BUDE, UK – WGP has announced the successful completion of the 13th life-of-field seismic (LoFS) survey over the Valhall field in the North Sea.
BP Norge AS and operating partner Hess Norge AS, contracted WGP to provide the source sub-arrays necessary to maintain the repeatability required for a permanent reservoir monitoring project. With the trenching of 120 km (75 mi) of ocean bottom cable, Valhall LoFS began in 2003 with an average of two surveys performed per year.
WGP installed Thalassa Energy Services’ containerized seismic source system onto the PSV Stril Myster during a six-day mobilization period in Stavanger. The company says that Thalassa’s source system is the same design as used on all of the LoFS surveys since the project’s inception, and thus affords the required level of source repeatability.
