Welcome to FracFocus 2.0! We're excited about our latest upgrades designed to dramatically enhance the site's functionality for the public, state regulatory agencies and industry users. Our user-friendly 'Find A Well' chemical disclosure registry now includes more extensive search options.
FracFocus continues to evolve and expand, adding more participating companies and reported wells from across the country. Our continued success is the result of nationally recognized organizations working with state governments and the oil and natural gas industry to provide public transparency.

This technique uses a specially blended liquid which is pumped into a well under extreme pressure causing cracks in rock formations underground. These cracks in the rock then allow oil and natural gas to flow, increasing resource production.

Casing is the multiple layers of steel and cement inside the drilled hole used to protect water aquifers. The specific length, thickness, strength and composition of casing is regulated at the state level.

Groundwater Protection: Priority Number One
Oil and natural gas producers have stringent requirements for how wells must be completed. The genesis of these requirements is water safety.
Casing is the first line of defense used to protect freshwater aquifers.

How much water is used in hydraulic fracturing?
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 million gallons of water.

What is Hydraulic Fracturing?
Hydraulic fracturing, commonly referred to as fracing, is the process of creating small cracks, or fractures, in underground geological formations to allow natural gas to flow into the wellbore and on to the surface where the gas is collected and prepared for sale to a wide variety of consumers.
During the fracing process, a mixture of water, sand and other chemical additives designed to protect the integrity of the geological formation and enhance production is pumped under high pressure into the shale formation to create small fractures.
The newly created fractures are “propped” open by the sand, which allows the natural gas to flow into the wellbore where it is collected at the surface and subsequently delivered to a wide range group of consumers. Read more...
