These are commonly known as "pump jacks". Compare the number of search results in google for pump jack and nodding horse. Pump jack is more prevelant in literature. Pump jack also describes what these devices do. They are a jack (lifting device) that pump. The title should be changed to pump jack. --129.173.105.28 03:25, 31 July 2005 (UTC)

I think "pumpjack" is more common than "pump jack" in an oilfield context. Gene Nygaard 03:37, 31 July 2005 (UTC)

The problem with either, of course, is that unlike the "nodding donkey" name, a pumpjack/pump jack is not specific to the oil industry. Gene Nygaard 03:44, 31 July 2005 (UTC)

I have worked in the oil industry for years and can attest that almost everyone uses the term pumpjack.--129.173.105.28 00:54, 2 August 2005 (UTC)

Another random person here who works in the oil industry and who has never heard the term 'nodding donkey'. I grew up in West Texas, where (in some places) pumpjacks are more dense than trees, and I've been calling them 'pumpjacks' since I was a kid. Pumpjack, pump jack -- that's what it's called. Not sure whether one word or two is the preferred spelling.

Some of the terms are probably regional. I think that "nodding donkey/horse" is more common in the northern prairies/Canada. heqs 07:09, 19 May 2006 (UTC)

Im from Alberta and everyone i know calls it a pumpjack, except some guys way way up north, they called them "grasshoppers"

[edit] A 'Rocking-horse derrick'

Has anyone else heard of these being called that? A "Rocking-horse derrick"? CaribDigita 02:20, 8 June 2006 (UTC)

No... not really... In all honesty, I'd never heard anything but "nodding donkey". 68.39.174.238 18:09, 8 August 2006 (UTC)

Here in England i grow up with them being known as "nodding donkeys".

In Wyoming and Nevada, USA, my dad, an old oil hand always called them "Jenson Jacks" or "Jensen Jacks". 70.243.166.44 04:20, 6 December 2006 (UTC)

[edit] Curious

I have zero experience in the oil industry. Just curious. Does each pumpjack have a local reservoir or are they connected by underground pipes to some main storage facility?

I mean, where does the oil go when it is pumped on each stroke?? —Preceding unsigned comment added by Weengineer (talk • contribs) 18:34, 11 April 2008 (UTC)
