FracFilter™ is an integrated fracturing control, sand control, flow control and injection control system installed as a well completion liner prior to stimulation. Fracturing port capability is integrated into the PremiumPort™ multi-position valve system. Changing the valve position allows ports to be closed or opened multiple times to enable stimulation and inflow control as the well ages. The valve is shifted reliably downhole as required using the Harrier™ tool run on coil or jointed tubing.Download Brochure » Contact Us »
PremiumPort is a multi-position valve made of exotic alloys and special seals to handle the harshest conditions. FracFilter allows a well to be fractured with a PremiumPort which is set for the open position for fracturing. The valve can then be shifted to close the fracturing port and divert flow through the screen’s filter media, such as MeshRite, Tri-D FacsRite, or AccuRite, to allow proppant flowback control.
While fracturing a formation can significantly improve reservoir productivity, proppant flow-back creates the same well performance issues as the migration of formation sands. These issues include degradation of near wellbore permeability, screen erosion, and sand blocking well production when it enters the wellbore.
Conventional multi-stage fracturing systems cannot control the pressure and production profile along a lateral for either injection or production modes. They also limit the remedial work that can be performed within the wellbore to ensure each zone is producing to maximum efficiency.
FracFilter is based on the PremiumPort valve system which is built with an integral fracturing port capability.
By shifting the valve position after fracturing is complete, formation sands and proppant are blocked from flowing into the wellbore, and additional ports can be opened, closed, or combined for injection and/or flow control.
Multiple FracFilter assemblies can be economically placed within a horizontal segment to allow initial as well as subsequent fracturing operations, as required.
Why is Retained Permeability Important in Sand Control?
FracFilter is an ideal solution for unconventional reservoirs characterized by:
Multi-stage stimulation technologies and tools currently used in unconventional reservoirs are also being applied to more productive and unconsolidated reservoirs to improve recovery. In such reservoirs, technologies like FracFilter are essential to allow for proper stimulation and production in:
FracFilter allows operations to maximize production and intervention options available to stimulate the reservoir and increase permeability without increasing risks or compromising well life.
A well completed with FracFilter in combination with MeshRite has one of the most successful sand control technologies on the market, proven to maintain high near wellbore permeability, high open flow area, and high erosion and plugging resistance.
FracFilter includes all of the performance advantages of a dynamic inflow and injection control system. Additionally, it can be adjusted over the life of the well to optimize production.
The standard FracFilter configuration is integrated with MeshRite sand control; however, any sand control system or sections of blank pipe can be integrated with FracFilter depending on the application. The mechanical properties may change depending on the design.
