What is the Information Technology landscape like in the petroleum industry? Are there a few major software vendors? a lot of in house home grown IT projects? a mix of both?
I’d be interested in knowing myself.
My side of it is the engineering/design of the facilities. Much of the software we use is not specific to the oil/gas industry. I don't know enough to answer your question.

I’m on the field engineering side. The only proprietary software I’m aware of is in the seismic arena where the logging, mapping, etc. of the formations are done. They keep those cards pretty close to their chest. Everything else out here in the field is the same commercial software that most any other company would use depending on the specific need. Some of these remote locations present major logistic problems with internet access along with phone service. Not sure that answers your question.
There are both, but if I was looking for an IT job, I’d check with individual oil companies, service companies (Schlumberger, for instance, and MWD companies), and companies who write software like Petra.
