Oil rigs seem to be capable of drilling holes inches in diameter

How do they do this and what does the drill head look like?

The tool pusher has a display of the weight of the drill string and
keeps the force on the drill bit at the optimum level. Also the first
few joints of pipe behind the drill are drill stem, really heavy wall
stiff pipe. Not sure of how they control the curve now, but do know
that the launch computer NASA used for the moon missions was the RCA
110A. A somewhat upgraded
version of the RCA 110 which was made to control oil well drilling. So
much for NASA's vaunted technical advances in computers.

Oilwells are drilled with predetermined goals in mind. The target strata is
not always right under the oil rig. Hence, they use "directional drilling"
to make the bit go in the direction they want it to. That way, they can
puncture several levels of strata with one well to recover as much oil as
they can.

Directional drilling is achieved in many ways. It is far to complicated to
explain here in a few paragraphs. Google it and read away. Basically, it
is just a way to change the direction of a bit to hit a known reserve.
Modern advances allow drillers to make sharper turns. A drillstem is made
of steel, but anything thousands of feet long has flex in it.

Drill bits come in hundreds of sizes and configurations. Some have no
rolling bits on them. Others have rolling cutting wheels on them like the
ones you see on mining equipment. They come in all sizes.

Hughes Tools was innovative in the oil industry. NO ONE could purchase a
Hughes Tool Bit. You could only rent them. That way, there was absolutely
no question as to ownership. When one went dull or was damaged or lost, you
got another.

Google for oilwell drill bits, and read on.

I imagine that has led to some pretty heated discussions (and beyond)
when someone's drill hole ends up under the next door neighbor's property.

Or, am I wrong in assuming that one's oil and mineral rights extend down
to the center of the earth?

And what about draining the oil out of a strata which extends under
someone else's property - through a drill hole that's totally under yours?

More than heated discussions!!! There is a lot of stuff happening in the
gas fileds and oil patches of the world. I have worked with guys who used
to be on the oil rigs. Even in mild little Canada it was not unusual to
have a rifle handy for target practice. Spys would camp out in the bush to
watch the drilling of competing rigs. A glint of binocular light would
invite a few shots up onto the hillside to discourage visitors.
I have seen wanted posters for stolen drill bits at gas stations in Northern
Alberta. A bit is worth many thousands and a valuable commodity to be sold
quickly and put down a hole .... no questions asked.

As someone suggested, do a Google search. I think you will find the

Yeah, that and a bit more.

Iraq didn't like it and invaded Kuwait because of angle drilling. That
and the fact they were going broke from fighting the Iran/Iraq war.
Saddam had successfully sacked Kuwait of its treasure before we got
there.

http://www.gannettonline.com/gns/saddam/part1-1.html etc.

"By 1989, U.S. war planners were starting to create scenarios with
Saddam as the leading threat in the Middle East. But as late as
January 1990, a National War College report concluded, "Baghdad should
not be expected to deliberately provoke military confrontations with
anyone. Its best interests now and in the immediate future are served
by peace." The following summer, a cash-strapped Saddam accused Kuwait
of "angle" drilling into its vast southern Rumaila and Zubair oil
fields and invaded its neighbor to the southeast.

The United States could overlook Saddam's war crimes, but threatening
the flow of oil was unacceptable."

At this point in time in the metro areas it would be highly unusual for
someone to have their own mineral rights here in Oklahoma. Possibly some of
the more rural areas where the land has been in someones family for some
time. I have realatives that have property that is in the famous Anadarko

statehood. And, your comment is 100 per cent correct. Where bouts are you in

"Truth exists; only falsehood has to be invented."

On a much smaller scale than drilling for oil, such as in placement of
underground data or power cables or even water lines, a spoon shaped bit is
often used. A locator above grade can detect where the bit it, and if they
stop rotation and just push it for a ways, it will turn away from the bottom
side of the spoon. Then they can start rotation again and continue in a
straight line. Pretty common around places anymore for this type of stuff.
Much cheaper and faster than digging up a street or runway just because you
need to get some cable or pipe under it. They bore where they need to go,
and then when they start extracting the drill string, they can pull pvc or
poly pipe back through the hole they just bored.

It gets complicated, but the mineral rights in tracts are of a vertical
nature. So, you can't like tunnel into your neighbor's property. I don't
know what happens when a reserve lies on a boundary line, and as pumping
occurs, the oil may come from your lease or an adjoining one. Like you say,
lawyers do that stuff.

I worked in the oil patch in Alberta in the 1960's & 70's. At that time
directional drilling was expensive and uncertain. Straight drilling was done
by using very heavy "drill collars" at the bottom of the drill string. The
bits were usually three steel cones with carbide buttons on them.The cones
were mounted on bearings with the base of the cones just off the centre line
of the drill and the point of the cone facing outward. Drilling mud was
pumped down the centre of the drill string,and the entire string was
rotated. The buttons on the bit broke up the rock and the chips were flushed
up the annulus between the hole and the drill string. This mud was allowed
to run over a "shale shaker" which separated any large chips. The mud was
recirculated continuously. After a while the bit wear and drilling would
slow. This meant that the entire drill string had to be pulled out,
unscrewed into 90 ft sections and stacked on end in derrick. In those days
the deepest holes in Alberta were about 17,00 ft. It could take over 24
hours of heavy ,dirty work to replace a bit so bit quality was paramount.
Directional drilling has matured enormously since then so I'm not familiar
with present procedures

I also worked on rigs in Alberta in the 70's . Did lots of deep hole
directional drilling . Certainly in those days it was anything but
hi-tech . Three kinds of bits . Diamond used only when pulling core
samples . Toothed bits when the substrata was soft rock and button bits
when the rock was harder . When passing through strata the wrong style
bit pretty much stops progress so you have to pull the entire pipe out
and switch them . I never got as deep as 17,000 but 13,000 took about 17
hours round trip . Dangerous time . Every time the pipe is pulled a long
metal rod is dropped down the center of the drill stem . Inside is a
small compass and a point the punctures it to show the compass heading
at the bottom of the hole . If drilling is going smoothly and the pipe
is not pulled often the rod/compass is dropped down connected to a sand
line after it hits bottom it is winched back up before drilling can
proceed . If the bit has wandered to the right heading heavy thick pipes
(collars) are added right behind the bit to hold it at the desired
course . these do not flex so bore straight . In addition every so often
a specialty outfit is brought in with a contained compass and a camera .

Yep - not only can the drills be controlled, but they can be driven down riverbeds that
are thousands of feet below and running in a dip or strike or both directions.

In other words, If California wasn't so picky and not in my back yard after I moved here -
A rig in an inland valley could be drilling the oil in the oil beds off the coast.

In West Texas they found that many of the wells were taping into sand lanes or river beds
of long ago flooding waters. The well either side would be dry. Schlumberger discovered
this (IIRC) and how to gather the oil down stream and not using verticle holes.

Slant drilling was once against the law. Now it saves a lot of time, money and pollution.
Slant is the old way of diagonal or slant drilling into a neighbors pool that you can't
hit going verticle.

Nice note Ken -

I knew a fellow scientist at SLB (another lifetime and a better brain I tell you!)
he was working on and broke it - how to data log with tools in real time while
drilling ! - Normally a bit is extracted and then the tool set is dropped down-hole.
This took time and time is money! - Besides - think of having an expensive crew there
during a extract and drop and pull - or while you drill - the convince won. Money
was not considered - just tell me today if I have half a change of oil or if
that pinch out sand group was ever touched... Real time is great for joy stick control
(almost :-) ) I know how he got by the signal - one "wire" is the drill stem/pipe system...

I worked in the oil patch in Alberta in the 1960's & 70's. At that time
directional drilling was expensive and uncertain. Straight drilling was done
by using very heavy "drill collars" at the bottom of the drill string. The
bits were usually three steel cones with carbide buttons on them.The cones
were mounted on bearings with the base of the cones just off the centre line
of the drill and the point of the cone facing outward. Drilling mud was
pumped down the centre of the drill string,and the entire string was
rotated. The buttons on the bit broke up the rock and the chips were flushed
up the annulus between the hole and the drill string. This mud was allowed
to run over a "shale shaker" which separated any large chips. The mud was
recirculated continuously. After a while the bit wear and drilling would
slow. This meant that the entire drill string had to be pulled out,
unscrewed into 90 ft sections and stacked on end in derrick. In those days
the deepest holes in Alberta were about 17,00 ft. It could take over 24
hours of heavy ,dirty work to replace a bit so bit quality was paramount.
Directional drilling has matured enormously since then so I'm not familiar
with present procedures


I also worked on rigs in Alberta in the 70's . Did lots of deep hole
directional drilling . Certainly in those days it was anything but
hi-tech . Three kinds of bits . Diamond used only when pulling core
samples . Toothed bits when the substrata was soft rock and button bits
when the rock was harder . When passing through strata the wrong style
bit pretty much stops progress so you have to pull the entire pipe out
and switch them . I never got as deep as 17,000 but 13,000 took about 17
hours round trip . Dangerous time . Every time the pipe is pulled a long
metal rod is dropped down the center of the drill stem . Inside is a
small compass and a point the punctures it to show the compass heading
at the bottom of the hole . If drilling is going smoothly and the pipe
is not pulled often the rod/compass is dropped down connected to a sand
line after it hits bottom it is winched back up before drilling can
proceed . If the bit has wandered to the right heading heavy thick pipes
(collars) are added right behind the bit to hold it at the desired
course . these do not flex so bore straight . In addition every so often
a specialty outfit is brought in with a contained compass and a camera .

One of the guys I work with used to do directional drilling for the
construction company. I'm under the impression that they can drill a hole 4
to ? what ever deep and many yards long and make it come out a hole
somewhere down the line.
He had said that you can drill under just about anything, make it go up and
down and around stuff when needed. Of course he also said that they have hit
telephone, gas, water, and power lines doing this drilling.

Hell ! Around Brooks and Medicine Hat they moved every second day. Most of
the time they started drilling ahead half an hour after theyfinished
cementing the surface casing. Eventually they started going a week a head
with a small rig that drilled and set casing on the surface hole. At least
then, when the damned hole blew out on them, the surface casing was well
cemented in and the BOP stopped the drill string from ending up in
Saskatchewan.

Where the big deep hole ones sat in one spot for 6
to 8 months .



South of Calgary was bad hole counrty, and they used to take 6 or seven
months to do a 12,000 ft hole. If they put any weight on the string it would
take off down the first weak spot in the formation and you'd have no idea
where it would end up. The rig crews loved it because the bits lasted for
ever with no weight on them and they'd only trip the hole about once a week.

Oilwells are drilled with predetermined goals in mind. The
target strata is not always right under the oil rig. Hence,
they use "directional drilling" to make the bit go in the
direction they want it to. That way, they can puncture
several levels of strata with one well to recover as much oil
as they can.

Directional drilling is achieved in many ways. It is far to
complicated to explain here in a few paragraphs. Google it
and read away. Basically, it is just a way to change the
direction of a bit to hit a known reserve. Modern advances
allow drillers to make sharper turns. A drillstem is made of
steel, but anything thousands of feet long has flex in it.


I imagine that has led to some pretty heated discussions (and
beyond) when someone's drill hole ends up under the next door
neighbor's property.

Or, am I wrong in assuming that one's oil and mineral rights
extend down to the center of the earth?

And what about draining the oil out of a strata which extends
under someone else's property - through a drill hole that's
totally under yours?

The lawyers must eat up this kind of stuff. G

I think the idea of real time would be a huge hit . Only one snag .
Getting the Gov to accept the results . No doubt they would after
dragging the inventor through endless expensive tests . I great idea
that should be in use now . The trick should be how to avoid abrasion on
the wire from the high pressure mud going down the pipe . Not sure about
now but I seem to remember at the pump the pressure was 1800PSI , add to
that half a lb. or so for every foot of depth . Gets real high on deep
holes . If you use the stem itself how do you maintain contact when each
joint is doped ? No doubt there are solutions but not easy ones .

ever with no weight on them and they'd only trip the hole about once a week.


Worked northwest of Calgary right in the mountains myself . The problem
was the folded strata . We would get 2 or 3 lengths and hit soft or hard
and need a different style bit . I remember one stretch , we tripped
every day for 48 straight . Was a bad time , leave camp and get to the
rig to see half a dozen lengths racked . Knew we had a long muddy shift
ahead . The real rub was the chart would show no drill progress for
three hours . So those guys sat and waited till the end of their shift
so the next two shifts would have to do it all . Caused several fist
fights in fact . I never once saw a BOP valve used .

I worked in the oil patch in Alberta in the 1960's & 70's. At that time
directional drilling was expensive and uncertain. Straight drilling
was done
by using very heavy "drill collars" at the bottom of the drill
string. The
bits were usually three steel cones with carbide buttons on them.The
cones
were mounted on bearings with the base of the cones just off the
centre line
of the drill and the point of the cone facing outward. Drilling mud was
pumped down the centre of the drill string,and the entire string was
rotated. The buttons on the bit broke up the rock and the chips were
flushed
up the annulus between the hole and the drill string. This mud was
allowed
to run over a "shale shaker" which separated any large chips. The mud
was
recirculated continuously. After a while the bit wear and drilling would
slow. This meant that the entire drill string had to be pulled out,
unscrewed into 90 ft sections and stacked on end in derrick. In those
days
the deepest holes in Alberta were about 17,00 ft. It could take over 24
hours of heavy ,dirty work to replace a bit so bit quality was
paramount.
Directional drilling has matured enormously since then so I'm not
familiar
with present procedures


I also worked on rigs in Alberta in the 70's . Did lots of deep hole
directional drilling . Certainly in those days it was anything but
hi-tech . Three kinds of bits . Diamond used only when pulling core
samples . Toothed bits when the substrata was soft rock and button
bits when the rock was harder . When passing through strata the wrong
style bit pretty much stops progress so you have to pull the entire
pipe out and switch them . I never got as deep as 17,000 but 13,000
took about 17 hours round trip . Dangerous time . Every time the pipe
is pulled a long metal rod is dropped down the center of the drill
stem . Inside is a small compass and a point the punctures it to show
the compass heading at the bottom of the hole . If drilling is going
smoothly and the pipe is not pulled often the rod/compass is dropped
down connected to a sand line after it hits bottom it is winched back
up before drilling can proceed . If the bit has wandered to the right
heading heavy thick pipes (collars) are added right behind the bit to
hold it at the desired course . these do not flex so bore straight .
In addition every so often a specialty outfit is brought in with a
contained compass and a camera . Pictures are taken showing the
heading at carefully monitored distances . In addition every piece of
drill stem in measured before it is added to the string . With the
compass shots and the exact lengths they know very accurately where
the bit is at any given depth . It is also sent to the Gov . I know
there was lots of talk in the real old days about slant drilling but
by the time I got on a rig it was pretty much over , at least in the
corner of the world I worked . I had friends that worked in Indonesia
and China , same there they told me . I never saw a gun or heard of
anyone shooting at anyone either . All I worked were exploratory holes
so what was found was of great interest to the competition and yes
there were spies to watch and film . That said if oil was found
everyone told everyone they knew . I doubt there was any need to shoot
at anyone to protect what would be common knowledge . Hey maybe not
ideal but try stop a batch of 20 year old kids when they know
something ;-) . 90 foot sections of pipe flex at least 10 feet when
racking them . So you worked on a triple , me too . There were at
least four quads in Alberta working when I was there so 120 pulls . In
the south hundreds of singles 30 foot pulls and doubles 60 foot pulls
. I never worked any small rigs but guys told me they would go on long
change and have to phone the office to find the new location . Those
rigs moved weekly . Where the big deep hole ones sat in one spot for 6
to 8 months .

Nice note Ken -

I knew a fellow scientist at SLB (another lifetime and a better brain I
tell you!)
he was working on and broke it - how to data log with tools in real time
while
drilling ! - Normally a bit is extracted and then the tool set is
dropped down-hole.
This took time and time is money! - Besides - think of having an
expensive crew there
during a extract and drop and pull - or while you drill - the convince
won. Money
was not considered - just tell me today if I have half a change of oil
or if
that pinch out sand group was ever touched... Real time is great for
joy stick control
(almost :-) ) I know how he got by the signal - one "wire" is the drill
stem/pipe system...

I think the idea of real time would be a huge hit . Only one snag .
Getting the Gov to accept the results . No doubt they would after
dragging the inventor through endless expensive tests . I great idea
that should be in use now . The trick should be how to avoid abrasion on
the wire from the high pressure mud going down the pipe . Not sure about
now but I seem to remember at the pump the pressure was 1800PSI , add to
that half a lb. or so for every foot of depth . Gets real high on deep
holes . If you use the stem itself how do you maintain contact when each
joint is doped ? No doubt there are solutions but not easy ones .

I saw a drunken tool pusher kill himself one night by hammering on a
hammer union in the flow line to stop a leak. Im not sure what killed
him..the flying pieces of union and pipe or the initial jet of ultra
high pressure drilling mud. I do know I scrounged up quite a number of
disconnected pieces of him.

Don't get it right there Ken - there isn't a wire.
The 'wire' is the drill stem and pipe to the surface.
The other wire was the tough one - oh just use Earth - e.g. ground it.

On the top naturally there is a connection - a sliding brush.

The Gov doesn't have to accept squat. - The customer base does.

For a patent - piece of cake. There are sites and wells that are logged
as standards all the time. In fact, test wells are drilled on site at the
research site. Just log well xyz and drill one next to xyz and compare results.
But for patents you don't need this stuff - just the setup that is unique...

Naturally this logging isn't all forms of logging - some of those are really exotic.

I did think the pipe might be a source but every joint is doped and a
reliable connection will be tricky . Holes drilled under Gov leases have
to meet Gov specs . Not that the accuracy would not be there but getting
a Gov to see it , well you know . Luck though it is a good idea
