Innovative Surfactant System Formulations for LNAPL Recovery:
Technology Description and Project Design Workshop

2017 MSECA Sponsors
MSECA appreciates the support of our annual sponsors in helping us to bring great education to our membership.


Program Summary:

Presented by:

Jeffrey Harwell, Ph.D., University of Oklahoma
David Alden, Tersus Environmental

Session Description:

Technology developed at the University of Oklahoma, originally focused for enhanced oil recovery at petroleum reservoirs and subsequently adapted to the environmental arena, can lower the IFT sufficiently to allow physical mobilization of residual LNAPL with the limited production of thermodynamically stable emulsions. Dr. Harwell with start this talk by focusing on the use of artfully formulated surfactant blends that reduce solubilization and simply allow LNAPLs in saturated soils to become mobile. David Alden will follow with an example surfactant flood feasibility design and cost estimation process.

Learning Objectives:

To understand the scopes, limitations, and advantages of Surfactant Enhanced Aquifer Remediation.
