imaging flows aims to create a premium regional data set, capable of supporting exploration and future licensing activities in Brazil’s Equatorial Margin.
Consequently, the project does not only consider blocks that already have operators. It can also influence the evaluation of areas that may come up in future bidding rounds.
Equatorial Margin extends approximately 2,200 km and has become a key area for replenishing reserves as pre-salt growth slows
The region where Morpho was drilled is part of a much larger frontier.
The Brazilian Equatorial Margin spans about 2,200 kilometers and includes the basins of Foz do Amazonas, Pará-Maranhão, Barreirinhas, Ceará, and Potiguar, according to information from Petrobras itself.
Interest has increased primarily for two reasons.
First, pre-salt will continue to be fundamental for national production for years to come; however, the industry is already addressing the need to find new areas capable of replacing reserves that decline over time.
Second, discoveries made in northern South American countries, particularly Guyana and Suriname, have heightened interest in the geology of the region’s Atlantic margin.
However, regional geological similarity does not mean that Brazil will necessarily replicate Guyana’s successes. Oil systems can vary significantly even in relatively close areas.
Therefore, new seismic surveys are gaining importance.
They help replace generic comparisons with data specific to Brazilian geology.
Moreover, this trend occurs as other companies ramp up investments in seismic data. In 2025, for example, TGS announced the second phase of its PAMA survey, covering approximately 11,500 square kilometers in the Pará-Maranhão Basin, following a first phase of 19,343 square kilometers.
In other words, interest is not concentrated in just a single block.
The Discovery of Morpho Opened the Door, but IBAMA Still Controls Every New Step Because Exploration Occurs in an Environmentally Sensitive Area
The geological race does not eliminate the environmental dimension.
The Equatorial Margin is one of the most contested areas in Brazilian energy politics. The licensing of block FZA-M-59 went through years of discussion before IBAMA authorized exploratory drilling in 2025.
Additionally, following the discovery of Morpho, Petrobras sought authorization to proceed with new wells in the area. In September 2026, IBAMA authorized three new exploratory drilling projects in the Foz do Amazonas Basin, requiring an updated schedule and a review of elements related to risk analysis.
Therefore, discovering hydrocarbons does not automatically create a production field.
First, new wells need to delineate the accumulation and clarify its quality.
Next, the company must assess recoverable volume, productivity, costs, logistics, and economic feasibility.
Moreover, any production projects will require new licensing stages.
This is precisely why analysts consulted after Morpho classified the discovery as significant but emphasized that its immediate impact remains limited, given that fundamental information about volume and marketability is still lacking.
Thus, the Amapá 3D arrives at a time when the geology is becoming more intriguing, yet many economic and environmental questions remain unanswered.
The true prize may not just be finding oil, but creating a new map for billions in future exploration decisions
A seismic survey rarely receives the same public attention as a discovery.
It does not produce barrels.
It does not inaugurate a platform.
Nor does it confirm reserves.
However, it can influence where billions of dollars will be invested or avoided over the coming years.
This is the strategic value of Amapá 3D.
SLB states that the dataset should support prospectivity assessment, future exploratory activities, and licensing opportunities. Therefore, the project creates a new layer of information just as companies begin to pay closer attention to Amapá.
Furthermore, the selection of the Amazon Warrior and advanced technologies indicates that companies are betting on detailed coverage, rather than just basic regional acquisition.
If the data reveals interesting structures, new clients may direct studies toward specific blocks.
If the images are less promising, they will still hold value, as they can prevent companies from spending fortunes drilling in unsuitable targets.
In both cases, information reduces risk.
That is why submarine infrastructure begins long before the installation of Christmas trees, manifolds, and pipelines. In new frontiers, it is built first within geological models constructed from seismic data.
Morfo is 2,886 meters below sea level, but the biggest mystery lies several kilometers deeper
The water column of the well is impressive in its own right.
2,886 meters.
However, after crossing nearly three kilometers of ocean, the drill bit still needs to penetrate several additional kilometers of sedimentary rock to reach its exploratory targets.
It is in this invisible environment that SLB and Shearwater aim to obtain a clearer image.
The Amazon Warrior does not need to drill the seabed to conduct the survey. Instead, it will pass over the area, acquiring signals that will later be transformed into three-dimensional volumes of the underground.
In this way, geologists can digitally “navigate” through structures and compare different horizons.
This type of information may also become decisive for port and offshore logistics in the future if commercial discoveries lead to the construction of bases, hiring vessels, and the development of production projects.
However, that scenario is still many steps ahead.
Today, the stage is all about understanding.
The launch of Amapá 3D doesn’t confirm another discovery, but reveals something important: companies are already spending to better understand what exists around Morpho
This might be the most relevant takeaway from the announcement.
In August, Petrobras found hydrocarbons at Morpho, 175 km off the coast of Amapá and under 2,886 meters of water. Less than a month later, SLB and Shearwater began a 3D seismic survey approximately 130 kilometers from the well, categorizing the initiative among SLB’s most significant investments in exploration data on the deep Atlantic margin.
This does not mean that companies already know where the “next Morpho” is.
In fact, it means the opposite.
They are investing precisely because they still don’t know.
The aim of Amapá 3D is to reduce that uncertainty, produce more detailed images of the subsurface, and allow oil companies to determine where it is worth assuming the enormous cost and risk of new drilling.
Moreover, this movement comes at a time when Ibama has authorized new drilling by Petrobras in the region and when the Equatorial Margin is gaining increasing significance in Brazil’s reserve replacement strategy.
Therefore, the next big chapter may not be a new platform.
It could simply be an image.
A three-dimensional image, constructed from millions of seismic signals, capable of indicating where the next geological structure is that justifies placing a probe nearly 3,000 meters over the Atlantic seabed.
And you: after the discovery of hydrocarbons at Morpho, should Brazil accelerate surveys and new drilling in the Equatorial Margin to understand its potential, or maintain a slower pace until environmental and economic risks are better defined?
