Technology

Pressure VES Seal Tool

  • Predict column heights from lithology, T&P,  capillary and mechanical sealing capacity. 
  • Database of over 50 published fields provides analogue trends to compare with Lithology dependent rock property trends.  
  • Compare your fields and prospects to the Database - or we can build your own.
