Description of the Majorca site

 

 

The Majorca site (12,000 m2) is located at Ses Sitjoles, in the south-east of the island. It offers an aquifer in a Miocene reefal limestone setting, highly permeable, with a number of meter-scale karstic cavities. Intensive farming and irrigation in this area have led to over-exploitation of the water, which has caused salt water intrusion up to 15 km from the coast, resulting in chloride groundwater pollution. The experimental site includes a network of twelve boreholes of 100 m depth, with six fully cored. The site is monitored by a team from UMR Géosciences Montpellier for:

  • In situ characterization using borehole-measurement campaigns: geological structure intersected (walls imagery); petrophysical characterization (electrical, acoustic, natural radioactivity); and flows characterization using hydro-geophysical methods (discharge, self-potential, hydro-dispersive behaviour, etc.).
  • Petrophysical and x-ray tomographic characterization of cores
  • Continuous reservoir monitoring using new geophysical observation techniques (igeo-SER) for periodic measurements (hourly or daily) of variables such as electrical resistivity and electrokinetic potential, pressure and temperature, and ionic load of fluids.
  • Regular sampling and analysis of fluids.
  • Data analysis to evaluate the reservoir’s response to external stresses both natural (climatic, tectonic, etc.) and induced, for instance during experimentation (tracer injection, pumping).
  • Simulation and modelling of transport processes within the reservoir.

The team is also working on a experimental site Lavalette near from Montpellier.  

 

Data Available At The Majorca Site

 

Access to the data from Google Earth module

The Google Earth module provides a site visualization and information on data available such as types of measurements, locations, dates, etc. This interface also provides an overview of geophysical maps and cross-sections, which can be directly downloaded from the available links. Data available through predefined requests can be downloaded from this interface too.
