PGA Degradable Bridge Plug

The PGA Degradable Bridge Plug is a revolutionary downhole isolation tool designed to address the pain points of traditional bridge plugs, such as residue accumulation, costly mill-out operations, and environmental pollution. As a key component in multi-stage fracturing, it provides temporary and reliable zonal isolation during fracturing, then completely degrades into carbon dioxide and water under downhole conditions-no harmful residues, no additional intervention, and no damage to the formation permeability.

Our product is widely applied in unconventional oil and gas development (shale gas, tight oil), old well reformation, and horizontal well multi-stage fracturing. It has been successfully promoted and used in nearly 150 wells in major oilfields, proving its stability and efficiency in complex downhole environments.

1.Fully Biodegradable & Eco-Friendly : Made of 100% PGA material, the plug degrades completely into non-toxic CO₂ and H₂O under downhole temperature and pressure conditions, eliminating the need for acidizing or milling operations. It effectively reduces formation damage and meets global environmental protection standards for oil and gas exploitation.

2.Superior Mechanical Performance : The PGA material features excellent mechanical strength, heat resistance, and pressure-bearing capacity, capable of withstanding high downhole temperatures (up to 400°F/204°C) and high fracturing pressures (up to 10,000 psi/68.9 MPa). It ensures stable isolation during the entire fracturing process without deformation or failure.

3.Predictable & Controllable Degradation : Through advanced material modification technology, we can customize the degradation time (2-10 days) according to downhole temperature (40-120°C), mineralization degree, and construction requirements. It solves the problem of slow degradation in medium-low temperature zones and ensures complete degradation without residue blockage.

4.Cost-Saving & Efficient : Eliminates expensive mill-out and cleanup operations, shortens the well completion cycle, and reduces labor and equipment costs. Compared with traditional metal bridge plugs, it can save 30%-50% of related operational costs while improving fracturing efficiency.

5.Easy Operation & Wide Compatibility : Compatible with standard industry setting tools, supporting drop ball, ball-in-place, and pump-down ring options. It can be run at speeds up to 500 ft/min and 18 bbl/min, adapting to various casing sizes and wellbore trajectories, and is easy to install without special equipment.

6.Reliable Isolation & Fracturing Effect : Equipped with high-strength degradable rubber sleeves and spray-type slip structure, the plug forms a tight seal with the casing wall, ensuring no fluid channeling between layers. It assists in forming a spider-web-like fracture network, improving reservoir reconstruction volume by up to 160% compared with conventional fracturing methods.

Our PGA Degradable Bridge Plug has passed strict indoor performance tests and large-scale field applications, with remarkable results :

- Indoor Test: Under 120°C and 70 MPa pressure, the plug maintains stable isolation for more than 8 hours, with no leakage. Degradation is complete within 5 days, leaving no residue.

- Field Application: Successfully applied in Fuling Shale Gas Field, Jianghan Oilfield, Southwest Oilfield, and other major oilfields. In Pulu Ye 1HF Well, the comprehensive sand-liquid ratio was increased to 8.2% after application, and the fracture complexity was higher than that of the same type of reservoir. In Ning 209H36-5 Well, the maximum fracturing pressure reached 105 MPa, and all construction parameters met the design requirements.

- Unconventional Oil and Gas Well Fracturing: Shale gas, tight oil, coalbed methane horizontal well staged fracturing, which can effectively solve the problem of difficult drill cuttings flowback in low-pressure and low-salinity gas wells.
- Old Well Reconstruction: Repeat fracturing reconstruction of old oil and gas wells, avoiding the damage to the original wellbore structure caused by milling and fishing of traditional bridge plugs, and improving the reconstruction efficiency.

- Deep and Medium-Depth Well Construction: It can withstand the high temperature and high pressure environment of deep wells, and is suitable for multi-section fracturing operations with long horizontal sections and multiple fracturing sections.

- Environmentally Sensitive Areas: Oil and gas development in areas with high environmental protection requirements (such as offshore, ecological reserves), no residue and non-toxic degradation products, which meets the environmental protection standards of various countries.

Q: How long does the PGA Degradable Bridge Plug take to degrade completely?
A: The degradation time is adjustable between 1-30 days, which is determined by the downhole temperature and fluid environment. Generally, it can be completely degraded within 2-10 days under normal downhole conditions (80℃-120℃). We can customize the degradation rate according to your specific well conditions.

Q: Can it withstand the high pressure and temperature of deep wells?
A: Yes. Our PGA Degradable Bridge Plug has excellent high temperature and pressure resistance, with a maximum working temperature of 200℃ and a maximum pressure-bearing capacity of 120MPa, which can fully adapt to the harsh working environment of deep and medium-depth wells, and has been verified by field tests in multiple deep wells.

Q: Is there any residue after degradation? Will it damage the formation?
A: No residue at all. The PGA material will be completely degraded into carbon dioxide and water, which are non-toxic, harmless and pollution-free, will not block the wellbore or reduce the formation permeability, and can effectively protect the formation, which is better than traditional metal bridge plugs that may leave metal residues.

Q: Can it be customized according to our well diameter and working conditions?
A: Yes. We support full customization. We can customize the well diameter adaptation (φ50mm-φ150mm), degradation rate, pressure-bearing capacity, sealing structure and other parameters according to your well diameter, downhole temperature, pressure, fracturing fluid type and other actual working conditions to ensure that the product perfectly matches your construction needs.

Q: Do you provide samples and technical support?
A: Yes. We provide free samples for you to test the product performance, and bear the sample delivery cost for bulk order customers. At the same time, our professional technical team provides 24/7 online support, including product selection, on-site construction guidance and after-sales problem solving, to ensure the smooth progress of your construction.

Q: What is the delivery time and payment method?
A: Standard products can be delivered within 3-7 days; customized products can be delivered within 15-30 days. We accept T/T, L/C, Western Union and other common international payment methods, and can negotiate flexible payment terms according to the order quantity.
