Integrate multistage stimulation and mechanical sand control
The Ratek Proppex™ frac sleeve combines precise stage-by-stage stimulation with post-frac sand control in one completion-integrated system. After stimulation, the sleeve positions a mechanical screen across the frac ports to help prevent proppant and formation sand from entering the wellbore during flowback and production. Built on the field-proven Innovus™ platform, the multicycle sleeve reduces sand accumulation, cleanout requirements, and artificial-lift equipment wear while maintaining operational flexibility throughout the well lifecycle.
Frac
Accelerated operational speed while maximizing fracture height and growth
Isolate
Isolate unwanted zones, reestablish wellbore integrity, and execute out-of sequence fracturing with reclosable sleeve funtionality.
Produce
Open unfiltered production mode allows you to produce without mechanical sand control as required.
Screen
The wire-wrapped screen is designed to resist plugging and erosion with best in class sand control.
Base Pipe
The perforated base pipe is the central tubular structure which supports the rib- and wrapped-wire assembly. It is the primary conduit for production fluids to flow from the reservoir to the wellbore. The base pipe is designed to handle high-pressure and high-velocity conditions. Its durability ensures long-term reliability in demanding downhole environments.
Rib Wire
The rib wire, in a wire-wrapped screen, provides structural support to the screen assembly. These wires run along the length of the screen, acting as a backbone to maintain the integrity and shape of the screen under high reservoir pressures.
Wrap Wire
The wrap wire is wound around the rib wires in a spiral. It forms the filtration surface of the screen. The wrap wire is designed with precise gaps small enough to block formation sand and proppant while allowing hydrocarbons to flow freely into the wellbore.

Ratek Proppex Re-Open Tool
Ready. Set. Screen.
The Ratek Proppex re-open tool is a bottomhole assembly (BHA) deployed on coil or jointed tubing to shift the Ratek Proppex sleeve into position across the frac ports for screened production.
Seamless Actuation
Bi-Directional Slips
The shift-frac-close method eliminates the need to reposition tools to open or close sleeves, all with a simple, mechanical design.
Precise Locating
Sleeve Locator
A mechanical, debris-tolerant design eliminates operational limitations of pump activated locators.
Position with accuracy at any depth without relying on a lock-in-place or a pressure-activated tool.
Consistently locate and confirm when the sleeve is open for seamless stimulation and long-term multicycle operations.
Compatible Integration
Bullnose Crossover
The Ratek™ frac isolation assembly (FIA) is designed for unconventional reservoirs. The crossover design can be connected to accommodate additional auxiliary tools such as memory gauge tools.
Mechanical Sand Control
The Ratek Proppex frac sleeve is the all-in-one tool combining cementable sand control with shift-frac-close functionality. The sleeve operates in four distinct modes for operational flexibility. It excels in low-mobility environments with unmatched reliability in sand-laden fluids.
