California Passes Fracking Regulation

Jerry Brown Delivers California State Of The State Address

California is leading the way on fracking legislation, with the passage of California Senate Bill 4, frackers in California are now required to follow a new set of rules on disclosure of their fracking fluids and the impacts they have on the environment. The law requires that fracking operators publish the proportions, quantity, and chemical names of all of the components of their fracking fluid, and to provide free testing of water sources nearby the fracked wells. The law also requires disclosure on how much wastewater is produced, its chemical composition, and how it is disposed off.  A particularly good measure will be a requirement for the monitoring of groundwater before, during, and after fracking operations.

The law is being attacked by both the fracking industry and environmentalists. Environmentalists see the law as too weak. One group sent a petition to Governor Brown of California, asking him to pass a ban on all fracking in the state. Industry groups have claimed that this bill will make it harder to frack and slow down growth in the state, threatening growth in California.

Fracking can cause contamination of aquifers and small earthquakes, as multiple studies have concluded. However, there has yet to be a comprehensive scientific study looking at large number of wells on the effects of fracking on ground water and seismic activity in a broad area. By making testing mandatory this law could provide clear and definitive data on fracking and foster a much better understanding of the practice. While some my say that a ban is necessary, it perhaps premature before a comprehensive scientific study has been conducted. Should the data  this law will provide make it clear that fracking is an imminent danger to water quality, it would then be appropriate and necessary to pass a law banning the practice entirely.

ReThink Energy Florida

ReThink Energy Florida is a Florida-based grass roots organization that seeks to to engage and educate Floridians on energy and environment issues to promote a more sustainable future. The provide tools, science based information, and services to help people educate themselves and to create a cleaner and safer energy future for Florida.

Halt the Harm

Halt the Harm is a network of people spread across the United States working towards reducing and eliminating the harmful effects of fracking. Their website is full of articles about peer reviewed scientific studies being conducted on fracking and its health effects on people, and is an excellent resource for information on fracking. Anyone interested in learning about hydraulic fracturing and the effects its having in America should go check out their website at

Overview of Shale Formation Exploitation

The History of Commercial Fracking

Commercial Fracking began in the early 2000s in Texas in the Barnett Shale.  There are three types of product that come out of shale formations, natural gas, tight natural gas, and light tight oil. Natural Gas and Tight Natural Gas are only distinguished by the geological formation they are found in. Light Tight Oil is defined by it being found in low permeability formations such as carbonate and shale formations. The identification of tight natural gas as a separate production category began with the passage of the Natural Gas Policy Act of 1978 (NGPA).  This was done to remove tight natural gas from existing regulatory frameworks and allow its price to be purely market determined and encourage increased exploitation.

There are two key developments that make fracking possible, hydraulic fracturing and horizontal drilling. Hydraulic fracturing is the injection of high pressure fluids and chemicals to break up formations and permit a flow of natural gas to the surface  Horizontal drilling is the key technology to making fracking commercially possible. Tight oil formations by their nature do not give up their contents easily. They must be broken up by hydraulic fracturing to release oil and natural gas. Horizontal drilling allows a far larger area to be fracked from a single borehole, meaning far less expense compared to previous vertical drilling tech which required many wells to be drilled to access the same formation.

Where is the Oil and Gas Found

Shale formations in the United States of America are concentrated in Texas and the Appalachian basin. The Bakken shale is also of note, as its proximity to the proposed Keystone XL Pipeline is central to its profitability by reducing its transport costs to the refineries on the east coast and in Texas.  The United States is ranked second in light tight oil and fourth in tight natural gas reserves.

The graphs below illustrates the shale formations in the United States and where the majority of fracking is being conducted.


Shale Production: Reserves and Costs of Production

Currently only four countries are producing from shale formations. Two types of product can be produced from shale oils, natural gas and light tight oil. Natural gas is an actual gas that we familiar with, heating our homes and generating electricity, Light tight oil a grade of oil that is trapped in shale formations, and is one of the higher quality and more flammable types of oil. The United States of America, Canada, China, and Argentina are the four current commercial producers of shale natural gas and oil.  The United States produces the vast majority of both, with Canada in second. New production from shale formations is coming online in Algeria, Australia, Colombia, Mexico and Russia.

The graph below illustrates relationship between prices and the size of reserves. Reserves actually refer to the amount of oil or natural gas that it is profitable or cost effective to recover at current prices. Shale natural gas and tight oil is significantly more expensive to recover than conventional oil. So as the price goes down the size of shale reserves actually decreases. At current prices, $45 – $50 the Canadian tar sands are no longer viable to produce. Oil prices to be $70 – $75 to make it worthwhile to produce. As well much of the shale gas production in the United States is no longer profitable to produce at current oil prices.
