Subsurface Engineering

We realise the engineering and supervision of underground services on the basis of geological investigations, technical circumstances and customer requirements. Such services include carrying out the drilling, the leaching of caverns, the completion of drillings and storage wells, cased hole measurements and running in of welded tubing and casing. We also design subsurface equipment for special kinds of application.

Our services include:

  • Planning of drillings, workover services, re-entries and repairs
  • Completions
  • Well interventions
  • Planning of snubbing and coiled tubing work
  • Backfilling of wells
  • Leaching, flooding and first gas injection of caverns
  • 3D leaching simulation with high-performance software
  • Solution mining under gas
  • Casing inspections, borehole measurements
  • Technical assessments
  • Lifecycle analyses for storage facilities
  • Running-in of welded tubing and casings
  • Working with authorities
  • Construction supervision
  • Design of subsurface equipment
  • Working on research and development issues
