Na północno-wschodnim wybrzeżu Szkocji, w miejscowości Portgordon zostały wykonane cztery równoległe wyjścia w morze w technologii horyzontalnych przewiertów sterowanych HDD. Długość każdego przewiertu wyniosła ponad 1600 m. Dla zmniejszenia otworowego współczynnika tarcia i w celu obniżenia momentu obrotowego na przewodzie wiertniczym zastosowano specjalne rozwiązanie w zakresie systemu płuczkowego
