In the field of geophysics and wireline logging, an SGA tool (Spectral Gamma Ray) is a device used to measure the natural gamma radiation emitted by rock formations. Unlike standard gamma-ray tools that measure total radiation, spectral tools break down the radiation spectrum to differentiate between potassium, thorium, and uranium. This data is crucial for geologists in identifying specific rock types, clay content, and mineral deposits during oil and gas exploration.

: SGA maintains extensive MOUs with major Korean universities (Hanyang, Kyungdong) and government bodies like Incheon Metropolitan City to foster the "e-sportainment" ecosystem.

: Through its subsidiary, SGA eSPORTS , the academy operates professional gaming teams and provides 1:1 coaching for aspiring pro gamers.
