Water and gas conformance service
Manage or shut off water and gas production with application-specific permeability modifiers, chemical blocks, or cements.
To control unwanted gas or water production and increase oil production, FoamSEAL stable crosslinked foaming gel is designed to create a seal in gas-producing zones, effectively trapping the gas.
By producing a high-quality foam capable of invading the gas zone and sealing it, the gel stops gas flow toward crude oil channels. A high-quality (60% to 80%) foam is generated using foaming agents selected for specific well conditions. The stability of the foam makes it particularly well-suited for use in naturally fissured or fractured carbonate and sandstone reservoirs.
FoamSEAL gel is not sensitive to crude oil or shear, and it also works to minimize damage in crude oil-producing zones.
Working time of the FoamSEAL gel is managed by adjusting the activator concentration. Setting time can be controlled from 1 to 24 hours for reservoir temperatures between 100 and 300 degF [38 and 149 degC].
AllSeal water and gas conformance service is an engineered approach to stopping unwanted water or gas production.
Production in mature offshore Mexico fields is mostly driven by gas injected from surface. With time, injected gas flows directly through natural fractures in the low-pressure carbonate reservoirs, leaving oil trapped in the low-permeability matrix and reducing crude production.
