RE: Saltfleetby Production reported in Dec 201719 Jun 2022 20:57
12.a On the Saltfleeby presentation, you have based your figures on producing 5 mmscf/d (million standard cubic feet per day or 50,750 therms/day – the figure of 5.5 mmscf/d referred to transportation charging) citing that this was what produced when field last produced in December 2017. Could you please explain where this figure has come from? The OGA Official figures for Saltfleetby are as follows and are in mmscf/d (taken as averages for each month) Jan 4.55 Feb 5.08 March 4.39 April 3.46 May 4.86 June 1.53 July 2.97 Aug 0.56 Sep 0.00 Oct 0.00 Nov 1.19 Dec 0.44 – giving an average daily production across the year of 2.5 mmscf/d. If you allow for your 15% fall yearly that would become just over 2 mmscf/d. The condensate is also a fraction of your figures.

Both figures are entirely to be believed. Production at Saltfleetby shut down in December 2017 some several months before Theddlethorpe terminal formally shut down. However through most of 2017 the main compressor at Theddlethorpe, which was newly installed, suffered teething problems which eventually resulted in it being taken off line in August. When it was restarted in November, production was self-limited whilst the machinery was undergoing testing. The problems with the compressor were well known to the many staff and contractors who worked there or supplied gas there. Saltfleetby well deliverability, or the measured combined capacity of the two producing wells to flow, exceeded 5 mmscf/d throughout 2017. That’s to say the wells produced 5 mmscf/d on the days they could actually be operated and the compressor was functional. Since the Field was shut-in at the end of 2017, the reservoir pressure has equalised by a significant amount and locally increased, so the actual deliverability now will exceed 5 mmscf/d. The condensate production forecast is based on the average condensate gas ratio for the year preceding the shut down. We will have our own compressor on-site at Saltfleetby going forward!
