At the time of it's popularity neither of these was readily available in pocket format, certianly not for a few bucks. This is nearly useless. At the time (1930? 1960? 3:00 in the afternoon?) of it's (Wrong pronoun, and what does 'it' refer to?) popularity neither of these (Neither of what?) was readily available in pocket format (Is drilling equiment expected to be available in pocket format?) , certainly not for a few bucks (Is drilling equipment expected to be available for a few bucks?)

Slide Rules don't do trig to the best of my knowledge. This is patently untrue, as even a casual perusal of the article on slide rules will demonstrate. Phrasing is also decidedly unencylopedic —Preceding unsigned comment added by 216.51.227.28 (talk • contribs)

There is a simpsons episode in which this occurs. It could do with mention. ―BenFrantzDale 15:37, 1 February 2006 (UTC)

[edit] Slant drilling

I dissagree with: "Directional drilling (sometimes known as slant drilling outside the oil industry)"
Slant drilling is rather drilling with a rig that has a derrick that is oblique, that is not vertical. Slant drilling is used in the oil industry as well, and is differnt from directional drilling because of the technique used to achieve deviated holes: slant starts with an oblique angle of incidence, directional drilling uses a drilling motor with a bent.Qyd 03:53, 15 February 2006 (UTC)

Actually, the art of directional drilling involves much more than the simply use of a motor with a bent. In fact, it takes in account the knowledge of the formation you´re drilling into, specially in a highly developed field. In some cases, you may en up "sliding" the string in a zone where the formation dip can do the entire job, or even worse, that formation dip would take the bit anywhere... Talking about the "Slant" term, is some times used to describe "J" type wells, that´s buliding some inclination and then hold a tangencial section. Nickmr, June 2006


I am currently logging a horizontal well. 7500ft. down at 90 degrees 9900 TD , Drilling in the Barnett Shale in North Central Texas. nothing slanted about it ! R.Rhyne. Johnson Co. Texas 9/12/06

Herbm 20:10, 30 December 2006 (UTC) Agree AND Disagree with the criticism of "slant hole": As a former Directional Driller, the term "slant hole drilling" is seldom, if ever, used by professionals to describe such techniques and wells, but it is a popular term among the general public even if incorrect, and even though it is certainly not the proper technical term.

[edit] Kuwait

Apparently, slant drilling from Kuwait into Iraqi territory was a major cause of the 1990 Iraqi invasion. Can anybody elaborate on that? —Preceding unsigned comment added by 86.40.140.72 (talk • contribs)

Herbm 20:16, 30 December 2006 (UTC) It is widely reported that this was a COMPLAINT given by Saddom Hussein and the Iraqi government (along with the claim that Kuwait was really just a province of Iraq) -- but anyone familiar with directional drilling techniques, especially of the time, would know that such claims could hard justify a war, especially a full scale invasion of Kuwait: Any such well would have needed to be very close to the Iraqi border and could hardly have ever penetrated more than a mile or bit more into Iraqi territory. Any wells using the most advanced technology would have been readily apparent due to the special equipment and special personal required, the more so as the deviation angle and vertical distance of the well increased.

[edit] Article

The article is almost entirely history of the process. How about the actual mechanics of it, why it is done, how it compares to traditional (vertical) drilling etc? 70.113.93.13 01:09, 22 November 2006 (UTC)

[edit] Would it hurt to add a "Working Principle" section?

The article burns up a lot of wordage explaining how things evolved and how the technology was used, but it could do a better job of explaining how it actually works. Landroo 19:07, 25 July 2007 (UTC)
