ResInject* Injection Control Device
The ResInject* injection control device from Schlumberger provides an elegant solution to a vexing problem using an innovative application of fluid dynamics principles. By removing the flow-control interface from 
the screen surface to a controlled environment, the flow regime is changed from the traditional Darcy spherical flow shape factor to Bernoulli flow, which is viscosity independent. Using configurable ceramic nozzles to control injection fluid flow rate, the pressure drop across the system can be designed for the zone to be treated. As a result, low permeability zones receive more injection fluid than those treated using a normal screen configuration, thereby increasing ultimate oil recovery.
The ResInject device is designed using a proprietary process based on sound reservoir engineering principles and using both static and dynamic simulators to model performance. Predicted results have been corroborated by subsequent production logs, proving that actual performance can be tied back to system design. Volumes are designed so all pressure drop occurs in the metering section so results can be predicted and replicated.
