Intelligent completions obtain downhole pressure and temperature data in real time to identify problems in the reservoir or wellbore and optimize production without costly well intervention. Sensing, data transmission, and remote control of zonal flow to isolate the formation from completion fluids help operators minimize fluid loss, manage the reservoir, maintain well integrity, and maximize production.
Flow Control
Flow control valves are used in multizone intelligent completion, comingled-flow completions, auto (natural) gas-lift wells, and well environments with scale deposition, severe erosion, or high temperature conditions.Flow control valves modify the flow behavior as required for specific operations and can be operated automatically, manually, or remotely as part of an intelligent completion. Used to control upper and lower producing zones, they reduce the production of unwanted water and gas, minimize the costs and risks of well interventions, and maximize well productivity.
Permanent Monitoring Systems
WellWatcher permanent monitoring systems
WellWatcher permanent monitoring systems integrate the most advanced permanent downhole gauges with surface data communication to allow remote monitoring of wells and reservoirs in real time. Pressure, temperature, and flow rate data are transmitted to remote location via satellite, Internet, or cable.
WellWatcher Flux System
The system obtains reservoir data across the sandface of subsea wells in real time to monitor and characterize flow profiles. Electromagnetic induction enables wireless communication and power transmissions between the upper and lower completions.
WellWatcher DTS Fiber Optics
The system captures and transmits distributed temperature profiles with fiber optics reliably, accurately, and in real time to identify the time, location, and reason for changes in flow. Data are transmitted to the surface and then to remote locations via satellite, Internet or cable.
Pressure and Temperature Gauges
These gauges obtain highly accurate, stable measurements with gauges ranging from simple systems to downhole networks.
WellNet Downhole Network and Communication Systems
This telemetry system provides bidirectional, high-rate data communication and transfers electrical power to downhole tools.
Conveyance Components
Connectors and cables are rigorously tested and qualified to meet the highest standards for reliability.
Zonal Isolation
QUANTUM Multiport Packer
The QUANTUM multiPort (QMP) packer is a hydraulically set retrievable packer particularly suited for bypass applications. It is used as the upper packer in stacked configurations in completions with surface-controlled subsurface flow-control valves and tubingmounted reservoir monitoring equipment.
This packer is designed to allow onsite feed-through and connection of electric and hydraulic conduits. Testing of control-line fittings on the packer is accomplished after feed-through. This feature greatly simplifies rig operations and reduces control line terminations. The packer features a one-piece mandrel design with an eccentric flow bore. Bypass lines are fixed relative to the mandrel, eliminating relative movement during releasing. This design facilitates release regardless of the prevailing tubing load condition, i.e., tension or compression at the packer. The QMP packer allows simultaneous setting of multiple packers and is capable of simultaneous testing of bypass seals on the rig floor.
The hydraulically set QMP packer features twin setting pistons that fully energize the sealing elements prior to anchoring the slips.
Retrieval of the QMP packer is accomplished by means of a through-tubing intervention tool and subsequent upward pull on the tubing.
QMP packers are available for a variety of service applications, including H2S and CO2 environments.
The QMP packer is designed and tested in accordance with ISO 14310 grade V3.
Benefits
- Simplified operations reduce rig costs.
- Enhanced capabilities allow onsite product customization.
- Reduced rig time achieved by simultaneous setting of multiple packers.
Project Management
Intelligent completions present a wide range of complex technical challenges, especially in deepwater. The Schlumberger Project Management group works closely with operators to plan and design projects; manufacture, test, and install equipment; ensure equipment reliability; and troubleshoot complications. Close collaboration with the operator is considered critical to the success of each project.
