MeshPort

MeshPort™  Dynamic Downhole Flow Control-Sand Control System

MeshPort flow control completions allow operators to remove formation damage from drilling and completion fluids, delay water influx, optimize toe-to-heel inflow, and improve sweep efficiency across horizontal wells. It integrates PremiumPort™, dynamically configurable nozzle based inflow and injection control devices that can be reconfigured over the life of the well, with MeshRite™ high performance sand control.

MeshPort’s multi-position valve can be shifted to close or open nozzles/ports strategically positioned at the end of each sand control joint

 

Flexibility in activating the nozzles over the life of a well allows operators to control and change the pressure profile along a lateral repeatedly as the reservoir conditions change. MeshPort’s sand control sections are comprised of MeshRite, which is formed by wrapping stainless steel mesh wool over perforated base pipe and covering the joint with a perforated shroud. MeshRite’s unique 3 dimensional pores create exceptional open flow area and high plugging resistance that has proven ideal for controlling heterogeneous sands with wide particle size distributions.

The Challenge

Well completion decisions must balance the need for efficient sand control with optimal well productivity and cost concerns. Operators are recognizing that all the intervals along laterals do not contribute production equally. They need effective ways to better manage the pressure profile along the wellbore in order to clean up drilling fluids and delay water influx as the well ages. Another operational concern is sand interfering with flow control nozzles, or entering the wellbore over time which can reduce well productivity, damage surface facilities, or worse, cause expensive remediation and catastrophic well failure.

The Solution

MeshPort combines the most flexible flow control technology in the market with the top performing screen for oil and gas reservoirs.

  • Nozzle based flow control is viscosity independent which leads to delayed water influx. The flow control capability integrated into MeshPort can also be tailored to reservoir potential at each interval based on the style and orifice size in the nozzles.
  • The flow control capability can be modified over the life of the well by activating a multi-position valve downhole to close or expose nozzles.
  • Unlike gap based screens, MeshPort screen sections do not require detailed and expensive particle size analysis and have 40% open flow area.

Why Is Understanding Sand Retention And Flow Behavior At The Sand-Screen Interface Important?

MeshPort Performance

Dynamic Flow Control for Advanced Well Productivity

MeshPort’s nozzles provide pressure profile control along the wellbore, and the screen sections stop harmful sand from entering the wellbore. Fluid flows through the MeshRite filter media, along grooves in the base pipe to the nozzles which are viscosity independent flow control devices. Grooves in the base pipe create a large flow area between the screen media and the base pipe prevent erosion and any undesirable pressure losses.

MeshPort can be configured for injection control.

MeshRite Outperforms in Retained Permeability

MeshPort sand control sections are insensitive to variations in formation particle sizes which lowers risks when the particle size distribution is not known, or varies a lot from heel to toe. It also saves the costs of detailed sand sample collection and laboratory analysis. Operators gain a high performance sand control system with the ability to reconfigure the well completion throughout the life of the well for inflow and injection control.

Viscosity Independent Flow Control

Unlike channel or tube-based ICDs, nozzles are viscosity independent which allows them to delay water influx. The chart in Figure 3 shows pressure drop measured for various fluids through a 4.00 mm nozzle.

MeshPort Applications

MeshPort is best suited for unconsolidated, non-uniform sands for the following wells:

  • Horizontal producer or injector wells requiring pressure profile control and sand control along the entire wellbore
  • Vertical wells with commingled zones of different pressures
  • Thermal wells that require uniform toe-to-heel steam injection
  • In combination with external swell packers to isolate zones and minimize annular flow

Benefits

MeshPort’s multi-position valve can be shifted to expose ports which can be plugged, left as open ports, or fitted with nozzle based flow control. The nozzles are configured for inflow or injection control at the wellsite prior to deployment. The valve can be repositioned downhole to select ports in any order as many times as required using coil tubing to run the Harrier shifting tool to:

  • Change the pressure profile along the lateral, shut off intervals, or stimulate the well
  • Facilitate uniform toe-to-heel sweep of reservoir
  • Delay onset of water/gas/steam coning for increased reserve recovery and net present value
  • Choke off water zones and isolates shale zones
  • Create a viscosity independent pressure drop which is a distinct advantage over channel based flow control
  • Allows operators to tailor flow control strength to the reservoir profile.

MeshPort Options Available

MeshPort can be configured with three different nozzle styles, each of which can be supplied with a selection of orifice sizes.
