Variperm’s Q-Controller^™ is a liner-deployed autonomous, nozzle-based inflow control system for vertical, horizontal or deviated well completions. The Q-Controller independently and autonomously controls water breakthrough. Oil production is unhindered with the Q-Controller design and is preferentially produced over both water and gas. Installing multiple Q-Controllers can improve recovery rates and optimize the inflow profile along the production interval. Each Q-Controller is completed and custom designed with Variperm’s direct wrapped screen, resulting in large open flow areas for optimal exposure to the reservoir sand and producing interval. The Q-Controller is applicable for optimal inflow distribution control and increases productivity. An integrated wire-wrapped screen for reservoir-specific sand control is combined and deployed in a single trip.

Features and Benefits

• Engineered nozzle sizes along the work string for uniform inflow profile
• Sand Control options include proSTRAIGHT^™, proSEAM^™, proWRAP^™, proPUNCH^™, proMESH^™, and proPACK^™
• Flush OD to match blank casing and large ID bore access
• Zonal isolation in each independent area of formation it resides in for optimal control
• High Torque-Sealed Connections allow rotation of the Q-Controller^™ liner during installation
• Improved recovery rates, production optimization and well management
• Tungsten carbide nozzles reduce erosion and corrosion
• Pressure drop across nozzles are viscosity insensitive; High-flowing velocity water can be choked effectively by higher pressure drop
• Nozzles can be plugged into Q-Controller at rig-site with minimal handling
• Variperm’s proprietary wellbore simulation software (NALU) creates custom nozzle size design
