TGS Nopec, the company most investors know today simply as TGS ASA (TGSGY), is a Norwegian seismic data firm listed on the Oslo stock exchange, with an American depositary receipt that trades over the counter. Its name carries a hint of its history, “Nopec” once stood for Norwegian Petroleum Consultants, but the business today is defined by the 2023 merger of TGS and PGS that created one of the largest offshore seismic data companies in the world.

The company shows up in Jim Rickards’s “$150 Trillion Birthright” presentation as “The Wildcat,” the pick the pitch says “controls deep sea detection” with “1,520% gain potential.” Rickards, a former general counsel at Long-Term Capital Management, best-selling author, and editor of model Press’s Strategic Intelligence letter, folds TGS into a claim that President Trump “opened 650 million acres of federal land containing an estimated $150 trillion in buried minerals.” The honest read starts with what the company actually sells.

The Data Licensing Model

TGS is first and foremost a data business. It shoots and processes offshore seismic surveys, then licenses the resulting data to oil and gas companies, sometimes to many customers at once. Once a survey is acquired, the data lives on the company’s servers and can be sold repeatedly, which makes the library a durable asset with low marginal costs.

This model is the reason TGS is often considered the purest public play on seismic data. It carries far less risk than a driller, because it does not spend on wells and does not eat dry holes. Its downside is a slow order book when energy companies cut exploration budgets, which is exactly what happens when oil prices fall.

The Deep Sea Connection

The Birthright pitch leans on a side project TGS calls the “Deep Sea Minerals Pathfinder.” The concept is that the same acoustic techniques used to map oil and gas can locate and map polymetallic nodule fields on the seafloor. That is a real technical overlap, and it is the most direct tie between TGS and the seabed-mining theme in the presentation.

For now, though, the project is a small part of the business. Offshore seismic data licensing for oil and gas customers remains the core. Our deep-sea mining explainer covers the nodule harvest and its timeline, and it is worth reading alongside any claim that TGS is a pure mining play.

Where the Pitch Stretches

The presentation groups TGS with two other “MDP” companies, mineral-discovery-technology plays. “The Pioneer” is Geospace Technologies, a maker of land and marine seismic equipment, and “The Innovator” is MIND Technology, which builds offshore seismic hardware under the Seamap brand. All three are oil and gas seismic companies whose revenue tracks energy exploration budgets and the oil price, not mineral discovery.

Our teardown of the presentation found that the mineral framing overstates how much of these companies’ revenue is tied to mining, and that the ad’s claim about a $2 billion to $100 billion market “explosion” over twelve months does not match how federal leasing actually grows.

The Scoreboard and the Valuation

The June 24, 2025 catalyst tied to unlocking Phase II came and went with no surge. Since the tease, TGS is up 8.9%, the only one of the three picks in positive territory, while Geospace Technologies is down 73.8% and MIND Technology down 56.8%. A single-digit gain is a real result, but it sits far from the promised “1,520% gain potential.”

TGS is a legitimate, established company with a durable data library and a genuine, if early, deep-sea angle. For the broader critical minerals context, our critical minerals strategy explainer and our rare earth stocks coverage separate the real policy push from the promotional packaging.

The offer behind the pitch is the Situation Report at $1,995 per year with no refunds. The case for TGS should rest on rising offshore exploration spending and the long-term deep-sea story, not on a promotional deadline.

The “Nopec” in the name is a piece of history. It once stood for Norwegian Petroleum Consultants, a reminder that the firm grew out of the Norwegian oil services cluster before it became a global seismic data company. The American depositary receipt trades over the counter, which means US investors buy a wrapper for the Oslo-listed shares rather than the ordinary shares directly, and liquidity can be thinner than on a major US exchange. None of that changes what the company is, a serious offshore seismic data business. It does mean the practical mechanics of buying it deserve a moment of attention before any trade is placed.

For US investors, the over-the-counter listing also means TGS reports its financials under Norwegian accounting and follows a foreign reporting calendar, a minor but real difference from a domestic US company. None of that is a reason to avoid the stock, and none of it changes the core business. It is simply the practical texture of owning an Oslo-listed data company through an American depositary receipt.
