About the field
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
- Development
- Tyrving is a field in the central North Sea, 20 kilometres east of the Alvheim field. Tyrving consists of three discoveries: Trine, Trell and Trell North. The water depth is 120 metres. The plan for development and operation (PDO) was approved in 2023. The development concept includes three production wells, one in each discovery, tied to the Alvheim production, storage and offloading vessel (FPSO). The production started in 2024.
- Reservoir
- The reservoirs contain oil in sandstone of Paleocene age in the Heimdal Formation, at depths of 2140 and 2180 metres. The reservoir properties are excellent.
- Recovery strategy
- The drainage strategy is pressure depletion with aquifer support.
- Transport
- The well stream is routed by pipeline to the Alvheim FPSO, where the oil is offloaded to shuttle tankers. The gas is transported by pipeline from Alvheim to the Scottish Area Gas Evacuation (SAGE) pipeline in the UK sector.
- Status
- The field has produced higher than expected, mainly due to delayed water cut.
