The mining industry relies on innovative materials and technology to improve key processes, such as sealing wellbores. The wellbores can contain multiple sections to be mined sequentially. After a section has been completed, it must be sealed off to prevent pressure loss while fluids are pumped from other areas.
Finding the safest and most cost-effective way to secure a well is crucial. Tempered glass plugs are an innovative and extremely effective solution to these challenges, offering durability, safety, and reliable protection.
The Strategic Advantage of the “Pause”: Why Miners Use Temporary Well Abandonment
Temporary well abandonment is a strategic tactic used to put a well into a holding pattern between drilling operations and completion. It differs from drilled-but-uncompleted (DUC) wells in that it is a planned phase in mining operations that can safeguard the wellbore’s integrity while it remains in a holding pattern. This practice is beneficial for several key reasons:
- Supports batch completion. In large-scale mining projects, operators drill multiple wells sequentially. By temporarily abandoning each one as they drill new areas, it’s possible to seamlessly complete the drilling phase and then have completion crews handle all wells simultaneously for improved efficiency.
- Prevents logistical and equipment delays. Mining operations require an extensive amount of machinery that can be delayed or may require repairs. Temporary abandonment is a cost-effective way to pause operations when problems with equipment or processing facilities occur.
- Helps mining companies navigate fluctuating market conditions. When fluctuating commodity prices become unfavorable, immediate extraction can become unprofitable. In these situations, pausing a well allows mining companies to safely wait for improved market conditions without losing their investments.
The Swift Glass Solution: Controlled Shatter With Tempered Glass Plugs
Traditionally, metal or composite material plugs have been used to block off wellbores. However, creating these plugs is expensive and time-consuming. They require extensive drill-out and retrieval operations. Removing a traditional plug is labor-intensive and hazardous to workers. A more effective alternative is to use shatterable tempered glass plugs.
This innovative solution is made from durable tempered glass that withstands a wellbore’s high-pressure conditions yet breaks down as needed under designated conditions. The thermal glass tempering process for these glass plugs creates immense compressive stress on the core’s surface and tension. This makes the glass as much as four times stronger than standard glass.
Tempered glass plugs are resistant to impacts, thermal shock, and the corrosive downhole environments that oil, gas, and petrochemical mining sectors experience. However, the plug’s most important quality is their ability to “shatter” when no longer needed. Instead of simply breaking, the tempered glass safely disintegrates into a fine powder.
Crucially, this controlled disintegration eliminates the need for plug retrieval. With tempered glass plugs, the glass fragments are small enough to be circulated out of the wellbore along with the fluid, resulting in reduced labor costs, significant time savings and reduced downtime, and improved safety.
Key Mining Applications for Temporary Well Plugs
Temporary well plugs are suitable for many mining environments, including:
- Dewatering wells. These wells are designed to lower groundwater levels so that mining operations can occur. They are often paused during specific project phases.
- Exploratory drilling. Drilling test holes is an important first step in mining projects. Exploratory drilling assesses the mineral potential of an area and must often pause temporarily while data is analyzed.
- Geotechnical investigation. Mine planning often requires multiple wellbores to explore an area’s soil and rock mechanics. These wellbores must be safely paused as other areas are explored.
- Zonal isolation. Complex wells involve multiple geological zones and staged extraction phases. Temporary well plugs safely isolate certain areas as needed.
