Challenge

EFD Field Trials

Texas A&M Marcellus

Shale Brine Re-Use

Deliverables• Identify optimal treatment techniques for ultra-

high brine concentrations

• Provide information to community leaders

Status• Current field trials in New York• A&M Separation Sciences pilot testing new

technology• Creation of new Analytical Services Roundtable
