TASK DEFINITION: In this task, you are given a set of context paragraph and some supporting facts to answer a question. Your task is to generate answer for given question based on set of context paragraphs and supporting facts.
PROBLEM: Context_1 : Prudhoe Bay Oil Field is a large oil field on Alaska's North Slope. It is the largest oil field in both the United States and in North America, covering 213543 acre and originally containing approximately 25 Goilbbl of oil. The amount of recoverable oil in the field is more than double that of the next largest field in the United States, the East Texas oil field. The field is operated by BP; partners are ExxonMobil and ConocoPhillips Alaska. Context_2 : The Kern River Oil Field is a large oil field in Kern County in the San Joaquin Valley of California, north-northeast of Bakersfield in the lower Sierra foothills. Yielding a cumulative production of close to 2 Goilbbl of oil by the end of 2006, it is the third largest oil field in California, after the Midway-Sunset Oil Field and the Wilmington Oil Field, and the fifth largest in the United States. Its estimated remaining reserves, as of the end of 2006, were around 476 Moilbbl , the second largest in the state. It had 9,183 active wells, the second highest in the state. The principal operator on the field is Chevron Corporation Context_3 : Cantarell Field or Cantarell Complex is an aging supergiant oil field in Mexico. It was discovered in 1976 after oil stains were noticed by a fisherman, Rudesindo Cantarell Jimenez, in 1972. It was placed on nitrogen injection in 2000, and production peaked at 2.1 Moilbbl/d in 2003. In terms of cumulative production to date, it is by far the largest oil field in Mexico, and one of the largest in the world. However, production has declined since 2003, falling to 408000 oilbbl/d in April 2012, making it Mexico's second most productive oil field after Ku-Maloob-Zaap. Context_4 : The Tarn oil field is an oil field in North Slope Borough, Alaska, United States. It is adjacent to the Kuparuk Oil Field, Alaska's second largest oil field. Context_5 : The Round Mountain Oil Field is a large oil and gas field in the foothills of the Sierra Nevada, about 10 mi northeast of Bakersfield, California, United States. It is east of the giant Kern River Oil Field, one of the largest in the United States, and also close to the Mount Poso Oil Field and Kern Front Oil Field. With a cumulative total recovery of more than 110 Moilbbl of oil, it is the 48th largest oil field in California, but remains relatively productive with still about ten percent of its reserves remaining in the ground, according to the California Department of Oil, Gas, and Geothermal Resources (DOGGR). Context_6 : Carabobo is an oil field located in Venezuela's Orinoco Belt. As one of the world's largest accumulations of recoverable oil, the recent discoveries in the Orinoco Belt have led to Venezuela holding the world's largest recoverable reserves in the world, surpassing Saudi Arabia in July 2010. The Carabobo oil field is majority owned by Venezuela's national oil company, Petroleos de Venezuela SA (PDVSA). Owning the majority of the Orinoco Belt, and its estimated 1.18 trillion barrels of oil in place, PDVSA is now the fourth largest oil company in the world. The field is well known for its extra Heavy crude oils, having an average specific gravity between 4 and 16 °API. The Orinoco Belt holds 90% of the world's extra heavy crude oils, estimated at 256 billion recoverable barrels. While production is in its early development, the Carabobo field is expected to produce 400,000 barrels of oil per day. Context_7 : Dresser Industries was a multinational corporation headquartered in Dallas, Texas, United States, which provided a wide range of technology, products, and services used for developing energy and natural resources.

In 2001 Halliburton sold five separate, but somewhat related former Dresser non "oil patch" divisions, to an investment banking firm. Those five operations later took the name "Dresser Inc." In October 2010, Dresser Inc., was acquired by General Electric. It is headquartered in Addison, Texas.

As of the beginning of 2009, it retains 316 active wells, and has an estimated 1.4 Moilbbl of oil remaining recoverable with current technology.

Reis collaborated with drummer Tony Di Prima, bringing in Rocket From the Crypt guitarist Andy Stamets while Reis himself played the bass guitar (he is normally known as a guitarist). The band chose the name Sultans for the project and recorded an introductory EP and "Ghost Ship", both of which were released that year on Reis' newly formed Swami label. As Reis has a tradition of using different stage names or pseudonyms in his various projects, he chose to be known as "Slasher" in the Sultans, while Stamets chose the nickname "Black Flame".

Reis wrote and recorded a batch of songs in San Diego with Delta 72 drummer Jason Kourkounis. To provide vocals for the tracks Reis called in Rick Froberg, whom he had played with in Pitchfork and Drive Like Jehu from 1986 to 1995.
