During the extraction of oil fields, numerous factors can worsen the efficiency of down hole pumping.
Both the gaseous and foamy produce and the solid material content of the produce can affect the efficiency of abstraction. In many cases, this makes the use of sucker rod pumps impossible, and it is more difficult to utilize the tubing pipes, too. The decrease in production does not only result in loss of revenue, but the frequent costs of well repairs also have negative effects on production.
