The main aims of the column experiments are:

  • To obtain larger scale (decimetre scale) 2-phase flow properties for host rock and EBS materials
  • To assess the concept of and quantify the gas entry pressure of sand/bentonite (S/B) mixtures
  • To visualise gas and water flow in S/B mixtures
  • To demonstrate the functioning of gas permeable plugs and seals on a decimetre scale
  • To provide experimental evidence of cement-EBS interaction under realistic boundary conditions
