FEG conducted a 3D underground utility scanning survey for SAMSUNG at Jubail Industrial City; the goal of the survey was to produce depth, type, size, and invert levels of several underground service lines for clash analysis prior to further construction and re-routing planning. For the end user's convenience, the survey results were presented in 12D and AutoCAD 3D software.
We surveyed three sites, Ras-Alkhair, KAEC, and Yanbu, using multi-method geophysical exploration and wireline logging for the above-mentioned project. MASW and ERT surveys were used for cavity investigation, as well as Televiewer Imagery, Spectral Gamma, flowmeter logging, and seismic downhole for rock characterization.
FEG carried pout Multi-channal analysis of Surface Waves (MASW) survey was carried out for National Guard Site in Damam region to investigate for underground cavities. Worley was the project consultant. The survey revealed thickness of alluvial deposit, depth to hard-rock and underground cavities.
As part of a major development program, we conducted several seismic downhole ASTM D7400 surveys for soil and rock characterization for Saudi Downtown. The surveys were conducted in the Hail and Tabuk regions. The project also includes rock fall studies, high resolution aerial imagery and a digital elevation model created with a UAV, as well as marine surveys using a sub-bottom profiler, bathymetry, and an echo sounder.
FEG is currently conducting multiple wireline surveys for Trojena, a NEOM project. PS logging, Acoustic TV and Gamm-Gamma density, and Seismic Crosshole ASTM D4428 were all part of the surveys. The surveys provide critical information for the site's geotechnical characterization over difficult and mountainous terrain.
FEG performed multi-method geophysical exploration and wireline logging for Onshore Geotechnical Investigation for ACMC KSA Supercenter Phase-1(VC TO VO) FEL3. The project included MASW and VS30 for soil characterization.
