I just joined Schlumberger as a Junior Drilling Engineer/ Drilling Engineer trainee.

For the first 2 yrs, I'll be assigned to work in a field as:
- MWD/LWD Field Engineer for one an a half year
- DD-Trainee/ Second hand Directional Driller for 1/2 -1 yrs

After 2 yrs, I'll be assigned as a drilling engineer.

Since this is a new career path of SLB, could you please share the advantages/disadvantages of this postion compare to Oil company drilling engineer?

and,

After 4-6 yrs experiences, Is it a good idea to join oil company?
