What we do

one&zero provide experienced wireline witness and consultancy services to the upstream oil and gas industry

Our services are based on what we call OPERA: Operational Planning, Preparation, Execution, Review and Analysis.

The system takes our experiences of wireline operations and puts that into a remote witness portal for delivering the highest quality job performance at the wellsite.
