SUBSURFACE CONTROL EXAMPLE: Cone Control
OPERATIONS CONTROL EXAMPLE:Gas lift optimisation
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
FACILITIIES CONTROL EXAMPLES
• Collection of vent gas from oil storage tanks using eductors
• Collection of overhead vapour from glycol regeneration units
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
QUESTIONS
How do you do emissionsforecasting?
Biggest gains really from new
Technology?
How embedded is the use of EIU in project
screening?
How do you track performance?
How do you share ideasacross your organisation?
Responsibility with Operations, Design,
HSE?
Where do you see thebiggest benefits are?
?
Are the biggest steps the ones that create the most
ownership…..?
