Case Study
VisiTrak service ensured optimal well placement
VisiTrak service ensured optimal well placement Challenges • First oil-producing field in the Barents Sea • Complex structural environment • Wellbore trajectory restricted to 1.5° dogleg severity Results • Gathered all measurements in real time using LWD services • Provided all interpretations in 3D environment • Mapped reservoir boundaries within 98 ft of the wellbore • Drilled 3,281 ft with average ROP of 92 ft/hr • Provided real-time inversion answers The Goliat field, operated by Eni Norge AS, has two separate sandstone reservoirs planned for development—the late Triassic/Jurassic Realgrunnen subgroup at approximately 3,609 ft (1,100 m) mean sea level (MSL), and the Middle Triassic Kobbe formation at approximate 5,906 ft (1,800 m) MSL. The Goliat field is the first oil-p
