The Generic Choke Model enterprise ( GCMe )

1. The Generic Choke Model enterprise (GCMe) What will be the value of your organisation’s annual production losses? Where will your efforts/OPEX best be targeted in increasing production efficiency? GCMe will help you answer these questions and support your people in the drive to continually Improve Performance… “By doing this we cut our losses in half, year on year, for three years in a row on the Magnus Platform” (Andrew Goodwin, BP)

2. GCMe What is GCMe? • Establish the true Production/Injection Potential GCMe helps you too: A powerful, user-friendly toolset which supports a “joined-up” approach to Production & Injection Optimisation. • Analyse and learn from your loss events and prevent future losses occurring • Invest wisely to improve your capacity

3. GCMe Principles • Supports A Multi-Discipline People Process • Provides a focal point for all production (and Injection) performance issues • Harnesses the Expertise, Experience & Insight of the Offshore & Onshore teams rather than just capturing automatically generated values • Complements existing specialist systems – easy to integrate where appropriate • Covers the entire supply chain from reservoir to market • Designed to engage users, embed ownership and most importantly, Drive Performance Improvement.

4. Installed Capacity - Your Daily Production Target This view facilitates the regular multi-discipline team meeting which analyses the bottlenecks across your complete supply chain. As the component parts are “in series”, the lowest capacity (Wells) restricts the overall capacity for Alpha Platform Capacities of component parts are automatically rolled up to Alpha Platform Production Capacity decision level

5. Losses to be allocated Performance Data Capture Made Easy Daily production figures pulled through from external database Any loss event previously flagged as a “continuing loss” is automatically inserted. Capacity automatically pulled through from internal decisions Losses are allocated to a System Source from the hierarchy. Together with an Equipment Source form a generic list and a Cause.

6. Facilitate Your Performance Review • The performance reviews are powered by GCMe’s reporting suite • The central database holds all the data for all the Assets. Every Source & Cause is mapped to a Generic Source & Cause allowing comparison across assets. • Drill Down/Roll-Up to any level in your organisation. Almost all of the reports can be edited, filtered and customised using the parameters form GCMe includes an extensive suite of reports, most of which are available at all levels of the organisation

7. Analyse Your Performance • As each source and cause has a local “owner”, you will be able to see who else has encountered the same problems and start a conversation. • The reports are easily exported to other windows applications and there is the facility to export the underlying data for further analysis in Microsoft Excel. Trends help you predict if and when a loss event may happen in the future The sources of loss over any given time period – in descending order of impact. View by any unit of measure – even $ value. Same report available for Causes & Owners. Production Performance Report. Known as “Blood On The Wall”. Instant Visibility of Losses.

8. GCMe Be Proactive – Prevent Future Losses An estimate of timing and impact is recorded as part of a Potential Loss which drives the GCMe Potential Loss risk matrix. The purpose of this process is to try to prevent future unplanned losses occurring! Taking a more proactive HSE style approach rather than just reacting to events after they have happened… This is achieved by capturing: Observations Near Misses If not resolved, through time, Potential Loss events move from left to right – eventually becoming urgent Recurringloss events

9. Colour coding identifies the opportunity status In this example the opportunities associated with individual wells and the “Wells” group, stack up to provide a significant potential increase in Production Capacity (at this level). Unlock Potential/De-Bottleneck • Production Capacity growth opportunities may be identified in all areas of the Reservoir to Market production process. • GCMe logically rolls up these opportunities to the level where informed decisions can be made regarding which, if any to pursue. Growth Opportunities are logically rolled up to any level in the hierarchy, along with capacities. At this level, it is clear that there is value in pursuing the Wells, Nominations & Local Plant related opportunities – but little value in pursuing the others at this time. The Building Blocks of Production diagram details the rolled up opportunities for Alpha including the Theoretical Production Capacity (TPC) and the Production Technical Limit (PTL)
