An Unconventional History
• Hydraulic Fracturing began in 1947 – Haliburton commercialized in 1949– Used to treat superfund ground water
• Horizontal drilling – Directional since 1934– True horizontal in the 70’s
• 1 + 1 > 2– Barnett shale in early 90’s

PA Exploration
• World’s first oil well in 1859– 350,000 conventional
• About 70,000 producing
– 2500 wells per year– Less than 5000 Marcellus
• Quadrupled state gas output
• Minimal change in well starts• Risk, reward, perception changed

Shale Gas Exploration
• Birth of a new market
• Multiple supply chain needs– Pre‐drill studies– Water re‐use and treatment– Waste disposal

Matrices
• Concentrated brines• Multi‐phase
– Drilling muds– Treatment sludges
• Heterogenous– Filter socks– Cuttings
• Natural Gas• NORM!

Analytes
• New Contaminants of Concern–Bromide–Total chloride in soil–Strontium–Dissolved gases–Radionuclides
