The oil and gas industry's tighter margins have opened up space for innovation in drilling. Upstream Technology's Spotlight on Drilling highlights some of the ways drillers are using technology to pare costs and boost efficiency.

Controls mission

A Norwegian company is aiming to make drilling operations safer and more cost-effective with new technology, including an all-electric blowout control system.

Moveable feats

A new production concept centred on dry tree completions aims to cut drilling and development costs in the high-pressure Paleogene.

The brains behind the bit

A self-adjusting drillbit began as a clever concept in a company-wide innovation contest. Now its backers say the adaptive “smart” bit could become an industry standard.
