Projektowane w ostatnich latach coraz dłuższe odcinki podziemnych rurociągów, transportujących różnego rodzaju media, mobilizują branżę HDD do szukania nowych technologicznych rozwiązań. Płuczka wiertnicza, stosowana dotychczas przy wierceniach długodystansowych (powyżej 3000 m) HDD, jest już jednak niewystarczająca i również wymaga technologicznej innowacji. Podobnie było w przypadku realizacji rekordowego przewiertu HDD o długości 4608 m na terenie ekosystemu Marsdiep (Holandia)
