The environmental and human health impacts of oil and gas extraction practices, including reservoir stimulation, are not well characterized. Although reservoir stimulation practices such as hydraulic fracturing and acidizing have been used in California for decades, detailed data and information about these practices has not been publicly available until recently. California now has requirements for oil and gas operators to disclose information about stimulation practices, including the location of wells that will be stimulated, water and chemical use, and more. What have we been able to learn and what data gaps still remain? Data and information that will be discussed include: water source and volume, chemical identity and quantity, stimulation type, well location, groundwater monitoring plans, and data quality and accuracy.
