Conclusions
WIEN says the benchmarking so far has meant operators have gained a collective and overall improvement in oil and gas recovery from their wells through sharing what works.
The credibility of the data will increase as more data is benchmarked on an annual basis to identify further technology needs, inform well intervention strategies and support further collaboration projects.
Further to the 2010 benchmarking data, WIEN has received data relating to an additional 1167 and 1288 well interventions executed in 2011 and 2012,

Powerful jumper and umbilical monitoring
As subsea field umbilical arrays grow ever more complex then the integrity of the components becomes increasingly critical.
C-Kore is designed to provide assurance to field installation engineers that their umbilical systems will meet the client requirements by checking electrical integrity immediately prior to connector make-up.
