Offer

Epslog SA sells or leases custom-made Wombats that can be built to satisfy your particular needs. In addition we provide training to designated personnel.

Moreover, Epslog offers laboratory and/or field testing of materials using the "scratch test" technique and its state-of-the-art portable equipments. This direct and rapid mean to obtain logs of in situ strength has important applications in different industries.

 

Applications

  • Petroleum industry:
    • Wellbore stability
    • Sanding predictions
    • Enhance reservoir characterization
  • C02 sequestration: influence on cement exposure
  • Civil engineering: for the early detection of damage (chemical, mechanical) or fatigue in structures; and for quality control of the manufacturing of construction materials (cement, bricks, concrete, mortar...)
  • Mining: rock properties characterization (strength and abrasiveness), recommandation in drilling operations, excavation and design of tools.
  • Dredging: Quick onsite determination of rock properties of rough dredged rocks, recommendation and design of cutting tools.
  • Special applications: detection of thermal effects on refractory bricks; anisotropy of natural or man-made materials
