Q. 12.a of 20 – Volumes at Salftleetby: On the Saltfleeby presentation, you have based your figures on producing an average of 5 mmscf/d (million standard cubic feet per day – 5.5 mmscf/d is for grid entry costs) citing that this was what produced when field last operated 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 given 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 This gives a total for the Year off 29.03 mmscf/d. If you allow for the Field’s 15% annual production curve decline that would become 24.68 mmscf/d. The condensate is also a fraction of the figures in your presentation. Could you confirm which figures are to be believed the official OGA ones or yours?
ANSWER: 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. Since shut-in in 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!
