Talk:Drilling fluid

This page should at least be reverted to its previous version. The current version removes bulleted text but adds a littany of grammatical errors.68.110.203.201 (talk) 02:48, 19 September 2008 (UTC)

I think this article should be merged with the "drilling mud" article, the entry remaining "drilling mud". 81.57.36.71 (talk) 09:07, 14 April 2008 (UTC)

I agree, does anyone have a reason the two should remain separate articles? TastyCakes (talk) 15:37, 14 November 2008 (UTC)

WP:AFC submission

This text was submitted to AFC last year. Now that the backlogs are finally getting cleared out, it's been discovered again. Someone had suggested the text be merged into this article - perhaps someone better acquainted with the topic should do this. Thanks. Hersfold ^(talk/work) 19:44, 31 May 2007 (UTC)

Drilling fluids are important to lubricate and cool the drill head, prevent unwanted inflow of fluids into the well bore and to prevent collapse of the openhole and casing. It is important to balance the weight of the mud against the anticipated pressures down the well. Unexpected sudden jumps in the pressure regime can cause the inflow of fluids into the well which can lead to a dangerous blowout. Having to high a mud weight can cause loss of circulation of drilling fluids, infilling pores and damaging the drilled stratigraphy. http://www.glossary.oilfield.slb.com/Display.cfm?Term=mud%20weight

link not working

The link to Baroid Drilling Fluids Handbook existing under the references does not work.--Bramfab 10:19, 29 November 2007 (UTC)

merge

I think merging drilling fluid and drilling mud makes a lot of sense. I'm not totally convinced which should be merged into which, however, drilling mud is the much more often used term, but drilling fluid includes non liquid fluids sometimes used in drilling, like air or flu gas. Any opinions? TastyCakes (talk) 15:39, 14 November 2008 (UTC)

Yes i think it should be merged. But i think the title should be drilling fluid, which is the proper technical name. —Preceding unsigned comment added by 211.25.129.2 (talk) 01:43, 15 December 2008 (UTC)

I agree they should be merged, is there any way to have a "drilling mud" search send the user or recommend to the user that they link to "drilling fluids" such as a "key word" list?--Yesterdaysfuture (talk) 22:05, 9 January 2009 (UTC)

yes a (numbersign)redirect page would redirect the defunct page to the active one. TastyCakes (talk) 22:08, 9 January 2009 (UTC)

drilling fluid not necesarily the same

Care should be taken not to confuse what is clearly an oilfield or geo-drilling technology with the use of "drilling fluid" as a subset of "metalworking fluid" - i.e., specialised lubricant/ coolants used in machining operations. The requirements and chemistries used are quite different...

Bjtheprof (talk) 16:04, 27 March 2009 (UTC)

Hmm perhaps a note at the top referring to Cutting fluids should be inserted. TastyCakes (talk) 16:37, 27 March 2009 (UTC)

numbers

the article dont give some numbers for typical mud density --Itu (talk) 00:38, 5 May 2010 (UTC)

That would be because it's a very highly variable matter.

I've used muds up to 18.5ppg myself (that's about 2.2 g/cm^3, and about as high as you can get with barytes-based drilling muds), but that same area had piles of heamatite powder probably left from some previous "interesting well", which can go up to somewhere in the mid-20s of ppg. If you see that twice in your career, then you need to be revising your drilling practices.

I don't know the practices in the USA - not my continent - but in Europe any well that is planned to go higher than 15ppg is designated as a HTHP well, with all that that entails in arming oneself for bear. Routine operations are drilled with as-low-as-possible to decrease costs, improve drilling speeds and minimise formation damage from filtrate invasion. 11-12ppg is a common range. But you have to look at each and every section of each and every well as a separate entity. Again, European regulations call for drilling to stop any time that the rig does not have enough weighting agent on site to raise the mud system by 0.2ppg (I don't know American regulations ; I do know that Korea has no such regulation, or ignores any such regulations).

But ... I've got a question I'm looking for an answer to, and stumbled on this while searching. I may get back to tidy up the main article. One day. Aidan Karley (talk) 20:56, 17 October 2014 (UTC)

bottom hole pressures

In oil field drilling the bottom of the hole pressure is usually figured as if the hole were filled with salt water.WFPM (talk) 11:14, 20 October 2010 (UTC)

References

I think it's interesting that thousands, or hundreds of thousands, of Wikipedia articles say things like "please add inline references" or some other criticism. This article had a request to add inline citations two years ago.

If a subject matter expert sits down and writes an article like this, without lots of citations (and no original research), is it good enough for Wikipedia? The article is certainly good enough for me as a layman to learn from. —Preceding unsigned comment added by 75.146.141.142 (talk) 19:28, 7 June 2010 (UTC)

Suspended rather than dissolved

Suggest revising section on WBM to replace the term 'dissolved' with 'suspended' or something similar, as, strictly speaking, clay would not dissolve in water, but would form a suspension with appropriate mixing. Someone with closer association with the subject may have a better term. Edinfo (talk) 13:02, 15 June 2010 (UTC)

I agree, I've changed it to suspended. TastyCakes (talk) 14:39, 15 June 2010 (UTC)

Flyash

Is FlyAsh name of component used widely (like barite, brine etc) or it's just a company product name? If it's just a product name then this kind of usage is not acceptable. We see just picture of something in bag (we dont know what's inside) but we clearly see name and phone number. Also other uses in text are not acceptable. Or they are? --Blueye (talk) 18:18, 28 September 2015 (UTC)

It seems to be a generic name, see eg http://ijret.org/Volumes/V02/I08/IJRET_110208025.pdf or Fly_ash. The Crab Who Played With The Sea (talk) 19:25, 28 September 2015 (UTC)
