Oil Comp Engr
38 Years Experience
Houston, TX
Female, 60
I recently retired from a major integrated oil company after 38 years. I have degrees in Civil and Petroleum Engineering. I worked with safety, health and environmental management systems and operations in the upstream (finding and producing oil and gas) and downstream (refining, chemicals and distributions) areas. I travelled all over world, enduring good & bad business cycles and good and bad managers.
It will depend on the particular university you plan to attend. However many of your undergraduate classes like physics, statics, dynamics, calculus will be similar to what the petroleum undergraduates will have had. One thing they will have had that you will need is some geology courses. You should be able to catch up pretty quick, though.
Unless you are at the VERY top of your class when you graduate, you may have a hard time finding a job. In the US, we have shed nearly 150,000 jobs over the last 6 months due to the severe drop in the price of oil. Petroleum engineering graduates in the US are having a very difficult time finding a job. I would strongly recommend that you broaden your background by getting a degree in mechanical or civil engineering. Civil is a good fit with your geological background (I have my bachelor's in Civil). In this way you may be able to get a job outside the oil industry. It may pay less than petroleum engineers are making but you have a better chance of getting at least some kind of job. When the price of oil recovers (it will, but it's just a matter of time and it may take years), you can always jump back into the oil industry.
If you are still in school, the number one thing you could do would be to land an internship working for an oil and gas company. That will give you some practical experience. You could also take some courses in Petroleum engineering and geology. The basic problem solving skills you have learned as a chemical engineer will serve you well as a petroleum engineer. Based on the current market conditions, however, the competition is very intense for petroleum engineering jobs. You need to have great grades, good leadership experience (president of a technical society, a sorority or fraternity), good people skills and solid recommendations from professors.
Please check out earlier posts. I've already addressed that question.

That's a somewhat subjective question, but if you want to measure it on a basis of the total carbon footprint, then clearly oil sands production creates the largest carbon footprint. To extract oil from oil sands requires a very large amount of energy to separate the petroleum from the reservoir rock. That energy is typically generated by burning fossil fuel (either oil or natural gas). The ratio of energy obtained for every unit of energy input is referred to as the Energy Returned on Investment (EROI). For conventional oil production, the ratio is about 25 to 1. For oil sands mining, it is about 5 to 1. This is why oil sands mining is only economical when the price of oil is relatively high. So, from the standpoint of carbon footprint, I would consider it the worst. In terms of net impact to the environment, with proper regulation and oversight, industry can and has been able to responsibly extract petroleum and return the environment to a suitable state in a relatively reasonable period of time. So, I can't really rate all other methods as to which is "best". It is highly dependent on local conditions, local regulations and the integrity and internal standards of the company doing the work.
Wow, if I could tell you what is going to happen in the short term, I'd quit my job and spend my days trading oil and gas stocks. Over the long term, you can bet that whatever is happening now is going to change. I would suggest you read some of the great books written on the history of the oil business, like Daniel Yergin's "The Prize". The oil and gas business has always been very cyclical and probably always will be. So long as there are a diversity of countries with oil and gas assets operating under a diversity of political regimes, it's going to be an unpredictable situation.
I certainly don't use ALL of the math I learned every day when I do Petroleum engineering work, however, I can say that all the math I learned serves as the foundation for many of the software programs and simulations in reservoir modeling and drilling engineering design work that I have done. In order to trust the software that you use, you do need to understand what goes on behind the scenes. I will have to say that one of my favorite classes in college was Systems Science and Mathematics. The course was composed entirely of real world problems and the various mathematical methods used to solve each kind of problem.
