Strataimage Energy Services

Strataimage Consultoria Ltda was founded in 2003 in Rio de Janeiro, Brazil, and is managed by Patricia de Lugão and Berthold Kriegshäuser. In 2021, we established a sister company in Charlotte, North Carolina, USA, Strataimage Energy Services, Inc, to provide the same high-quality data and services that we have been providing in Brazil.

Our services

Strataimage is a geophysical acquisition company specialized in onshore electromagnetic, magnetotelluric (AMT/MT) and time domain electromagnetic (TDEM) methods. We also offer services using potential methods such as gravimetry, magnetometry (both ground and UAV-based) and gamma spectrometry, in addition to integration with the seismic method and geological interpretation.

Strataimage has carried out several projects related to oil and gas exploration, mining, geothermal, and engineering. For more information, please refer to the Multiclient Map.

Magnetics (Ground and UAV-Based)

The magnetic method is one of the oldest and widely used geophysical exploration techniques. Magnetometry is used to measure variations in the Earth's magnetic field, which can be influenced by ferromagnetic minerals in the subsurface. Magnetic surveys are one of the most reliable methods to rapidly survey a large area for structures. It includes both ground-based and UAV-based (Unmanned Aerial Vehicle) surveys, the latter providing a broader area coverage and access to challenging terrains.

Magnetotelluric (AMT/MT)

MT and AMT techniques measure natural electromagnetic fields at the Earth's surface to study the Earth's subsurface electrical conductivity. These methods are effective in exploring geothermal resources, hydrocarbons, and mineral deposits, especially at great depths.

Onshore Near-Surface Electromagnetics (EM)

Onshore Near-Surface Electromagnetic (EM) methods typically operate in time- or frequency-domain. A changing transmitter current induces secondary currents in the subsurface that yield information about the resistivity distribution at depth. It has agricultural applications detecting variations in soil composition, water content, and the presence of nutrients.

Gravimetry

This technique measures variations in the Earth's gravitational field caused by the density differences in underlying rocks and minerals. Gravimetry can reveal geological structures like caverns, faults, or mineral deposits.

Time-Domain Electromagnetics (TDEM)

TDEM involves transmitting a brief, powerful electromagnetic pulse into the ground and measuring the response. It is routinely used in mineral and groundwater exploration.

Gamma Spectometry

Gamma-ray spectrometry is a useful geophysical method that can be surveyed both ground-based and/or UAV-based. It is a quick and nondestructive survey technique that can be used to identify various radioactive isotopes in the subsurface to identify different rock types.
