Natural gas is an abundant, reliable and versatile fuel source that omits up to 60 percent less CO2 than coal when used for power generation. Learn more about the process of unlocking natural gas found in shale and other tight rock formations.
Before any wells are drilled, extensive surveillance is done to study the locations of the underground natural gas reservoir and the nature of the local topography, so as to ensure minimal impact of operations on the local community.
Horizontal drilling, or essentially drilling sideways, is a true testament to engineering and scientific innovation.
Hydraulic fracturing, or “fracking,” is the process of extracting oil or natural gas from shale reservoirs. Hydraulic fracturing is a time-tested, proven technology that has been safely used in more than a million wells worldwide since the 1940s.
Hydraulic fracturing fluid is typically comprised of approximately 98 to 99.5 percent water and sand and 0.5 to 2 percent chemical additives.
A properly designed and constructed oil and gas well is essential to protecting the water table and ensuring successful production.
The water used in unconventional resource development and hydraulic fracturing typically comes from surface or groundwater sources.
ExxonMobil’s report to shareholders outlines how the company assesses and manages risks associated with developing unconventional resources, including through hydraulic fracturing.
