Halliburton's interactive site that shows the history of fracking, and how the process works.

Launched by the Independent Petroleum Association of America (IPAA) in 2009, Energy In Depth (EID) is a research, education and public outreach campaign focused on getting the facts out about the promise and potential of responsibly developing America’s onshore energy resource base – especially abundant sources of oil and natural gas from shale and other “tight” reservoirs across the country. It’s an effort that benefits directly from the support, guidance and technical insight of a broad segment of America’s oil and natural gas industry, led in Washington by IPAA, but directed on the ground by our many affiliates — and IPAA’s more than 6,000 members — in the states.
