Flow Rate Control In Multilayer Injection Using Bridge Eccentric Injection Mandrel

Abstrak

Multilayer injection will increase oil recovery greater than single-layer injection in Water Flood Project. To inject water into many layer are able performed with a single layer completion but it requires a lot of injection well. In the other side, multilayer injection without flow separation has been proven ineffective because of permeability and reservoir pressure. Now, completion system to separate layer can be applied by using multi stage packer, it must be supported flow rate control system as base concept of injection program.
Bridge Eccentric Injection Mandrel has a configuration that provides controller of flow rate at each injection layers. There is Side Pocket Mandrel for placing nozzle that very useful to install Hydraulic Packer and to adjust flowrate accordance with injection target. This technology provides a method to prove the packer has been set and sealed by using Double Memory Pressure Gauge placed in Side Pocket Mandrel. Inside body of Bridge Eccentric Injection Mandrel has a special groove for guide Running & Pulling Tool when perform nozzle adjustment job.
Bridge Eccentric Injection Mandrel gives high accuracy reservoir data for each layer due to proven each packer has been set and seal flow connection between the layers. This technology have a system of separation and flow rate control. It have simple installation system for well completion. Replacement nozzle to regulate flow rate can be conducted using a slick line unit and rig less thereby reducing operational cost.
Implementation this flow rate control technology is able for multilayer injection in every oil field. Monitoring and surveillance for data update can be obtained any time with low operational cost.
