HVAC to reservoir engineering

Hi Guys,
I am so happy that I found this forum only by chance.

I graduated in Mecheng at 2003, I was working as mechanical Estimator for 5 years and also at the same time I was involved in HVAC design engineering as well for only 2 years.Since about 2 years ago till now t I have been working as Site Supervisor in building Mechanical Services field (HVAC) in Australia Sydney.

Since many years ago I was interested in reservoir engineering but I didn't know how to shift to that field. I have NO idea about it to be honest . generally I know , that would be a blend of fluid mechanic, geology and thermodynamic . I was perfect in thermodynamic and fluid mechanics during university years but we never studied Geology .
Now I am thinking to take a course to get a Master degree in Reservoir Engineering. In Australia, UNSW is offering a Postgraduate program in Petroleum Engineering but you need 1 year experience in industry and I don't have it. Also I couldn't find any thing specifically designed as reservoir eng program for Master degree here in AUS universities
I talked to one of my friends who has been working in this field for a long time and he suggested me to find a job first. He told me some companies such as Schlumberger or Haliburton may give me a position -Although I don't think so- then after 1 year experience I can apply for Master degree.
I only want to work in Australia and also I would like to know about life style of a reservoir engineer , how long I would be away from my family and ....
I really appreciate it if you would advise me what is your idea about my dream.I want to make it clear for myself that is it possible to find a job in this field without experience or not . and Also I need to analyse my character to see if I can accept this new life style.In fact I want to make a realistic decision. When you google this subject you can find a lot of clips on youtube showing a happy life for drillers, field engineers and .... but how much it is true.I don't know

Thanks for your help

Res Eng typically works primarily in the office. Occaisional site visits only.
Suggest you find a university that will allow you to do a 1 year Masters in Petroleum Engineering with the experience you have to date, and select Res Eng topics. Try Australian School of Petroleum (ASP) in Adelaide. Dont bother with Halco or SLB, they wont teach you how to be Res Eng with your background
