Serica Energy PLC (AIM:SQZ) Operations Update

London, 5 December 2022 – Serica Energy plc (AIM: SQZ), a British independent upstream oil and gas company with operations centred on the UK North Sea and over 85% gas production, provides the following operations update.

North Eigg

The North Eigg exploration well 3/24c-6B has been drilled to a total depth of 16,728 feet in the Jurassic Heather formation and initial analysis indicates that, whilst the well has encountered hydrocarbons, commercial quantities have not yet been established. At the well location, the objective sands were thinner than had been prognosed but a total of 16 feet of hydrocarbon-bearing sands were encountered, and these have confirmed the presence of hydrocarbons at a deeper depth than in the adjacent producing Rhum field.

A full suite of wireline logging data has been acquired and our analysis is ongoing. We aim to determine if a future sidetrack location can be designed to better evaluate the volumes of hydrocarbon in this new discovery. It is our intention that the well will be suspended pending the results of this further work prior to future potential re-entry and sidetrack.

Final well costs will not be known until after the rig is off hire, but it is likely that the net after tax cost of the well to Serica will be around £13 million.

Production

Serica production performance in the second half of 2022 continues to benefit from the investment programmes that the company has continually undertaken since the acquisition of interests in Bruce, Keith and Rhum in 2018. Serica’s net production is as follows:

Serica’s net production YTD has averaged 25,955 boe/d and full year 2022 production is expected to be within the existing guidance range of 26,000 to 28,000 boe/d. Serica’s production continues to be more than 85% gas.

Commodity Prices and Hedging

Commodity prices, particularly gas, have remained strong during the second half of 2022 although somewhat lower in October and November. Monthly average market prices have been as follows:

1 Bruce and Rhum production figures were impacted by the planned 14-day preventative maintenance

shutdown in late July and early August

2 Columbus and Erskine field production was also impacted by planned maintenance shutdowns

Due to Serica’s increasing financial strength, the company has not entered into any new gas price hedging since July 2021 and has no immediate plans to do so. Serica continues to hold a modest remaining hedging programme with less than 20% of gas production covered in the second half of 2022, thereby allowing the company to benefit from full market prices on over 80% of its production. The existing gas hedges will reduce to zero during the next twelve months.

At the start of this year Serica held hedges covering a total of 146 million therms3. This number will have dropped to below 32 million therms by the end of 2022. Margin call requirements on these hedges had stood at over £300 million earlier in the year but have now reduced to significantly below £100 million.

Forward Programme

Serica continues to provide responsibly sourced gas to the UK domestic market, protecting security of supply, and reducing reliance on higher carbon intensity imports as part of the transition to a lower carbon future. We will continue to invest in our assets to maintain production levels and provide jobs.

The recent action by the UK Government to increase the marginal rate of tax on the UK Upstream Oil & Gas sector to 75% with no floor to prices, will make it challenging for the industry to invest in new longer-term UKCS projects. Nevertheless, we remain committed to expanding our portfolio through M&A.

Mitch Flegg, Chief Executive of Serica Energy, commented:

” Although the North Eigg exploration well has not delivered the result we had hoped for, it has demonstrated the presence of hydrocarbons and provided a huge amount of high-quality data. In particular, the presence of hydrocarbons at deeper than expected depths will lead to a re-evaluation of both North Eigg and South Eigg.

Elsewhere, our production performance has been strong, and we will continue to invest in our existing portfolio in order to maintain this performance. In parallel, as a significant North Sea operator, Serica will continue to selectively review new potential projects to maintain our North Sea presence whilst also seeking greater clarity and stability on the taxation regime to enable these projects to proceed.

While we believe in the importance of the UK Oil & Gas sector, we are now considering opportunities in other countries alongside those in the UK as we continue to seek to expand our portfolio and create value for all of our stakeholders .”
