Transocean Vs Schlumberger, Kca Deutag Vs Halliburton

I am gettin confused here about which of them do drilling
This is what i think..
Transocean spud d well but when its getting to the reservoir, schlum B take over and run wireline and loggin tools
making schlumB a half drilling company, mayb that is why schlum B dont own any rig
Same goes to deutag and halliburton...Deutag is a complete drilling company while halliburton come in when there is need for directional drilling and MWD/LWD operation
This bring me to ask this question???
Is transocean too small to acquire Directional drilling/LWD/MWD technology???

No need to confuse yourself. Transocean and Deutag are DRILLING CONTRACTORS. They own rigs and do the drilling. Halliburton and Schlumberger are Oilfield service companies. They do not own rigs. They simply supply products that help the operator(with the aid of the drilling contractor) get to the pay-zone. Halliburton and Schlum provide things such as directional drilling tools and services for horizontal/s shaped wells, completion tools like frac tools, wireline services for gyros/surveys etc.

@9jah. U ar right.

@Xyoung: 9JAH has said it all, however companies like Schlum, Halliburton and Baker Hughes because of their "meganess" go as far as providing a wide range of services thru subsidiary companies they own. So as such, they might actually peroform much of drilling sercives (eg Schlum owns ANADRILL). But KCA Deutag and Tranocean fall purely into the class of Drilling contractors (i.e they drill and own and lease out rigs)

@all....thanks but i am still confused
Why cant Transocean and Kca deutag perform all drilling operations from start to finish.
Does transocean own directional drilling tools?

Where does Saipem come into play?

As far as i know, transocean does not own directional drilling tools. They own rigs. Hal, schlum, baker hughes and other small service companies own directional drilling tools. When they say directional drilling tools, they do not mean any component of a drilling rig. Directional tools are just part of the BHA(bottom hole assembly) and they include drill bits(pdc, tricyclone etc), mud motor (this enables horizontal wells to be drilled), mwd tools etc.
Transocean, like other drilling contractors, performs the actual drilling because they OWN the drilling rigs. They also staff d rigs.. The operator (exxon, shell, chevron etc) only tells them where and when they want to drill. THe service companies like schlum, baker and halliburton on the other hand have tools that are proprietary. This tools such as mud motors (with bends) are attached to the drilling contractors bottom hole assembly (BHA) in order to aid drilling. In essence, the service guys are there to "enhance" drilling. Same thing applies to the completions aspect.
As small as the drilling to completions process looks, it can also get complex pretty quick. This is why companies have chosen to specialize. With regards to whether or not the drilling contractors can actually do everything, Yeah they sure can but at the end of the day, will it be cost effective? I believe there is even an operator that actually owns a drilling rig and performs some of its own directional drilling jobs...(c

At the end of the day, it is cost effective for you to just pay someone that specializes in a certain aspect because that is what they do and they've probably done extensive R&D in that field.

Saipem is an operator. They own the "cheddar"...lol..

^^^^^^^Actually i take that back. Eni is the operator. I think they own Saipem

I have a question, what about a service company that wants to own a rig? Where do u place them. @9jah. Your second explanation is head- blowing. So many things were involved. I know a service company that has its set of bottom hole assembly. They lease out tools to operators for drilling.

For clarification, a drilling rig comprises the derrick, rig floor, top drive/kelly and does not include directional drilling tools. You can google drilling pictures for better understanding and definitions.
Actually, all service companies own/should own some sort of BHA. Don't confuse BHA with the drilling rig. The BHA is just the last part of the tool string to which drill pipe is attached. For clarification, starting from the bottom of the hole, you have your Drill bit (that rotates and cuts into the earth/formation), then your BHA (this BHA will include mudmotors and MWD tools - employed for directional drilling), and then drill pipe and whatever is needed.
With regards to a service company owning a rig....They technically can but the question is why? You don't just own a rig so that you can drill one well or two. You own rigs so that companies/operators can contract them out and use them to drill. If you own a rig and you are an oil service contractor, would you be willing to allow your competition utilize their directional tools on your rig......knowing you also have directional tools?
It makes life easier and makes for better competition to just separate Oil Operators from Drilling Contractors and Oil service guys.

i luv dis thread. Rily informative, explicit and mind blowing. Thanks 4 ur contributions my ril guys. Keep on d guy work

@9jah, lovely piece...

@all, the oil industry is where 'division of labour is explicitely practised' and everyone in each segment gives her best to outdo her competitors.

The comments in this thread so far are highly commendable and that is what it should be for other threads too-Cascading information and insightful too; not otherwise. Good work guys. See you all on top!

BHA normally comprises of all the string ran in hole below the drill pipe while drilling and they could be made up of a drill bit, bit sub, near bit or string stabilizer(for directional control, gauging the hole size and help to stabilize string), float sub(contains flapper that ensures one way flow and useful for well control), drill collar(providing weight on bit), mud motor(using rotor-stator arrangement for directional control), rotary steerable motor(using activation pads for directional control), MWD tools (for inclination and depth(MD, TVD) measurement), LWD tool(contains radio active material and used for measuring the resistivity, density, neutron porosity, sonic etc) mainly for lithology and fluid content measurement, Gyro(used for depth and inclination measurement when magnetic interference is expected as conventional MWD give erroneous measurement when there is magnetic interference), hole opener assembly.e.t.c.

Keep it up guys.I love dis

In addition to what 9jah says, SAIPEM also own a drilling company, though i don't know the name of the subsidiary that drills anyway but am sure they also drill offshore. Their SCARABEO-3 just ended their drilling campaign in one of Nigeria's offshore fields

what does case hole completion mean abeg

I have been opportune to work in kca deutag T-209 rig and SchlumB drilling and measurement dept...Dat was wat aroused my questionin...knw of a BHA tools owned by schlumB..check out Tecon..de own oil well and drill also..Companies are becoming versatile..when I checked out d list of top drilling companies in d world, I came across Fugro, which also acquire geological data and shoot seismic..My guess is dat one day, Transocean will acquire SchlumB...LOL
Remember schlumB bought over smith, pathfinder, geoservice and baroid which were specialized companies

Just pray let God direct you...ur future is in his hand no body knows wat best suits you..he makes away were is seems no way..it dose not matter d position, money or company ur starting withz, wat matters is what God says abt you..and nufing much..all human aadvice aand suggestions are based on their personal experiance, ur case couud be defrent..wshn u nice carre ahead. Cheers

@engr...very simple..resign from d police and join nnpc..sure u dnt wanna build a career wit d NPF

@all

I want to ask a question, can working for a drilling contractor over a period of time get u a job with an operator.

Which is d prefered place to work? A drilling contractor or a.n oil servicing company?
