2. Facilities control Operations control Sub-surface control Introduction

3. Monitoring and SurveillanceWithout monitoring no optimisation ‘FieldWare Production Universe’

4. SUBSURFACE CONTROL EXAMPLE: Cone Control Simple surface instrumentation & control

5. SUBSURFACE CONTROL EXAMPLE: Cone Control

6. OPERATIONS CONTROL EXAMPLE:Gas lift optimisation

7. OPERATIONS CONTROL EXAMPLE:Gas lift optimisation • Customer experience • 5 - 15% more production using significantly less gas lift gas • Production sustained during gas lift compressor outage • Easier for operator to stabilize process after compressor outage • HSE impact • Less compressed gas needed for oil lift • Sending Operators less frequently to hazardous locations

8. FACILITIIES CONTROL EXAMPLES • Collection of vent gas from oil storage tanks using eductors • Collection of overhead vapour from glycol regeneration units

9. INCREASED AWARENESS: Emissions Forecasting • Use of EIU • Allows to quantify and compare the impact on the emissions for several options. Helps in decision making • Use of IPSM for Production Forecasting (instead of decline curves) : • Enables early identification of Environmental effects (Production System Optimisation) and quantification of associated: • Emission volumes • Energy consumption

10. QUESTIONS How do you do emissions forecasting? ? How embedded is the use of EIU in project screening? Are the biggest steps the ones that create the most ownership…..? How do you track performance? Where do you see the biggest benefits are? How do you share ideas across your organisation? Biggest gains really from new Technology? Responsibility with Operations, Design, HSE?
