Laboratory of Applied Geophysics

Director: Sofia Stamataki

Website:

The laboratory was established on 12 June 1992 (PD 207 FEK 98/12-6-92) and it is in the premises of the Sector Mining Engineering of  the School of Mining and Metallurgical Engineering, National Technical University. The Lab facilities occupy 150 m2 covered area on the 2nd floor of the School building in Polytechnioupoli Zografou.  The year 2000 it has been incorporated with the unit of Drilling Technology and Petroleum Engineering. The main purpose of the Laboratory is to serve the educational and research needs in the scientific field of geophysical surveys and drilling for subsurface investigation and research / exploitation of hydrocarbons. The mission of the Laboratory is:

The provision of educational work to undergraduate and postgraduate students of NTUA to grow skills with the effective use of science and technology in the field of Laboratory. To conduct basic and applied research, autonomously or under-funded research programs in helping to solve problems of mining and geotechnical sector and oil industry, in the development and use of modern technologies and computational tools.  It provides services to third parties in the form of field measurements, analysis, processing and interpretation of results, giving technical reports.  The latter two activities are governed by the Rules of the Management Committee of the Special Account for Research of the  University.  The equipment and expertise available allows the Lab to operate in the following areas:

A. Surface Applied Geophysics
Field measurements, analysis, processing and interpretation of data with the application of geophysical methods such as gravity and magnetic methods, seismic refraction, electrical methods (soundings, profiling and electrical tomography), electromagnetics (conductivity measurement, ground penetrating radar), which have applications in the fields below:

  1. Mining Research:
    • Identification and spatial assessment of mineral zones using geophysical methods
    • Design of drilling surveys, standards in sample drilling, evaluating core samples
  2. Subsurface Structure, and Construction Projects:
    • Stratigraphic mapping of subsurface
    • Detection of the bedrock relief, slopes and folds of sedimentary formations
    • Detection and qualitative assessment of zones with different geotechnical characteristics in the underground (fault zones, tectonism, loose zones)
    • Detection and characteristics of underground openings (underground openings-cavities, tunnels, abandoned mining facilities, pipelines, tanks).
    • Definition of semi-homogeneous underground blocks.
    • Detection of the thickness of sediments or weathered layers
    • Evaluation of the mechanical parameters of the rock mass (Young modulus, Poisson ratio),
    • Fine detection  of the road deposits,
    • Fine detection of  metal reinforcement of building components
  3. Hydrogeology and Environment:
    • Identify aquifer / water resources assessment (depth and extend of permeable - or not formations of the underground)
    • Managing water resources (underground flows, groundwater enrichment - cases of low dams or reservoirs)
    • Quality / protection of water resources (groundwater pollution due to salinization, continuation of permeable zones with areas of pollution)
    • Identify areas of leakage in cases of dams
    • Detection of the size, limits and volumes of waste
    • Assessment of sites for landfill and waste disposal
    • Geothermal Research (identify geothermal fields)
  4. Archaeological survey (detection of buried structures of archaeological interest)

B. Geophysical prospection in boreholes (Borehole loggings)
Well logging in drilling of 300 feet depth, measuring natural gamma radiation, density, temperature, conductivity, resistance, single point resistance and self potential.  There is software for management, processing and recording data. Continuous recording of these parameters within the borehole enables identification of key properties (physical and mechanical) of formations in situ.

C. Unit of Drilling Technology
The Lab has a pilot rotary drilling rig for shallow vertical or inclined drilling and continuous sampling.  It includes all the mechanisms and parts of a typical drilling system.  In the scientific field of drilling technology, research and teaching focuses on the following:
o Design of deep drillings
o Assessment and control of drilling data
o Environmental drilling waste management operations

D. Unit of Hydrocarbon Exploitation
The Lab offers powerful computing base and specialized software with the help of which can respond to needs such as:

  • Evaluation / analysis of underground reservoirs
  • Simulation of thermodynamic behaviour of reservoir fluids 
  • Reservoir Engineering (reservoir simulation)
  • Underground storage of natural gas in exploited oil or gas fields
  • CO2 storage in depleted gas fields and/or oil fields with EOR
