I have a bachelor as a mechanical engineer. In order for me to have gotten hired, i think it was necessary. Not because you need all the knowledge, but it gives you an edge over the hundreds of applications for positions like this in Norway.
Yes, stay in there. But i wouldn't focus exclusive on MWD, there might be good opportunities in MUD, LWD and MPD also. Check it out.
I played the CV-database game for quite some time. It's actually been 7 months since i graduated(traveled SEA while applying onine, doing skype interviews). And I was almost certain it was impossible. But I actually did get some response from them all in the end.
If they allow you to upload a custom CV, make sure it looks really clean, maybe some color to lighten it up a little. If you receive hundreds of CV, a messy one will easily be disposed. And do the normal follow up call, bring some question if you can think of them.
I also read this book about doing interview. I honestly think it saved me in my last interview.

After 25 minutes they were already like "Okay then, so we met and had a small chat. NIce to meet you. We'll talk together and give you a call next week. A phone interview will probably do" I really did not get a good feeling from this ending.
Then i had the balls to tell the manager of hundreds of people: "Oh, this went really fast. i would love to hear some more about the organization".I know how important his time is, so this was kind of a big deal to me, asking for more time, very unlike me. And after I kept controlling the interview asking questions at the same time telling good thinks about myself in a subtle way. I would never have the balls to prolong the interview unless i read about it in this book.
One more bold question I asked was: "Is there anything about my background that gives you any doubt about hiring me?"
Then they gave a few points, which I managed to give good answers to. I think its important to really ask this questions, if people don't know, they think the worst.
Then follow up with a thank you letter after the meeting.
I also found out there are private mud schools around the world. This might be a good way if you are aiming to get a job within the smaller contractors.
