time to look for a new pump?, page-14

GJ,
To get an idea of what kind of a pump is being deployed, have a look at this web page for Electric Submersible Pumps

http://www.slb.com/content/services/artificial/submersible/index.asp?

These things are designed to operate at the bottom of very hot wells, but are used in other applications as well, I quote from there web site
"In addition to typical applications in oil, water, and brine production, pumps are used for booster service, ballast transfer, waterfloods, direct injection, cavern storage, mine dewatering, fire protection, irrigation, and commercial water systems."

Apparently this problem has reached the ears of, and is receiving the attention of Schlumberger's CEO, so you rest assured GGW has been bleating loudly.
