WGP wins BP Life of Field Seismic project at Valhall

Sources: WGP, BP

WGP has completed the mobilization of the M/V Stril Myster and started operations to provide the high quality shot survey for BP's Valhall Life of Field Seismic (LoFS) project. 

In 2003 BP installed its LoFS Ocean Bottom Cable (OBC) array and contracted WGP to design the source system. Eight years and 11 repeat surveys later, WGP has been contracted to install and operate the same Portable Source System, now owned and contracted by Thalassa Energy Services Ltd (TESL) to continue to provide the precisely positioned source sub-arrays necessary to acquire survey data to the highest technical standards with the unmatched repeatability required to maintain and expand upon the quality of the Valhall LoFS 4D database. 

The Valhall LoFS shooting area consists of 179 shot lines spaced 50m apart with an average shot-line length of 14.2km, over 13 permanently installed and trenched receiver lines of GERI OBC. The total number of pre-plot shots in the survey area is 51,041. 

WGP was awarded the 3.5 year, 7 repeat surveys, contract after providing a competitive bid and scoring highly in a rigorous BP HSSE audit." 


Discovered in 1969 and coming on-stream in 1982, Valhall is under steady development and is expected to produce until 2050. A new high tech production and hotel platform will be installed in 2010. Located in 70 meters of water offshore Norway, the Valhall complex consists today of five separate steel platforms for quarters, drilling, wellheads, production and water injection respectively.
