RE: First gas should be Monday according to guidance15 Jan 2023 17:55
As SpArmada pointed out flaring occurred on 8th and 11th January and, even when the extended well test has finished, there are final steps to implement before first gas. The current strong winds around the platform may have led to testing taking a little longer than expected in the past few days. I won't be disappointed if first gas is announced, when they are ready, later in the week.
The image from Copernicus supplied by SpArmada shows a lot of detail. The circular helipad is adjacent to the Southerly leg of the rig, and the two Northerly legs are visible.
Whilst drilling the well, the rig would be positioned over the top of the Southwark platform. I'm assuming that the rig is still in this position whilst the testing is done. In that case the blur to the North of the rig is the platform. The red flare would be coming from the rig.
