The Washover Pipe is an essential tool for performing washover operations, primarily used to free stuck pipes, tools, and equipment in the wellbore. Washover operations can effectively relieve various sticking accidents, ensuring continued drilling or workover processes.
In addition to its rotary washover function, it is also capable of performing sand washover, salt washover, hot washing, and deblocking operations, making it a versatile solution for downhole obstruction removal.
✔ Highly Effective Stuck Pipe Recovery – Frees drill pipe, tubing, casing, or other tools lodged in the wellbore.
✔ Versatile Functions – Supports rotary washover, sand washover, salt washover, hot washing, and deblocking.
✔ Efficient Wellbore Cleaning – Clears sand, salt, debris, and blockages to maintain smooth well operations.
✔ Compatible with Various Well Conditions – Suitable for oil, gas, and geothermal wells.
✔ Durable & Reliable – Designed for high-performance under extreme downhole conditions.
🔹 Stuck Pipe Remediation – Used to free drill pipe, tubing, and casing stuck due to differential sticking, mechanical sticking, or wellbore collapse.
🔹 Debris Removal – Helps remove sand, salt, and scale buildup in the wellbore.
🔹 Wellbore Cleaning – Ensures unobstructed passage for downhole tools by eliminating blockages.
🔹 Workover & Well Intervention – Essential for maintaining and restoring well productivity.
