2 Agenda Welcome & Decarbonised Fuels 1 (DF1) Introduction General Miller overview & history DF1 strategy overview and design Hydrogen Power Generation details Offshore scope overview

3 Miller Platform Overview First post-piper Alpha facility in UK Commenced production 1992 $1.3bn project 55,000Te structure Plateau production 200 mboed Recovered 345mmboe reserves (300mmboe sanctioned) Harsh scaling environment 120 well squeezes p.a. Facilities design for sour service (Corrosion Resistant Alloys) High operating costs circa 50m p.a

4 It will enable million barrels of Enhanced Oil Recovery (EOR) from the Miller Field. DF Strategy Demonstrating the technology (proof of concept) will help the UK in trying to encourage other countries to play a more active part in tackling climate change. The hydrogen power project will deliver as much power as all the UK s current wind farms. It is designed to generate 475MW of base-load, low carbon power. It will permanently store 1.8 million Te per annum of CO2 in the first UK re-use of an oil field for Carbon Capture & Storage (CCS).

6 DF1 Project Overview

7 DF1 Design Shell St Fergus Terminal SAGE St Fergus Terminal Total St Fergus Terminal MRF CO2 Compression Miller Gas System (MGS) Brae Bravo Fuel Gas Braemar Field National Transmission System Dry CO2 (30 bar) Peterhead Dry CO2 (170 bar) Miller Field EOR using CO2 Produced gas reinjection Natural Gas HYDROGEN POWER CCGT with H2-fired turbines ATR Amine Plant CO2 Dehydration Compression Brae Alpha Utilities SSE Power Station Forties Charlie Carbon-free power to market Crude Oil Forties Pipeline System

8 DF1: Objectives 1. Proof of concept and demonstrate industrial scale CO2 system with green power generation. 2. Provide a highly reliable and assured system to store all of the CO2 produced by DF1 in Miller reservoir. 3. Utilise CO2 flood to maximise the economic recovery of further hydrocarbons from the Miller Field. 4. Contribute to organisational capability in upstream CO2 engineering and operations.

9 DF1 Onshore Development Connection into existing infrastructure at Peterhead and St. Fergus Greenfield site preparation at Peterhead Replacement of existing facilities at St. Fergus Peterhead facilities include: Natural Gas Import Desulphuriser Syngas Unit Gas Turbines Heat Recovery Steam Generator Amine CO2 Capture Unit CO2 Dehydration and Low Pressure Compression St. Fergus facilities include: Pipeline pigging facilities High pressure compression

10 DF1 Offshore Development CO2 injection facilities and EOR mode of production till ~2030 Long-term subsea storage of CO2 Existing 30 pipeline import for dry CO2 Oil export via Forties Pipeline System Produced gas re-injected

11 Produced Gas CO2 content Carbon Dioxide Concentration in Produced Gas ~75% - Gas no longer combustible 0.7 Mol Fraction Carbon Dioxide % - Flared gas no longer guaranteed combustible 35% - Miller gas no longer suitable for use as fuel gas Profile Year
