HT / HS Reservoir
|
 |
APPLICATIONS » We are finding that assumptions, practices, and designs that have served us well historically are no longer valid or fit for purpose for high temperature and high salinity (HT / HS) wells. Many production chemical treatments must be re-examined carefully to ensure that they are applied properly to HT / HS wells because many assumptions and treatments that are used successfully in normally pressured wells at lower temperatures will prove inadequate in HT / HS applications and may result in considerable financial loss.

These new series of water soluble polymers have superior long-term performance at elevated temperatures and at high salinity. In some cases the initial solution viscosity with a PolyFlood Max polymer will maintain this viscosity for several months or more at hot reservoir conditions. This stable viscosity feature is one key to applying successfully polymers for long-term exposure times such as for chemical EOR. |

The thermal stability of EOR surfactants is less of an issue than for polymers. For extreme conditions reservoir temperature (> 230 F) current surfactants may degrade within the time-frame of EOR projects. For the surfactants, salinity tolerance is more important; these chemicals used in high salinity (and usually then high hardness) reservoirs must be compatible with these brines and not suffer from precipitation or become deactivated. The SurFlood HTS surfactant formulations are designed for these more challenging EOR conditions. |
