The blue whale, or, as it is called, the blue whale - is perhaps the largest mammal animals on the planet. The weight of this giant may reach 200 tons and a length of more than 30 meters. Before the historic habitat of blue whales can be regarded as the entire world's oceans, they can be found in the depths of the ocean from the Arctic to the Antarctic, but at present the territory habitat of these mammals is significantly diminished. First of all, this is due to the uncontrolled whaling, which peaked in the middle of the XX century.By the 60 th years of the last century, the blue whale was virtually destroyed and its population in the world's oceans to the brink of extinction - according to scientists, in 1963 there were only 5,000 individuals. Today, the number of blue whale does not exceed 10 thousand individuals and, despite the ban on its fishing, the trend towards an increase in the populations of this mammal are very low. American scientists who conducted long-term studies of livestock blue whales, have expressed concern that the number of these cetaceans are unlikely to recover to its original dimensions. But sometime before the intense destruction, the number of blue whales was estimated at 275,000 animals! ...Now the blue whale is listed in the International Red Book and is considered the largest species of animals on Earth, which are threatened with extinction.
Equipment failure is probably the EQUIPMENT FAILURE For example, a most common type of production problem. the rod from may well, requiring special equipment called a service rig to recover chassis the hole and pumping mounted on a self-propelled unit will and has a put the well back into production. The rig is do not have a derrick, the from the include a mast and of its own. Since wells drilled in recent years the pump cases to works for removing equipment such as rods, tubing and wellbore. Another common production problem is subsurface pump failure, due in most quickly physical wear of one or more of the pump repairs. If parts. When this occurs, a service from corrosion, remove the pump, and the necessary moving tubing develops can a leak or or mechanical stresses, the service again called to the well. is removed from the hole, the damaged joint is replaced, and the tubing returned to the wellbore. If the well needs quick jolt of clean fluid to get it working again a truck mounted unit is called This unit pulls the pump up the well using its derrick and draw works. A load of clean oil is pumped down by the same unit. The pump is then reseated and the well placed on pump.
