Dynamic flow control allows operators the flexibility to manage the pressure profile along laterals over the life of the well to delay water influx and improve well productivity. Completions using wire wrap screen for sand control are best suited to homogeneous oil and gas reservoirs with larger and uniform particle size distributions.

This flexibility in activating nozzles allows operators to control and repeatedly change the pressure profile along a lateral over the life of the well. Tailoring flow control aids in removing formation damage from drilling and completion fluids, delay water influx, and optimizing toe-to-heel inflow. AccuPort’s sand control sections are comprised of keystone shaped wire continuously wrapped and spot welded over perforated base pipe. The uniform gap size between each wire is sized to the specific reservoir characteristics. Unique applications can be addressed with erosion-corrosion resistant metallurgies and variety of options for length and diameter of the base pipe and screen sections.
Well completion decisions must balance the need for efficient sand control with optimum well productivity and cost concerns. Operators are recognizing that all the intervals along laterals do not contribute production equally and the pressure profile of a well can change over the life of the well. They need effective ways to better manage the pressure profile from toe-to-heel of the well in order to delay water influx as the well ages. Another concern is sand entering the wellbore over time can reduce well productivity, damage surface facilities, or worse, cause expensive remediation and catastrophic well failure.
AccuPort combines the most flexible flow control technology with a conventional gap based screen that is best suited to more homogeneous oil and gas reservoirs with larger and uniform particle size distributions.

AccuPort can be configured for either production or for steam or chemical injection at the wellsite prior to deploying the screen system. For injection, the port plugs are removed, threaded nozzles installed and plugs are reinstalled. Fluids are pumped into the wellbore and exit through nozzles that are strategically placed so thief zones are shut off and injected fluids have their intended impact. The AccuPort flow path directs the fluid into the near wellbore area at the sand-screen interface for uniform injection of gas, water, or steam from toe-to-heel of the well.
Unlike channel or tube-based ICDs, nozzles are relatively viscosity independent as shown below with pressure drop through a 4.00 mm nozzle measured for various fluids. Viscosity independent nozzles enhance oil production while delaying or stopping water influx.
A number of factors influence proper completion design. Absolute’s Technical Application Managers are available to assist you in achieving optimal well performance through:
For heterogeneous sands and fines, MeshPort™ which is made with MeshRite™ screen is more effective. For cost sensitive applications, Tri-D FacsPort can be a more effective alternative to slotted liner and wirewrap screen. For corrosive reservoir environments Tri-DPort may be better. Flow control/sand control completions can be configured and tailored to specific formation characteristics, production requirements, and cost constraints.
