Q: What ’s the difference between Reservoirs Engineering and Reservoirs Simulation?
Only Petroleum Engineers!!!!!!
A: Gee, hope you don’t mind a humble chemist answering this, I mean we’d never reach the
Reservoir simulation is a tool used by reservoir engineers to understand and predict the behaviour of a reservoir, based on an almost certainly incomplete set of data. For this reason, reservoir simulation generally involves a ‘history matching’ approach, where the reservoir engineer builds a reservoir full field model (FFM) using simulation software, and then ‘fine tunes’ the model by adjusting some of the variables (rock permeability, connectivity between injection wells & producers, locations of faults, etc, etc) until the model predictions agree with historical behaviour. More art than science, really.
Reservoir engineering is the practice of managing the depletion of the reservoir, generally to maximise the production of hydrocarbons. Reservoir engineering therefore covers everything from the placement and orientation of wells (injectors and producers), determining the production rates from individual wells, the injection rates in injection wells, managing the pressure support, planning what injectors to switch on and when, whether to and when to employ EOR techniques……..
But what do I know, I’m only a chemist 
Q: What’s the best major in Petroleum Engineering.?
As I’m doing PE, there are three majors: Reservoir Studies, Drilling and Production Operations. so I would like to know from experienced people or engineers which of the three majors is the best one.
A: It really depends upon your own likes and dislikes. If you don’t like field work and would prefer sitting behind a computer doing simulation work then Reservoir would be the way to go. If you think you would like to be on drilling rigs for a the first part of your career then in the office more later advising other people on the rigs, then Drilling. If you like the field operations type work overseeing daily production of oil & gas then Production Operations.
There is a huge need for all 3 areas of study and non of those 3 stand out as the most desirable within the workforce.
Myself I chose to go the Production Engineering route long ago and have enjoyed it tremendously working both in the field at times and then in the office. However, I love field work and tolerate office work. I’ve become a Production Engineering adviser which takes me all over the world as a technical problem solver and also teaching technical workshops. I even decided a long time ago to go the technical career route instead of the management route as I enjoy the technical problems much more than people problems. However, you should try both as I did and pick for yourself.
Q: What do Reservoir Engineers do?
I’m seriously thinking about becoming a reservoir engineer when I graduate. I know that they’re the ones responsible for the production of a oil/gas field, though I would like to hear what they do first hand from someone who’s in the field and/or is doing petroleum engineering.
A: Reservoir Engineers verify reservoir performance through direct and indirect measurements of any given well’s or a multiplicity of wells’ performance.
Typically a Geologist will estimate oil and gas reserves of a given well or field to be 50 Billion Cubic Feet (BCF) of Natural Gas, based on the parameters available to the Geologist. The Reservoir Engineer typically comes on the scene once a Production Test has occured and informs the Geologist that he is delusional and that there is only 5 BCF based on the well’s production performance. They do this based on faster decline rates than anticipated, sudden or slow drops in reservoir pressure that signify insufficient Volume (P1V1/T1=P2V2/T2) to support 50 BCF. They can also tell by dderivativeequations of a reservoir whether a reservoir is performing to the model or not. There are Type Curves for a number of specific well performance types.
The Reservoir Engineer is rarely the Geologist’s best friend..lol. We often disagree but usually the engineer is right. If you are an geologist conversant with reservoir engineering however, you can scoop the engineer and prove him wrong however. If you can do this, then you can see others mistakes and exploit them for very big $$$$$$.
I had an engineer evaluate a well that tested about 30 Mcf/d and I thought well damage was an issue. He had the top experts look at the well and they said all it would make would be 90 Mcf/d. at best. The well made 4500 Mcf/d and discovered a pool worth $1.6 Billion. I got fired, the engineer stayed. I got nothing! He is a good friend of mine and reminds anyone who asks him who discovered the field…he always tells them to phone me.
Q: what is overpressured/abnormally reservoir, and what problems can it cause in drilling wells?
related to petroleum engineering mostly so i dont know wich section it corresponds to
A: This would be artesian conditions, when the pressure of the fluid is greater than the surrounding pressure because of a tight cap to the reservoir. This can push the fluid up, causing damage to the drilling equiptment. It can also cause what is known as a ‘gusher.’
Q: What is the current situations of employment for the freshers of the Petroleum field (mainly exploration)?
I am doing my masters in Petroleum Technology from Wadia college, Pune. I will complete the course in june 2010 and start the search for a job. I have heard that the situation was very bad till now but the good news is that it is picking up for betterment. I am looking for openings related to Logging, Drilling or Reservoir Engineering. The later one is more preferred. I had graduated in Geology and chose the petroleum field for post-graduation.Please let me know if there are any job openings or even any options similar to a post of a project assistant as I wish to learn more and more, but would not like to sit idle at home jobless. Any suggestions will be appreciated regarding this question.
A: Just check it out in your area of interest and the region where you are looking at ( it all depends how good you are and who do you know as a starter):

Q: Would a Japanese Petroleum Company accept foreign employees a.k.a Indian ?
Ok, its a big question and i couldn’t find any answers yet.. so i’m trying my luck here..! I’m doing my Undergraduation right now but i would like to gather more info on the field i’m interested in.. Reservoir Engineering.. I’m interested in japanese culture and it would be great to land a job in a Japanese Petroleum Company.. But so far i’ve no knowledge of the workings of a japanese company.. So i would be really grateful for anyone’s opinions or suggestion… ! .. thank you for your time.. ^-^
A: It is possible, for example Showa-shell says in their career Q&A page states they give equal opportunity for foreigners and foreign student. But it also means you have to compete with Japanese students so you have to speak Japanese fluently. And usually Japanese company hire foreigners through mid-career employment, not undergraduates. So I have to say it’s very difficult. Each company have its own policies of employment so perhaps you should ask those companies directly.
