DynamicLink Downhole Screen
Sand Control
Openhole System
Overview
The DynamicLink Screen open hole system is a profile wire screen completion system, designed to achieve laminar flow conditions primarily in long horizontal wells. The profile wire design helps maximize sand free production that resists damage and erosion for effective, long term sand control.
The DynamicLink no base pipe screen is robust yet lightweight. It is suitable for high mechanical loads, short radius wellbores, and wells with high rate gas flow conditions. It can also be used with or instead of current completion systems.
Whereas conventional sand screens are affected by high inflow velocity of gas or liquid, DynamicLink screens feature specially engineered profiles that force inflow to be distributed more uniformly over a longer length of screens compared with that of conventional screens. This reduces velocity and eliminates erosion hot spots through laminar flow regimes without the need to choke production.
Applications
Onshore and Offshore wells.
Stand-alone completions.
High Rate Gas environment.
Thermal applications, including heavy-oil and steam assisted wells.
Features
No Base Pipe - Minimal Flow restriction.
Robust design.
Suitability for Short- Radius well profiles.
Ability to clear / stimulate through entire joint.
Benefits
Higher reservoir drainage.
Longer Laminar flow preventing erosion.
Longer well life and optimized production.

DynamicLink Screen Liner
Design
This screen, with no base pipe, is designed through forming V-SLOT openings with the venturi nozzle profile.
This is done by configuring two adjacent profiled wires. The no base pipe screens are manufactured using a standardized process that assembles and welds all wire layers in a single systematic operation.
The structural design of the screen uses the basic mass research technique to calculate its permeability, which depends on the screen chosen structure. This technique considers the permeability and flow characteristics for unconsolidated formations in laminar, transition, and turbulent flows.
