LONDON – The jackup Noble Hans Deul reached the 500 m (1,6,400 ft) zone on IOG plc’s Southwark platform in the southern North Sea in the United Kingdom, following repairs to one of the legs of the platform. form.
Development drilling at Saturn fell two months behind schedule after rig had to be pulled from the station, but first gas is now expected to follow by mid-2022, following installation slated for Q1. of the 3.7 mi (6 km) Saturn Banks pipeline. platform extension.
Subsequently, the rig will be transferred to drill the Goddard and Kelham North / Central appraisal wells, with IOG evaluating reservoir and production data from Southwark 1 and 2 wells in order to optimize the well design of Southwark 3.
At the Bacton gas receiving terminal on the Norfolk coast in eastern England, the company is working with terminal operator Perenco (UK) and contractors on site to complete the remaining return to service required to commission gas from its Saturn Banks Phase 1 project.
A new 45 m (147 ft) emergency vent stack is in place, electrical and instrumentation activities are underway, and power-up and testing of the shore-based systems is expected to begin shortly.
The final stages of the first gas include commissioning the control and communication systems and degassing the pipeline system prior to the opening of the Blythe and Elgood wells.
As for Phase 2 of Saturn Banks, IOG plans to submit its schedule for selecting the concept and sanctioning the development of Nailsworth to the UK Oil and Gas Authority this month.
Nailsworth, 19 km (11.8 mi) northwest of the Southwark field in 25-40 m (82-131 ft) of water, will likely be the first Phase 2 field to be developed. The company is developing new static and dynamic subsurface models based on reprocessed 3D seismic to refine its estimate of recoverable gas.
Nailsworth gas production is expected to be exported through the Southwark platform and the Saturn Banks pipeline system.
More 3D seismic is being reprocessed on the P2589 license to pre-stack the deep migration in order to reassess the extent of the Panther and Grafton discoveries.
