Manage water and gas production with flexibility to match your goals and strategies

Water production characteristics and causes vary significantly from well to well, and water strategies vary among operators and locations. To accommodate this variety, the AllSeal water and gas conformance service integrates a wide portfolio of shutoff technologies from relative permeability modifiers (RPMs) and temporary chemical blocks to permanent cements.

We select the right solution based on your field and operational requirements, reservoir characteristics, economic constraints, logistics, and best practices gathered over decades of work around the world. The result is a fit-for-purpose solution matched to your particular well or situation.

The wide portfolio of shutoff technologies enables engineers to match reservoir properties, customer economics, and logistics to ensure successful operations.

Reduce or eliminate the costs of lifting, handling, hauling, and disposing of water. Extend your well's producing lifetime, improve environmental stewardship, and increase hydrocarbon recovery.

Improve oil recovery with engineered gas control 

Gas breakthrough is common in naturally fractured oil reservoirs or through leaks in cement or casing. Increasing gas production reduces crude oil production. Eventually the well becomes uneconomic, leading to shutting in the well despite its potentially recoverable reserves.

AllSeal service provides engineered alternatives to continue or restore production to these wells and recover otherwise lost reserves, which can significantly improve the economics of operating the field.
