The United States has almost 1 million oil producing wells, and most require the use of an artificial lift system. There are various methods of artificial lift which are utilized to increase pressure within the reservoir to push oil to the surface. This allows operators to enhance production and extend well life.
One of the most efficient and reliable methods of artificial lift for moderate to high volumes of fluids from well bores is through use of electrical submersible pumps (ESP). It is important for ESP systems that every component stands up to the rigors of high pressures, high temperatures and direct contact with the well fluids and contaminants common in oilfield environments.
