Logo to re-brand successful technical oil industry company

Rushmore Reviews

Please see http://www.RushmoreReviews.com.

We provide a service for oil companies to share data between themselves relating to the drilling of their wells. Established 1993 our website / branding etc is now very out of date.

I was intending to start with a website design contest but decided, having seen some great work on logo's on 99designs that we should probably get the logo designed first.

You will see our current "branding" at the top of the website. It includes a magnifying glass (looking at data), a globe (as we are global) and an oil rig (of course).

We are now looking for much cleaner website and this banner style / shape does not really work for that so I'm looking for a more usual type / shape logo to be used on website / brochures / display stands / business cards / advertisements.

Its 'business to business' and aimed at drilling / exploration / technical managers in oil companies. They will be mainly male, middle aged and of an engineer'y tendency.

Please include the words 'Rushmore Reviews' and the tagline 'offset well data'.

Please do not use 'oil drop' image.

An image that shows 'drilling down into the data' may work?

We need to stay with a predominantly blue colour (as per website) as our site / literature / business cards have been blue since the beginning and I suspect a total colour change would not work too well.

Logo needs to be hard / technical-ish and ideally relate in some way to data / global / drilling although I am open to creative alternatives

Like logo on white background please.

Ignore the "Rushmore Associates" and "Sigma" logos on the website banner - I want a new one for "Rushmore Reviews" that ideally relates in some way to data and/or drilling and/or global.
