Dear Sir/Madam,
As you can see, I have had extensive experience not just in the Oil & Gas sector having worked across multiple sectors, giving me varied skills and the ability to work with many different types of people. I believe I could fit easily into your team.
I am a conscientious person who works hard and pays attention to detail. I have good interpersonal skills so work extremely well as part of a team but also when left to my own devices. I'm flexible, quick to pick up new skills and motivated to continue learning. I have lots of ideas which I am always willing to share and enthusiasm. I have excellent references and would be delighted to discuss the vacancy with you at your convenience.
Yours Faithfully
Richard Bowie
