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

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

Tampen Area

Snorre TLP

The Snorre Reservoir

400 Segment, Snorre Reservoir

Geological Cross section, 34/7-P-30

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

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

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

Final completion schematic, P-30

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

Well P-30 Production Performance

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
