Stable crosslinked foaming gel
Effectively seal natural fissures and fractures, and stop the unwanted flow of gas and water.
Water and gas conformance service
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.
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.
