Magnus Field case study (pdf 1185.6kb)
Overview
The Magnus field is located 160 km northeast of the Shetland Islands and has been producing since 1983. The reservoir comprises Upper Jurassic sandstones at a depth of approximately 3 km and contains an estimated 1.65 Bbbl of oil, with 795 Mbbl (48%) considered recoverable.
The Q-Marine survey was undertaken as part of an improved oil recovery (IOR) project that involves importing gas from the fields located West of Shetland. The Magnus IOR project is expected to increase recoverable reserves and extend field life by several years. It will also help to reduce gas flaring West of Shetland and at the Sullom Voe terminal.
Enhanced seismic information was needed to help the asset team image smaller faults, define flow barriers, and identify unmapped fault blocks. The highly repeatable seismic data from Q-Marine provided a baseline for planned time-lapse 4D surveys and will allow BP to monitor injected gas movement.
