Vigor develops dissolvable bridge plug for high temperature and pressure

China Vigor Drilling Oil Tools and Equipment Co., Ltd. has announced the development of a new type of dissolvable bridge plug engineered to perform reliably in high-temperature and high-pressure (HP/HT) downhole environments.

The company states that traditional metal bridge plugs often exhibit instability at temperatures exceeding 120°C, limiting their application. Vigor's research and development team addressed this challenge by selecting magnesium-aluminum alloy materials and optimizing the plug's structural design.

This HP/HT dissolvable bridge plug is designed for applications such as multi-stage fracturing, where improved pressure resilience and accelerated dissolution rates can enhance operational efficiency. The company reports that the plug provides a reliable seal and is constructed using specialized manufacturing processes to ensure stability in demanding conditions.

The dissolvable bridge plug is available with customizable parameters, including temperature rating, chlorine index, pressure bearing capacity, and dissolution time. China Vigor Drilling Oil Tools and Equipment Co., Ltd. focuses on manufacturing downhole tools and equipment to assist clients in reducing oil and gas exploration, production, and completion costs.
