Reservoir pressure and temperature measurements have become the cornerstone of reservoir and production management. These measurements provide improved capabilities for understanding of oil and gas reservoir characteristics, which enables greater reservoir management for increased production and improved ultimate recovery.

The reliability and accuracy of permanent downhole pressure and temperature technologies is therefore of the highest priority when planning field developments, be it green fields, brown fields, marginal fields or EOR projects. The long term Permanent downhole gauge and Fiber Optic contract was awarded in August 2010 with the intent to provide reservoir monitoring with the highest reliability and accuracy that was available. Since the award of the contract, the world-class milestone of 50 installations was achieved in August 2013. This milestone has been enhanced by the fact that to date, an amazing success rate of 100% has been realized.

This success story has been achieved by a combination of many factors, from the strong validation process for gauge selection and subsequent choice of world class technologies with the highest survivability in the oil industry, close collaboration between the project and operations teams of the oil company and service provider, project management expertise, detailed preparation and maintenance, to the philosophy of providing real time data delivery to the end user.

This paper highlights the technologies installed and processes charted over the last three years to achieve this remarkable success story.
