Tellus Geo-Consulting has been a leading force in processing MASW data for projects across the Middle East since 2017. Specializing in MASW Seismic Data Processing, we leverage the capabilities of our customized software to unveil profound insights beneath the Earth's surface.
Based at our processing centre in London, our expert team employs a meticulous approach, ensuring unparalleled accuracy and reliability for your projects.
Reliability
Proudly standing as the fastest solution in the market, our software not only guarantees exceptional results but also enhances cash flow for our clients. Our revolutionary techniques guarantee reliable and repeatable data processing, effectively eliminating human error.
Detailed
With proficiency in contouring software, we meticulously craft detailed velocity distribution images, offering a visual representation of subsurface velocity variations. These images play a pivotal role in interpreting geological structures and optimizing engineering strategies.
Insightful
Tellus delivers precise and insightful analysis, empowering your decision making process in engineering geophysics giving you confidence through our tailored services.
How We Deliver
Utilize Tellus to remotely process your MASW data and:
• Reduce company overheads significantly.
• Eliminate the need and expense for multiple dedicated data processing personnel.
• Produce faster, reliable, and repeatable results.
• Generate comprehensive engineering outputs according to Eurocode 8 or NERPH.
• Enhance operational efficiency.
We have successfully processed data for numerous prestigious projects, including:
• Red Line South, Doha Metro, Qatar
• Capital District, UAE
• MEWA Dams Project, KSA
• The Line, Neom Project, KSA
QA/QC Workflow
In conducting a QC of a contractors project, both in the field and in office processing the following is assessed:
FIELDWORK
-
Energy source type
-
Array length
-
Number of geophones
-
Distance between geophones
-
Source – receiver offset distance
-
Reading spacing
-
Data stacking regime (if any)
-
Record length
-
Sample interval (Nyquist conformation)
-
Georeferencing / survey positioning regime
-
Accurate field survey notes
All the above must be conducted in a regular and consistent manner within a survey.
It is not acceptable practice to change settings during a survey line (data sampling, record length, number of geophones, move-up distances etc).
DATA PROCESSING
After initial QA/QC of raw data, as detailed above, the data will be processed as follows:
1) Latest data processing software
- correct geometry & topography encoding
- consistent dispersion curve picking
2) Display software
- normalised data ranges for all outputs
- finished velocity plots provided in .srf and .pdf formats
Report will be in Word or PDF format and Include:
-
Representative Photos from each site surveyed (if provided by client)
-
QC results from data analysis
-
Bedrock profile based on rock having a seismic shear velocity of 950m/s and above
-
Confidence plot for comparison between QC results and Bedrock image
-
Vs30 seismic site characterisation
-
Full scale Vs distribution plot
-
Shear modulus plot
-
Poisson’s ratio plot
-
Young’s modulus plot
-
Average Vs Graph
-
Average Vp Graph
-
Average Shear Modulus Graph
-
Average Poisson’s Graph
-
Average Young’s Modulus graph
