MultiFrac™ System

Overview

Tartan Completion’s MultiFrac™ limited-entry, ball-drop system combines patented MultiFrac hydro-mechanical sleeves with patent-pending BurstPoint™ ports to improve stimulation treatment placement and effectiveness. The MultiFrac system simultaneously stimulates multiple stages (cluster) with a single fracture treatment at surface.

By enabling increased stage count without increasing the quantity of activation balls, this system is designed to provide a higher density of stages to evenly distribute stimulation treatments throughout the entire wellbore. The MultiFrac system provides complete control of the stimulation while offering a more complex fracture network.

Application

• Single design for open hole or cemented liner installations
• Cluster (batch) stimulation of multiple stages at the same time
• Ability to stimulate 150+ stages

Features and benefits

• Faster completion times due to limited-entry stimulation of multiple stages with a single treatment from surface
• One ball activates multiple MultiFrac sleeves, allowing for higher stage density within the same length of wellbore
• MultiFrac sleeves have no communication with the annulus until BurstPoint port rupture pressure is reached
• BurstPoint port inserts prevent erosion, allowing cluster efficiency of ≥90% throughout the treatment stage
• BurstPoint ports can be sized to control the fracture fluid rate on a per sleeve basis
  • Adjustable stimulation volumes enabling true limited-entry operations
  • Positive surface indicators of multiple entry points, providing real-time parameters
  • Enhanced fracture network results in increased wellbore conductivity
• Surface pressure indications are an accurate monitor of tool performance
• Rugged design for enhanced reliability
  • Can be rotated to bottom
  • Designed to handle the high torque capabilities of all premium and semi-premium connections
• Ball seats are designed for quick mill-out times
