Removing sand or filling a well bore Fracturing/acidizig a formation Unloading a well with Nitrogen Gravel Packing Scale removal (hydralic) Thank you for your time. Any questions?? - “What was once a fringe service has moved to center stage in the oilfield theater of operations.” Coiled Tubing Data Acquisition InterACT service Monitors all well construction and wellsite operations Mobile app available CoilCAT Real-Time Treatment System Provides visual wellbore and CT string data during well intervention Merges design, execution, and real-time evaluation capabilities to analyze problems Allows real-time job redesign that accounts for unexpected conditions Coil Tubing Perforating The rigidity and strength allows enduring greater forces Both compressive and tensile forces Operational advantage when perforating Ideal for live wells Pressure control techniques used to run long gun strings Retrieve the guns without killing the well Several Ways to activate CT guns Hydraulic delay firing heads Dropball firing heads eFire-CT firing system using circulation rates “stiff-wire”CT where done by enabling the guns through an electric line Power Pack Coiled Tubing Injector Head Tubing Reel Control Cabin CT Express 12.5 % total cost savings Reduced rigtime Lower maintenance cost Combines capabilities of 4 trucks into 2 tractor trailer units Well hole Setting a plug or packer Perforating Logging Sliding sleeve operation Running a completion Straddles for zonal isolation Drilling Mechanical Workover Activies Pumping Removing sand or fill from a wellbore Fracturing/acidizing a formation Unloading a well with nitrogen Gravel packing Scale removal (hydraulic) Coiled Tubing: Introduction A conveyance tool for well intervention Designed to improve well and reservoir performance Pumping Mechanical X-11 Improves Safety Fail-safe system Well site delivery process Flexible, fit-for-purpose design Reduces footprint by stacking CT Seas Economic offshore answer Reduced crane lifts CT Tcomp Fit-for-purpose for deepwater operations Increases Operating efficiency Safety Reduces Operating cost Wellhead stress Rigtime Schlumberger’s Product Portfolio Live Downhole Coiled Tubing Services Integrated Coiled Tubing Production Service CoilFRAC Coiled Tubing Perforating Data Acquisition Live Downhole Coiled Tubing Services ACTive family for real-time downhole measurements Opportunity to monitor and evaluate job progress and intervene with one trip in hole ACTive CT services for a variety of applications Matrix Acidizing: Control of injection rates and monitors downhole pressure and temperature to optimize fluid volume and penetration Wellbore cleanout: uses differential pressure readings to avoid damage to formation and reducing the number of trips Perforation: ensuring target coverage while monitoring hydrostatic balance Zonal Isolation: for sealing elements, fluid placement for specific isolated zones in a single run Lift Operations: displaces completion fluid by injection nitrogen DTS profiling: a 3D temperature profile of wellbore to monitor treatment and enhance all mentioned functions Integrating Coiled Tubing and Production Logging for Conoco Phillips Compare production monitoring capabilities of fiber optics to understand fracture and completions program effectiveness in using production logging technologies Use ACTive PS integrated CT to acquire logging data and distributed temperature survey (DTS) measurements in a single run Validated production monitoring capabilities of fiber optics Strong correlation to wireline production logs Reduced cost, time, and risk Saved one trip downhole for each well 2010 Solution Challenge Result Tool & Bottom Assemblies Wellbore Fill Removal Service Coil Tubing Logging Head System Retrieval and Fishing Tools Through-Tubing inflatable Packer Hangers, Plugs Multilateral Reentry System
