Operatorship transfer of the Vega oil and gas field
Wintershall has oil and gas exploration and production operations in
Europe, North Africa, South America, Russia, the Caspian Sea region, and the
Middle East. Active for over 80 years, the company recently considerably
expanded activities in Norway through its subsidiary Wintershall Norge.
Wintershall Norge is one of the most successful oil and gas companies on the
Norwegian Continental Shelf (NCS), which has become one of the core regions in
Wintershall's global portfolio.
In March 2015, Wintershall formally took over from Statoil as operator
of the Vega oil and gas field, which became the company's first operated subsea
tie-in field in Norway. It is located in the Norwegian section of the North Sea
and tied back to the Gjøa platform, 28 km to the east. Production of
Vega field started in 2010.
One of the first tasks Wintershall needed to complete in preparation for
its new operatorship was the migration of Statoil's well, seismic, well log,
and interpretation database, into its live Studio E&P knowledge
environment. The imported data needed to be merged with existing Wintershall
information from the Vega field and the result compiled into a unified dataset
before migration to the Studio environment.
Proprietary tools for efficient migration
Schlumberger has developed proprietary tools to provide a simplified
LEAN Six Sigma process for the migration of data into the Studio environment.
The tools help in all three phases of a data migration project: assessment,
design, and implementation. Schlumberger information management professionals
used these tools to quickly and smoothly transition the Vega data. Integrating
all of the Vega data in to the operational Studio environment was completed
within 20 days. The imported data included 51 3D seismic cubes, 15 wells, 892
log curves, 85 3D horizons, 372 faults, and 19 surfaces.
