Technological advancements have always been the main factor for improving efficiency and minimize costs in the oil and gas industry, the dissolvable frac plug is one of the most exciting innovations in present years. This top-notch technology is transforming hydraulic fracturing operations by eliminating the requirements for post-fracturing intervention.

What are Dissolvable Frac Plugs?

It’s a temporary barrier used in multi-stage hydraulic fracturing operations to isolate specific zones in the wellbore during the fracturing procedure. Unlike conventional plugs that require to be drilled out after fracturing, these plugs are made from special materials that reduce naturally once the fracturing is finished, leaving no residuals behind.

This self-dissolving benefit eliminates the requirement for time-consuming milling operations, making well completions faster, less costly and more efficient. They are prepared for specific well conditions like temperature and pressure, permitting them to disappear without any intervention.

How do these Plugs Work?

The Science behind these wizards' dissolvable frac plugs lies in modern materials that are made from metals or polymers that react to downhole conditions. Let’s see how they work:

●     Isolation of Zones: These frac plugs are set in the wellbore to temporarily isolate various stages during the fracturing procedure.

●     Fracturing Procedure: Once the plug is set, hydraulic fracturing is executed on the isolated zone, preparing fractures in the surrounding rock to release gas or oil.

●     Self-Dissolving: After completion of fracturing, the plug begins to dissolve as it reacts to the specific conditions of the well (pressure, temperature or fluids). With time, the plug fully shattered, leaving no debris behind. 

●     No Milling Need: Far from traditional composite plugs, there is no need to run a mill into the well to separate the plug. The dissolvable plug vanishes on its own, making the procedure seamless.

This innovative design decreases the time and resources required for well completions, providing a more graceful approach to hydraulic fracturing.

Why Dissolvable Frac Plugs Are the Future of Well Completions?

These Frac plugs are gaining quick popularity due to their ability to enhance efficiency and reduce downtime. Let’s deep dive into why this technology is set to shape the future of well completions:

1.   Removal of Post-Frac Intervention:

One of the biggest disadvantages of conventional composite frac plugs is the requirement for post-fracturing intervention.  However, a coiled tubing unit must be run into the well to mill out the plug that can be time-consuming, risky and expensive after the fracturing process. These plugs eliminate this step entirely when the plug disintegrates on its own. This results:

●     No Milling Required: Separating the milling procedure saves both money and time.

●     Lessen Operational Costs: The need for coiled tubing and other post-frac equipment is decreased, which leads to lower operational costs.

●     Less Risk: By reducing the risk of complications or equipment damage, Few tools need to be run into the well.

2.   Faster Well Completions:

You have to agree? Time is money in the oil and gas industry and every minute saved during well competition contributes into essential cost savings. Whereas, these frac plugs provide a faster way to complete wells due to their self-dissolving nature. The benefits include:

●     Rapid Turnaround: Wells can be brought online much faster, since there’s no need for milling.

●     Grow Production: Rapid well completions states production can begin sooner, upgrading overall efficiency.

3.   Decrease Environmental Impact:

These plugs provide eco-friendly alternatives to traditional plugs in oil and gas operations. As these plugs leaves no residue behind, they contribute to:

●     No To Debris: These traditional plugs frequently leave debris in the wellbore after milling which must be removed. On the other hand, Dissolvable plugs dissolve completely and leave no trace at the end.

●     Reduced Waste: The self-mixing nature of these plugs means there’s no need for additional tools or equipment to handle leftover debris that leads to diminish waste.

●     Lower Energy Consumption: Less energy is needed for the overall well completion process that decreases the environmental footprint of fracturing.

4.   Adaptable to Different Well Conditions:

These frac plugs can be tailored to specific well conditions, making them suitable for different applications. It depends on the well’s temperature, fluid compositions, pressure, the materials used to make the plug can be customized to dissolve at the suitable time.

●     Sensitivity to Temperature: The materials can be adjusted to ensure that the plug holds up during fracturing but dissolves when required in the lower-temperature wells. Conversely, for higher temperature wells, plugs are designed to dissolve more rapidly.

●     Pressure-Responsive: Plugs can be engineered to resist the pressure of fracturing but mixing once that pressure minimises post-fracture. 

Conclusion:

These are revolutionising the way hydraulic fracture is done. Their self-dissipation design eliminates the need for time-consuming milling operations, decreases the costs, speeds up well completions and minimises the environmental impact of fracturing.

Well, Vertechs  are coming up for those companies who are looking to stay ahead of the curve, adopting dissolvable frac plug technology.
