Directional drillingDirectional drilling (or slant drilling) is the practice of drilling non-vertical bores. It can be broken down into four main groups: oilfield directional drilling, utility installation directional drilling, directional boring (horizontal directional drilling - HDD), and surface in seam (SIS), which horizontally intersects a vertical bore target to extract coal bed methane. Many prerequisites enabled this suite of technologies to become productive.
1980s oil glutThe 1980s oil glut was a significant surplus of crude oil caused by falling demand following the 1970s energy crisis. The world price of oil had peaked in 1980 at over US35perbarrel(equivalentto per barrel in dollars, when adjusted for inflation); it fell in 1986 from 27tobelow10 (to in dollars). The glut began in the early 1980s as a result of slowed economic activity in industrial countries due to the crises of the 1970s, especially in 1973 and 1979, and the energy conservation spurred by high fuel prices. White phosphorus munitionsWhite phosphorus munitions are weapons that use one of the common allotropes of the chemical element phosphorus. White phosphorus is used in smoke, illumination, and incendiary munitions, and is commonly the burning element of tracer ammunition. Other common names for white phosphorus munitions include WP and the slang terms Willie Pete and Willie Peter, which are derived from William Peter, the World War II phonetic alphabet rendering of the letters WP.
President of IranThe president of Iran (Rayis Jomhur-e Irān) is the head of government of the Islamic Republic of Iran. The president is the second highest-ranking official of Iran after the Supreme Leader. The president is required to gain the Supreme Leader's official approval before being sworn in by the Parliament and the Supreme Leader has the power to dismiss the elected president if he has either been impeached by Parliament or found guilty of a constitutional violation by the Supreme Court.
Fateh-110The Fateh-110 (فاتح-۱۱۰ "conqueror"), also known as NP-110 is an Iranian solid-fueled surface-to-surface ballistic missile produced by Iran's Aerospace Industries Organization since 2002. It is single-stage, road-mobile and can carry high-explosive warhead up to 500 kg. It was developed into four generations successively improving range and accuracy. In the latest version, it has a range of 300 km and a "pinpoint accuracy" (a CEP below 10m). The Fateh-110 was developed from Iran's Zelzal-2 unguided artillery rocket essentially through adding a guidance system.
Preventive warA preventive war is an armed conflict "initiated in the belief that military conflict, while not imminent, is inevitable, and that to delay would involve greater risk." The party which is being attacked has a latent threat capability or it has shown that it intends to attack in the future, based on its past actions and posturing. A preventive war aims to forestall a shift in the balance of power by strategically attacking before the balance of power has had a chance to shift in the favor of the targeted party.
Preemptive warA preemptive war is a war that is commenced in an attempt to repel or defeat a perceived imminent offensive or invasion, or to gain a strategic advantage in an impending (allegedly unavoidable) war shortly before that attack materializes. It is a war that preemptively 'breaks the peace'. The term 'preemptive war' is sometimes confused with the term 'preventive war'. The difference is that a preventive war is launched to destroy the potential threat of the targeted party, when an attack by that party is not imminent or known to be planned.
