Task 1. Read an e-mail written by a consultant petroleum geologist, Paul Selby, to the manager of the Exploration Division of a large oil and gas company in Qatar, Adel Al-Jalawi. What is the purpose of the e-mail?

Задание 1. Прочитайте электронное письмо геолога-консультанта Пола Селби руководителю отдела разведки месторождений одной из больших нефтегазовых компаний в Катаре Адель-аль-Жалави. Какова цель писма?


Dear Mr Al-Jalawi

I contacted you just over two years ago and you were good enough to allow me time to show you some data we had assembled on prospects in the Ngosso and Iroko license areas off the coast of Cameroon. In the end, you decided not to invest in this area, but as you will know, it has become apparent since then that there are some excellent prospects here. A number of other companies have drilled wildcats and over a dozen wells are now producing. We have continued to do research offshore of Cameroon, as well as of Gabon and Equitorial Guinea, and we have now teamed up with a seismic company, Exploration Geosciences. If you would be interested in seeing our findings on more than 20 prospects in offshore West Africa, I would be delighted to make an appointment to present and discuss them in greater depth. I have attached an updated list of our main petroleum geology services. I look forward to hearing from you.

Yours sincerely,

Paul Selby

Managing Director, Selby Geo-Prospects Ltd
