Your situation is the same as mine. I went there in 2009 and went back to graduate school on 10. Don't worry about the penalty. The oil field is not bad. I only need to pay the training fee (I paid the training fee of 5,000 yuan at that time, but I have to subtract 1000 for one year's work, and you may have to subtract 2,000 yuan) and return the settling-in fee of 5,000 yuan. Then do a good job of the household registration book yourself, then go to the organization department on the sixth floor of the office building to ask for the address of the archives room, and then write a letter to the school, and they will mail it to you. This is even, just study hard. Come on!
