Guillemot West and Guillemot Northwest are a cluster of small oil and gas developments to be developed as subsea tiebacks to the Triton FPSO (operated by Amerada Hess) located 13km southwest of the Guillemot West field area. Shell will act as operator through the primary field development phase; Veba became field operator at first oil in April 2000.
