Protection from wellhead erosion

Protection from wellhead erosion

WellDog has partnered with Queensland engineering firm Keli Oil and Gas Holdings to create ProSleave, a protection system to tackle erosion in wellheads.

The invention is based on resistant, ceramic sleeves inserted into the wellhead to protect against solids-based erosion at key areas.

ProSleave managing director Kevin Hadfield said the highly engineered system was simple and would greatly minimise production downtime.

“This installation can be done on new wellheads, or in a hot tap situation on an existing wellhead,” Mr Hadfield said.

“At best, oil and gas producers are adding more valves to spread the erosion, and at worst are having to completely shut the well to avoid or fix loss of containment, which is incredibly expensive.

“In many cases, production has to be halted for long periods of time.

“ProSleave uses proprietary ceramic components to protect wellheads from solids-based erosion in gathering systems.

“This is the only product of its type in the world, and we developed it specifically for Queensland.”

The company was working ‘full-tilt’ to increase its manufacturing and service capabilities to meet demand, he said.


It plans to introduce ProSleave to North America shortly after its launch in Australia.

Why bother with a workover?
