Yes. Since 2015 a data download in SQL format has been available on FracFocus. As of 2017 an additional data download in .csv format became available.

The most likely reasons are that either the wells were fractured before January 1, 2011, or they have not yet been entered into the system. Only wells fractured after January 1, 2011, will be entered into the system. Please keep checking back, as wells are added on a daily basis.

The name of the operator on the well list is based on the name used to register the company in the FracFocus system. However, companies sometimes operate through subsidiaries. For example Anadarko Petroleum Corporation purchased Kerr McGee and still operates wells under the Kerr McGee name. Regardless of the name of the operator on the fracturing record the operator name on the list reflects the name of the FracFocus participating company.

It comes from many sources including surface water bodies such as ponds, lakes, and streams, municipal authorities, groundwater wells, and 'produced water' (water that comes to the surface during oil and gas production).

One of the best glossaries of oil and gas terms is available on the web through Schlumberger Inc. (https://glossary.oilfield.slb.com/) You can use the alphabetical listing to select the first letter of the term you are looking for and scroll through the list of terms to find it. This site contains over 4600 oil and gas related terms.

Hydraulic fracturing, commonly referred to as fracking, is the process of creating small cracks, or fractures, in underground geological formations to facilitate the flow of natural gas to the wellbore.

Fracturing fluids can enter a fresh groundwater zone if there is sufficient bottom hole pressure to raise the fluid level from the fractured zone to the fresh groundwater zone, and there is a conduit through which the fluid can flow such as an open space between the casing and the formation. Fluids may also enter fresh groundwater if there is a hole in the casing above the depth of the groundwater zone and the cement outside of the casing is not adequate to prevent fluid flow between the casing and the formation. Under normal circumstances hydraulic fracturing fluid is confined to the inside of the production casing, the formation being treated and nearby formations.

All chemicals that are used to hydraulically fracture a well except for those that are being held as trade secrets.

This varies from well to well and depends upon the well configuration (vertical or horizontal), the number of stages fractured, and the specific characteristics of the formation being fractured. In vertical wells with a single fractured stage it is not uncommon to use less than 50,000 gallons of water during a fracture job, while a multi interval fracture job in a horizontal well can use several to tens of millions of gallons of water.

Chemicals are used for many purposes in hydraulic fracturing. Some chemicals are designed to inhibit bacterial growth. These are called biocides. Others make fluids flow down the casing more easily. These are called friction reducers. Without these and other chemicals, the effectiveness of the fracturing job would be limited.

It depends upon the zone being fractured.

It depends on the state. To determine if your state has a testing requirement you should contact your state oil and gas agency. Contacts for these agencies can be found at www.gwpc.org.

Water acts as the carrier fluid for the chemical additives and propping agents (typically sand) that are used to fracture the producing formation.
