From Oil Basins to the Lithosphere

Passive-source imaging that delivers low-cost, high-reliability results — from shallow hydrocarbon exploration to full lithospheric structure and metal ore-forming systems.

Oil & Gas · Minerals · Lithosphere

DeepSeis enables passive-source imaging across the full depth spectrum — from shallow hydrocarbon reservoirs to the lithosphere-asthenosphere boundary.

Hydrocarbon Exploration

Oil & Gas Accumulation Patterns

Map sedimentary basin architecture, fault systems, and structural traps using passive-source reflection profiles. DeepSeis images near-surface to upper-crustal structures with high resolution — basement topography, sedimentary interfaces, and shallow fault networks that control hydrocarbon accumulation. A low-cost alternative to active-source surveys for regional exploration.

Depth Range Near-surface → Upper crust (0–15 km)
Target Basement topography, sedimentary interfaces, structural traps
Mode Reflection wave + Surface wave
Advantage Low-cost regional coverage vs. active-source
Case Study Songliao Basin (200+ stations)
Mineral Exploration

Metal Ore-Forming Models

Image deep crustal fault systems and magmatic conduits that control metal mineralization. DeepSeis has been deployed in the Jiaodong Gold Province and Huozaoyun deposit, revealing ore-controlling structures from the upper crust down through the Moho — insights critical for understanding metal ore-forming models at crustal scale.

Depth Range Upper crust → Moho (5–40 km)
Target Ore-controlling faults, magmatic systems, Moho structure
Advantage High-reliability deep structure constraints
Case Study Jiaodong Gold, Huozaoyun Deposit
Lithospheric Imaging

Full Lithosphere Structure

DeepSeis can image the full lithosphere — from the crust through the mantle lithosphere to the lithosphere-asthenosphere boundary (LAB). The same passive-source reflection workflow that maps shallow sedimentary layers can be scaled up to reveal Moho undulations, lithospheric thinning, and subduction-related deformation. This unified approach provides the deep tectonic framework that controls both metal ore-forming and hydrocarbon accumulation patterns.

Depth Range Crust → Mantle lithosphere → LAB (30–200+ km)
Target Moho, LAB, subduction zones, lithospheric thinning
Advantage Low-cost, high-reliability lithospheric constraints
Case Study Mongolia-Okhotsk Suture Zone

Why Passive-Source Reflection?

DeepSeis delivers results comparable to active-source surveys — without the cost, logistics, or environmental impact of explosives and vibrators.

💰 Low Cost

No explosives, vibrators, or marine airguns. Deploy permanent or temporary broadband stations and let ambient noise do the work.

🎯 High Reliability

Continuous recording provides massive data redundancy. AI-assisted QC ensures only high-quality data enters the processing chain.

🌍 Full Depth Coverage

One method, two scales: near-surface imaging (upper crust, 0–15 km) and lithospheric imaging (Moho to LAB, 30–200+ km). The same passive-source reflection workflow covers both.

🔬 Unified Framework

The same workflow serves oil & gas accumulation studies, metal ore-forming research, and lithospheric tectonics.
