Vent leaks can occur today or years after completion. Both problems are of immediate concern to environmentally minded oil and gas resource companies.
Cement Enhancement Tool®
To prevent, solve and eradicate surface casing vent leaks in a cost effective manner.
Excellent for loss circulation zones.
Reason:Vent leaks occur primarily because:
An immediate cause of vent leaks is that, as cement loses its hydrostatic head, gas can migrate.
A long term cause is that cement can break down due to production vibration and temperature changes. This may result in gaps between cement and casings and gas under pressure will find the resulting fissures.
