1. Experience with Smart Well on Snorre TLPby
Line Torset Skarsholt , Norsk Hydro
Heine Skeie, Norsk Hydro
Jarle Haga, Baker Oil Tools
FORCE seminar: Value of Smart Wells, March 28-29, 2001

2. Contents Well 34/7-P-30 location Well Objectives Smart well solution
System operations and value

3. Tampen Area

4. Snorre TLP

5. The Snorre Reservoir

6. 400 Segment, Snorre Reservoir

7. Geological Cross section, 34/7-P-30

8. Well Objectives
Primary objective is oil production from Upper Statfjord
Secondary objective is oil production from Lower Statfjord
Obtain early information about degree of fault sealing between 400North and 400 South
Determine if one or two injectors are required

9. Selection criteria Functionality that would fulfil well objectives
Selective clean up of each interval
Easy to integrate with standard completion components
Intervention less installation of completion string
Easy integration of permanent monitoring sensors
Field proven technology

10. System Components “HCM” Sliding Sleeve
Based on the proven “CM” Sliding Sleeve and T5 Safety Valve
Dynamic non-elastomeric seal system in hydraulic section
Control Line Jam Nut System
Control line deployment and protection

11. Final completion schematic, P-30

12. System Value Adding Completion and clean-up phase
Early characterisation of reservoir
”Huff and Puff” production of the well
Optimise the planning of the support injector

13. Well P-30 Production Performance

14. Summary Benefits realised:
Reduced operating cost through zero interventions
Accelerated field production
Optimised production
Improved accuracy of reserves calculations
Identification of reservoir boundaries
Optimum placement of future injection well
Improved risk and safety due to zero interventions
