Hydraulic Fracturing Timeline
- Halliburton performs first experimental fracturing operation.
- Safe Drinking Water Act is signed into law (by the EPA) however, this law doesn’t regulate hydraulic fracturing.
- First exploration work takes place in Barnett Shale.
- Horizontal completions introduced in tight sandstone.
- EPA disregards the Legal Environmental Assistance Foundation’s (LEAF) petition and determines that hydraulic fracturing does not fall within the definition of “underground injection” under the SDWA.
- EPA’s Memorandum of Agreement (MOA) to remove diesel from fluid systems used in wells.
- The Barnett Shale development begins.
- Marcellus, Woodford, Fayetteville, Haynesville shale discoveries begin.
- The first exploratory well is drilled within the Marcellus shale.
- Energy Policy Act (EPACT) excludes hydraulic fracturing as an underground injection; hydraulic fracturing still not regulated by the EPA.
- Marcellus shale natural gas output reaches 1 billion cubic feet a day.
- Eagle Ford Shale discovery begins.
- The House Appropriations Committee request additional studies from the EPA.
- EPA draft report notes water contamination in Pavillion, WY, finding methane, benzene, and other organic compounds; however, these wells are unusually shallow and cannot be generalized to all fracking wells.
