Home CleanSuite™ Technologies Fluids Disclosure Fracturing 101 Glossary

Halliburton pioneered fracturing technology in the mid-1940s, and has always supported and complied with state and federal requirements promoting disclosure of additivesthat typically comprise less than one-half of 1 percent of our solutions.

Much of this information has been available to the public for quite a while – although it tends to be hard to find and even tougher to understand. This site aims to change that:by naming the additives in our fracturing solutions, listing the constituents, and explaining some of their other, more common household and industrial uses.

We tailor our fracturing fluids to different geologies, so the composition will vary by location. Over time, we'll be populating these pages with information from every state inwhich our services are in use. For now, we present information on several different fluid systems from Pennsylvania, a state where fracturing technology has alreadygenerated thousands of jobs for residents and billions in annual revenue for the state and local landowners.

Pennsylvania Water Frac Formulation

The Marcellus Shale is a 390-million-year-old rock formation that underlies more than 34,000 square miles of Pennsylvania, in addition to extending into a numberof neighboring states.

Estimated to house hundreds of trillions of cubic feet of natural gas, the Marcellus shale play is currently under development primarily in the southwest and north-central regions of the state. Typical fracturing operations in Pennsylvania take place at a depth of between 4,000 feet and 8,500 feet below the ground surface.
