Aker Oilfield Services Short Introduction

There is a need for solutions and capacity for cost efficient subsea well services

40%

25%

Gap in recovery from subsea fields

Releasing lost / trapped production subsea is by far the most cost effective production increase (IOR) initiative;

• No infrastructure investment required • Fully integrated solutions provides limited resource requirements
