Abstract
Identification of risk, the potential for occurrence of an event and impact of
that event, is the first step in improving a process by ranking risk elements
and controlling potential harm from occurrence of a detrimental event.
Hydraulic Fracturing has become a hot environmental discussion topic and a
target of media articles and University studies during development of gas
shales near populated areas. The furor over fracturing and frac waste disposal
was largely driven by lack of chemical disclosure and the pre-2008 laws of some
states.
The spectacular increase in North American natural gas reserves created by
shale gas development makes shale gas a disruptive technology, threatening
profitability and continued development of other energy sources.
Introduction of such a disruptive force as shale gas will invariably draw
resistance, both monetary and political, to attack the disruptive source, or
its enabler; hydraulic fracturing.
Some “anti-frack” charges in media articles and university studies are based in
fact and require a state-by-state focused improvement of well design specific
for geology of the area and oversight of overall well development. Other
articles have demonstrated either a severe misunderstanding or an intentional
misstatement of well development processes, apparently to attack the disruptive
source.
Transparency requires cooperation from all sides in the debate. To enable more
transparency on the oil and gas side, both to assist in the understanding of
oil and gas activities and to set a foundation for rational discussion of
fracturing risks, a detailed explanation of well development activities is
offered in this paper, from well construction to production, written at a level
of general public understanding, along with an initial estimation of frac risk
and alternatives to reduce the risk, documented by literature and case
histories. This discussion is a starting point for the well development
descriptions and risk evaluation discussions, not an ending point.
