Electrical Submersible Pumps Are Very Useful Technology But With a Few Glaring Limitations

Published By : 07 Oct 2016 | Published By : QYRESEARCH

Natural resources are not only the most important source of energy, they are also limited in quantity. This factor implicates that while we look for new resources to explore, it is of utmost importance to extract the maximum out of each resource. Electrical submersible pumps (ESPs) have numerous advantages overs its competitors but none of them is bigger than its ability to drill deeper into the oil wells to extract the most out of each resource. Conversely, there are quite a few drawbacks too that is holding its popularity such as its longevity.

Significant Factors That Make ESPs Such a Useful Technology

Apart from extracting the maximum out of a resource, Electrical submersible pumps are artificial-lifts capable of carrying varying volumes, from as low as 150 B/D to 150,000 B/D. ESPs are also flexible to function under deviated wells provided they are set in a straight horizontal section. They are adaptable to required subsurface wellheads, although each must be installed 6 feet apart to maintain surface-location density. These pumps are quite safe to operate and causes very little noise pollution to the environment.

Additionally, Electrical submersible pumps are clean as far as operating at an offshore location and environmentally sensitive area is concerned.  It is also possible to install wells at the production site even when drilling is in the process at a well in the same vicinity.

Biggest Restraints in the Market for Electrical Submersible Pumps

Longevity is the single largest drawback of ESPs. These pumps can only tolerate a minimal amount of solids such as sand during production. Hard materials makes ESPs prone to damages and halt in production. Wherever electrical submersible pumps are installed, they have to function fruitfully for quite some time to be cost effective. Additionally, when operating below 400 B/D, power efficiency of EPS drops sharply and they are useless when volume rates are below 150 B/D.

Moreover, depleting oil reserves and raising population is forcing researchers to find non-conventional sources of energy and governments around the globe are encouraging those endeavors.  This factor may decrease the demand for electrical submersible pumps in future.
