All communication to the reservoir is via the near wellbore and hence is influenced by near-wellbore effects – this should be understood and mitigated from being the weak link in production/injection.

Elfen wellbore encompasses all near wellbore applications such as; stress, stability and loss circulation, fines migration and mud-cake modelling, sanding analysis and prediction, sand screens and advanced completions systems design, near wellbore fracture and damage prediction. Also includes well string assessments captured from Elfen horizon output

  • Well-life modelling of all near wellbore processes
  • Completion system and well string assessments
  • Injection and depletion induced permeability damaged
  • Thermal-Hydro-Mechanical coupling

Modelling Capabilities
