Application Oil field development

solution

Roxar METTE™

SOLUTION

Gas capped oil field with gas lift; 3 interconnected reservoirs:

First oil expected in 2016 , and expected lifetime of 20 years

What is the optimum development scenario?

Integrated approach mandatory due to tight schedule and

limited resources

Artificial lift and pressure boosting effect evaluation inluding

multiphase pumps with predicted gas lift and power needs

CHALLENGE

A comprehensive integrated flow assurance solution, including

production network optimization

RESULTS

Success Story - Integrated Production Management Oil Field – North Sea
