BRACKNELL, UK -- Trelleborg CRP has developed the CFW+, a new HP/HT crushable foam wrap incorporating glass bubbles from 3M. CFW+ provides an enhanced solution for the mitigation of subsea well casing failure due to annular pressure build-up, or trapped annular pressure.
"Until now, the operating range of our crushable foam wrap (CFW) solution has had typical performance in excess of 4000 psi 60-80º C (140-176° F), which has been sufficient to meet the needs of such projects as the 21 well installation we have just completed offshore Nigeria," says Guy Downie, manager subsea group, Trelleborg.
"However, due to trends in drilling more complex wells, sometimes much deeper and further offshore, we have developed CFW+ which can provide an APB solution for these more demanding situations to temperatures in excess of 110º C (230° F) and much greater pressures."
