Hydraulic fracturing is not new, and has been used safely and effectively for more than 60 years. During that time, more than one million wells have been completed using hydraulic fracturing.
The content of hydraulic fracturing fluid is adapted to the geological conditions of each well site.
Before any wells are drilled, extensive surveillance is carried out 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.
The geology of every unconventional gas reservoir is different, making some more accessible (and potentially more commercially viable) than others.
In addition to utilizing sound operational practices to ensure wellbore integrity and reduce operational risks, responsible extraction of unconventional gas means that industry aims to build well sites that leave as small a surface footprint as possible over the shortest period of time possible, so as to minimize the impact upon local communities.
