Directional drilling (or slant drilling) is the practice of drilling non-vertical wells. It can be broken down into three main groups: Oilfield Directional Drilling, Utility Installation Directional Drilling (or H.D.D. or Horizontal Directional Drilling) Directional boring, and SIS (surface In Seam), which horizontally intersects a vertical well target to extract coal bed methane.

Many prerequisites enabled this suite of technologies to become productive. Probably, the first requirement was the realization that oil wells, or water wells, are not necessarily vertical. This realization was quite slow, and did not really grasp the attention of the oil industry until the late 1920s when there were several lawsuits alleging that wells drilled from a rig on one property had crossed the boundary and were penetrating a reservoir on an adjacent property. Initially, proxy evidence such as production changes in other wells was accepted, but such cases fueled the development of small diameter tools capable of surveying wells during drilling.

Peter "Pete" Hoekstra (born October 30, 1953) is a former Republican U.S. Representative for Michigan's 2nd congressional district who served in the House from 1993 until 2011. He was an unsuccessful candidate for Governor of Michigan in 2010 and is running for the United States Senate against Debbie Stabenow in 2012.

Born in Groningen, The Netherlands, he moved to America with his parents at the age of three. He received a B.A. in political science from Hope College in 1975 and an M.B.A. from the University of Michigan's Ross School of Business in 1977. He then joined office furniture maker Herman Miller and remained there for 15 years, eventually becoming vice president of marketing.

In 1992, Hoekstra made his first bid for public office in the 2nd District. The district, previously the 9th, had been represented for 26 years by Guy Vander Jagt, longtime chairman of the National Republican Congressional Committee. Hoekstra rode his bicycle across the district, charging that Vander Jagt had served in Congress for too long. He scored a monumental upset, winning by almost six percent. This primary win was tantamount to election in the 2nd district, the "most Republican" district in Michigan (Republicans have held the district for all but four years since it was created in 1873). (Hoekstra continues to ride his bicycle across the district every summer, and biked across the state for his gubernatorial campaign).

Ronald Ernest "Ron" Paul (born August 20, 1935) is an American politician who has been the U.S. Representative for Texas's 14th congressional district, which includes Galveston, since 1997, and a three-time candidate for President of the United States, as a Libertarian in 1988 and as a Republican in 2008 and currently 2012. He is an outspoken critic of American foreign and monetary policies, including the Military–industrial complex and the Federal Reserve, and is known for his libertarian-leaning views, often differing from his own party on certain issues.

A native of Pittsburgh, Pennsylvania, Paul is a graduate of Gettysburg College and Duke University School of Medicine, where he earned his medical degree. He served as a medical officer in the United States Air Force from 1963 until 1968. He worked as an obstetrician-gynecologist from the 1960s to the 1980s, delivering more than 4,000 babies. He became the first Representative in history to serve concurrently with a child in the Senate when his son Rand Paul was elected to the United States Senate for Kentucky in 2010.
