Offshore exploration without the vessel.

Remote offshore subsurface mapping through up to 15,000 ft of combined water column and rock — no ships, no airguns, no marine-life impact, no long permitting windows. Confirm prospectivity before you charter a single day of rig time.

The problem

Offshore is where dry holes hurt most.

A single deepwater exploration well can cost $75M–$150M. Marine seismic programs add tens of millions more, with acquisition windows constrained by weather, permitting, and mammal-protection rules.

Inside Earth maps offshore prospects remotely — through the water column, through the overburden — returning hydrocarbon confirmation, indicated volume, and depth on the same grid you use for seismic interpretation.

The commercial implication is blunt: fewer dry wells, smaller seismic footprints, compressed cycle time, and a materially smaller environmental signature in marine-sensitive basins.

What we deliver

Offshore prospectivity, screen-ready.

Whether you're ranking blocks pre-license or narrowing targets within a concession, our deliverables are formatted for the tools your subsurface team already uses.

Sea-to-seabed screen

Pre-license screening of entire offshore blocks. Confirm hydrocarbon presence before you bid, farm in, or commit to a full seismic program.

Seismic acquisition planning

Use our mapping to focus seismic lines where they add the most value — compressing vessel days and cost of acquisition.

Ambiguous-data rescue

Where legacy offshore seismic is noisy or inconclusive, we overlay hydrocarbon signatures to convert "maybe" into a high-confidence decision.

Use cases

Where offshore operators deploy us.

License round evaluation

Independently verify a government data room before you submit a bid — avoid acreage you can't substantiate.

Deepwater target ranking

Rank prospects within a license block before committing drilling capital — and plan drilling order by indicated volume.

ESG-sensitive basins

In marine-protected areas and whale-migration corridors, a zero-airgun alternative is increasingly the only acceptable approach.

Mature-basin infill

Identify bypassed compartments in producing offshore fields — extend field life with targeted subsea tie-backs.

FAQ

Questions engineers and exploration VPs ask us.

Short answers. If something here touches your project, ask us the specific version under NDA.

Does water depth affect the survey or reduce the effective subsurface penetration?

Our 15,000-foot maximum mapping depth is the combined water column plus rock penetration. For a 3,000-foot water depth, we can still resolve targets up to 12,000 feet below the seabed. For ultra-deepwater cases (>5,000 ft water), effective sub-seabed penetration reduces proportionally — we'll advise in scoping whether your target is reachable.

How does your offshore survey compare to marine 3D seismic on cost and timeline?

A standard marine 3D acquisition plus processing cycle runs into tens of millions of dollars and many months of vessel time plus interpretation. Our offshore surveys are typically delivered in 6–10 weeks with no vessel mobilization, no airguns, no weather windows, and no marine-mammal permitting. Where we co-exist with seismic, operators typically use us to focus the seismic program — 3× reduction in required acquisition days is common.

Can your method be used in marine-protected areas or near whale migration corridors?

Yes — this is one of the fastest-growing offshore use cases. We produce no acoustic emissions, no vessel disturbance, and no seabed contact. In basins where airgun seismic is effectively blocked by environmental rules, remote subsurface mapping is often the only option to progress a prospect.

What's the typical confidence level on offshore hydrocarbon detection vs. onshore?

Slightly lower than the best onshore engagements, primarily because the water column adds signal attenuation. We address this by calibrating against any available legacy wells, seismic, or drilling outcomes in the region. Confidence scores ship per polygon in every deliverable.

Is the output suitable for presenting to licensing authorities or partner JVs?

Yes. Our deliverables are commonly included in partnership data rooms, farm-in packages, and license-round submissions as supporting material. We're happy to produce both an operator-facing technical report and a partner-ready executive summary.

Can you screen an entire open offshore license block pre-bid, within a tender window?

Yes. Short-turnaround block screens — typically 5–7 weeks — are our most common license-round use case. Send us the block coordinates and the bid deadline; we'll confirm feasibility and pricing within one business day.
