I am very interested to become a drilling engineer. After reading Version 1 to Version 8 of this thread, I am unable to consolidate the enormous information about drilling engineer, hence the following are my questions.
1) Are the differences (especially in term of job scope) between drilling engineers in oilfield service company, drilling contractor and operating company very significant?
2) Are skills learned in one type of company relevant in other two types of companies? For example, can a drilling engineer from Drilling Contractor work in a Oilfield Service Company?
3) In drilling contractor, is a driller same as a drilling engineer?
Thanks for the your advices which are very much appreciated.Â

as far as i know;
1. DE (operator) - write the noop (well program) mainly based on the information from the subsurface, as well as discussion with drilling/completion team. Gathering the info they get from the oilfield services into the well program. They have the requirements and oilfield services will propose to operator which tools that meet that requirements. Be a onshore focal point when drilling is executed. some operators have drilling superintendent that will lead the drilling team but some they only have head of drilling that comes from the DE itself. Drilling supervisor/companyman on the rig reports to drilling supt or head of drilling. Basically DE needs to have all rounder knowledge (i.e mud, bit, dd, etc.)
DE in oilfield companies if i'm not mistaken provide or propose the tools or technology that meet the operator requirement to drill the well. they also run simulations with the tools with a certain parameters and info the provided by the operator.
2. Some of the DE in operators came from services company and previously a field engineer such as mud engineer or MWD. Most of the DE come from fresh grad and gains experience from there. Drilling Contractors DONT HAVE a Drilling Engineer.
3. Drillers are NOT Drilling Engineer. Driller drills the hole as per well program or SI (standing instruction) written by the companyman. When drills directional hole, driller will follow directional driller's instruction, when performing operations with specific tools, the tool specialist (i.e fishing supervisor, linerhands etc) will advise and instruct driller what to do to work with their tools.
You dont have to have a degree to become a driller. but being a driller, you are responsible of the safety on the rig floor and your duty to shut in the well if you think it is necessary.
Normally driller comes from people who worked hard from bottom (roustabout, roughneck, derrick/pumpman, assist driller and driller) or there is also now a driller trainee program (fast track program).
