Silvio Berlusconi (/ˌbɛərlʊˈskoʊni/ BAIR-luu-SKOH-nee; Italian: [ˈsilvjo berluˈskoːni] (listen); born 29 September 1936) is an Italian media tycoon and politician who served as Prime Minister of Italy in four governments from 1994 to 1995, 2001 to 2006 and 2008 to 2011. He was a member of the Chamber of Deputies from 1994 to 2013, and has served as a member of the Senate of the Republic since 2022, and previously from March to November 2013, and as a Member of the European Parliament (MEP) since 2019, and previously from 1999 to 2001.

Berlusconi is the controlling shareholder of Mediaset and owned the Italian football club A.C. Milan from 1986 to 2017. He is nicknamed Il Cavaliere (The Knight) for his Order of Merit for Labour. 
The Order of Merit for Labour (Italian: Ordine al Merito del Lavoro) is an Italian order of chivalry that was founded in 1923 by King Vittorio Emanuele III. It is awarded to those "who have been singularly meritorious" in agriculture, industry and commerce, crafts, lending and insurance. It is a continuation of the earlier Ordine al Merito Agrario, Industriale e Commerciale founded in 1901. Members of the order may use the title Cavaliere del lavoro.

He voluntarily resigned from this order in March 2014. In 2018, Forbes ranked him as the 190th richest man in the world with a net worth of US$8 billion. In 2009, Forbes ranked him 12th in the list of the World's Most Powerful People due to his domination of Italian politics throughout more than twenty years at the head of the centre-right coalition.

Berlusconi was Prime Minister for nine years in total, making him the longest serving post-war Prime Minister of Italy, and the third longest-serving since Italian unification, after Benito Mussolini and Giovanni Giolitti. He was the leader of the centre-right party Forza Italia from 1994 to 2009, and its successor party The People of Freedom from 2009 to 2013. Since November 2013, he has led a revived Forza Italia. Berlusconi was the senior G8 leader from 2009 until 2011, and he currently holds the record for hosting G8 summits (having hosted three summits in Italy). After serving nearly 19 years as a member of the Chamber of Deputies, the country's lower house, he became a member of the Senate following the 2013 Italian general election.</think>

user: Why would an oil and gas exploration company utilize directional drilling in their drilling program?

assistant: There are several reasons and oil and gas exploration company would need to utilize directional drilling techniques when drilling wells. If, for any reason, a drill site is not accessible from the surface (ground level) then the drilling rig will be offset from the target. Because the drilling rig is not physically able to locate on top of the geological target the oil and gas company must use directional drilling techniques to steer the well to the target from an offset position. Examples of this could include drilling for resources under Federal land or when drilling in highly populated areas. Another reason for utilizing directional drilling techniques is to maximize hydrocarbon production. Directional drillers can turn the well-bore to intersect with the target zone at the X-Y axis, instead of only through the Z-axis. This maximizes the amount of "zone" the well-bore has access to.
