Marine seismic is how we map the geology beneath the ocean floor. A ship tows a source, usually a set of air guns, behind it, firing bursts of sound down through the water and into the seabed. The echoes that bounce back off rock layers are captured by long cables of hydrophones trailed behind the vessel, and computers turn those echoes into a three-dimensional picture of what lies below. It is the first step in offshore exploration, and it happens long before anyone drills a well.

This is the technology at the center of the “Wildcat” pick in Jim Rickards’s “$150 Trillion Birthright” presentation. Rickards is a former general counsel at Long-Term Capital Management and a best-selling author on currency and geopolitics, and he runs model Press’s Strategic Intelligence letter. His pitch claims President Trump “opened 650 million acres of federal land containing an estimated $150 trillion in buried minerals,” and that three small companies could dominate the discovery technology. Marine seismic is where that story meets reality.

How a Marine Seismic Survey Works

The principle is simple even if the engineering is not. Sound travels through rock at predictable speeds, and different layers reflect it differently. By measuring how long echoes take to return and how strong they are, surveyors can reconstruct the shape of the layers and spot the structures that might trap oil, gas, or other resources. A modern survey vessel can cover hundreds of square kilometers in a single pass, gathering data that is then processed and licensed.

The economics matter more than the physics for investors. A marine seismic company sells data, not drilling results. It gets paid whether or not a client’s well comes in, which is why the business is often called picks-and-shovels for offshore energy — and why the data library itself is the industry’s real product.

The Wildcat and Its Market

The presentation’s “Wildcat” is TGS ASA, the Norwegian energy-data firm formed from the 2023 merger of TGS and PGS, the two leading offshore seismic data companies. TGS ASA collects large seismic data sets and licenses them to oil and gas customers, with a “Deep Sea Minerals Pathfinder” project on the side. The pitch says “The Wildcat controls deep sea detection” and attaches a “1,520% gain potential.”

Since the tease, TGS ASA is the one pick in the green, up 8.9%. The other two names, Geospace Technologies and MIND Technology, are down 73.8% and 56.8% respectively. That is a real, if modest, relative outperformance, and it is worth giving TGS ASA credit for it. We explained the seafloor story in our deep-sea mining explainer and the discovery angle in our AI mineral exploration coverage.

Why Revenue Tracks Oil

The honest read is that marine seismic is an oil and gas business. Revenue rises and falls with energy exploration budgets, and those budgets follow the oil price. TGS ASA and its legacy businesses had their moment during the 2010 to 2012 oil bull market and gave much of it back as the cycle turned. The mining and deep sea minerals part of the business is real but small.

The pitch also leans on an institutional-ownership claim of “only 8%” for one of the picks, implying early entry. Our teardown found the actual figure near 67% for that company. We put the wider market picture in context in our rare earth stocks coverage and our critical minerals strategy explainer.

The Multi-Client Business Model

Most offshore seismic data is sold on a multi-client basis, which shapes the economics and the risk. A survey company shoots a large data set at its own cost, then licenses it to several operators who each pay a fraction of what a proprietary survey would cost. That spreads the cost and lets the vendor sell the same asset repeatedly, so each additional license drops to the bottom line. The tradeoff is that the vendor carries the upfront cost and only recovers it if enough customers license the data. When exploration budgets are healthy, the model is attractive; when they shrink, the data library sits unsold and the company eats the carrying cost. That is the real driver of offshore seismic revenue, and it is tied to oil and gas spending far more than to any mineral discovery. Understanding that model is the honest way to evaluate the “Wildcat” pitch and its “1,520% gain potential,” because the forecast rests on a spending cycle that has not yet turned. The company’s recent single-digit gain, while the only positive among the three, is still a long way from that promise.

What We Genuinely Like

The mechanism is sound. Data vendors and equipment makers get paid on activity, not on outcomes, which is a lower-risk way to play offshore energy than betting on a single discovery. TGS ASA is the clear market leader in offshore seismic data after its merger, and a real rebound in offshore exploration spending would benefit it directly. The offer behind the pitch is The Situation Report at $1,995 per year with no refunds, and the headline forecasts are promotional numbers, not guarantees.
