Vigor Mirage™ 7” Dissolvable Frac Plug
Description
Vigor Mirage™ 7” Dissolvable Frac Plug is a fully dissolvable frac plug that provides a dependable method for temporary zonal isolation during fracturing operations in both vertical and horizontal completions.
The compact design eliminates milling and post-frac cleanout, leaving no debris to remove from the well. The minimalist design has 60 to 70% fewer parts than competitive products, leaving less material in the well to be dissolved.
Features
Faster production – These plugs eliminate the need of drilling out the plugs as they dissolve, allowing operators to produce much sooner.
Reduced expenditure – Unlike traditional frac plugs, the dissolvable frac plugs require a lower-cost clean-up run to remove residual proppant from the wellbore which saves thousands of litres of diesel that is used during the coiled tubing (CT) milling, saves time and manpower as well.
Longer laterals – No major milling equals no length restrictions related to coiled tubing reach which means longer laterals and more scope of production.
Significant reduction in greenhouse gas emissions – The life-cycle carbon footprint of the dissolvable plug is estimated to be 91% lesser per wellbore than the conventional plug.

How to Choose the Right Dissolvable Plugs
Selecting the appropriate dissolvable plugs—either dissolvable frac plugs or dissolvable bridge plugs—is critical to the success of hydraulic fracturing operations. The choice depends on various factors related to well conditions, operational requirements, and desired outcomes. Here are some key considerations to guide your decision:
1. Operational Objectives:
If the primary goal is to achieve temporary isolation for fracturing fluid injection in horizontal or complex well sections, dissolvable frac plugs are the better choice. Their straightforward design allows for precise control and quick deployment.
Conversely, if the objective is to provide long-term sealing for oil and gas formations, especially in horizontal and multilateral wells, dissolvable bridge plugs are more suitable. They are designed to maintain pressure integrity during extended isolation periods.
2. Well Characteristics:
Evaluate the complexity of the wellbore. For wells that require accurate control over fracturing fluid placement, dissolvable frac plugs are advantageous.
In scenarios where the well features multilateral branches or needs extended pressure maintenance, dissolvable bridge plugs provide the stability and sealing performance required.
3. Dissolution Requirements:
Consider the timing and conditions under which the plugs need to dissolve. If the operational strategy requires dissolution at a specific time and location, focus on dissolvable frac plugs, which are designed for quick and effective performance.
For operations where long-term sealing and subsequent dissolution are essential, opt for dissolvable bridge plugs. Their design prioritizes reliability during the fracturing process and ensures complete dissolution post-operations.
4. Technical Challenges:
Assess the technical challenges specific to each plug type. If ensuring dissolution at the right time and location is critical, dissolvable frac plugs may present fewer complications.
If the emphasis is on providing reliable sealing throughout the fracturing operations while ensuring complete dissolution afterward, dissolvable bridge plugs will be the better option, despite the added complexity in their application.
