Overview
Wellesley took over operatorship of the Grosbeak discovery and drilled two successful appraisal wells in 2018, confirming significant volumes of oil and gas in Brent and Sognefjord reservoirs. The field is now fully appraised with 6 well penetrations and a large dataset including 2 DSTs, 677m of core, logs and PSDM seismic. The appraisal campaign found multi-Darcy reservoirs with good horizontal connectivity, 44° API oil and low CO2 gas.

DEVELOPMENT TIMELINE
In 2021, Wellesley completed a swap transaction to transfer operatorship to Equinor, aligning operatorship with the other FANTA development projects and with the Troll host infrastructure. Grosbeak is expected to be developed as part of the FANTA project, with 3 oil producers, 3 water injectors and up to 2 gas producers.
