Nigeria is Africa's biggest crude producer but its revenue is severely reduced by theft and attacks on oil pipelines that significantly impacts crude production and fuel supply. Substantial efforts have taken place in collaboration with local communities, producers and oil operators to engage New Technologies in a bid to combat oil theft and pipeline sabotage. Integrity monitoring of oil and gas pipeline pipelines can quickly identify a leak or third-party incursion event. Distributed optical fibre sensing offers a pipeline monitoring system that is not available with any other technology. Early detection of a leak or intrusion together with the accurate identification of the location allows time for either safe shutdown or rapid dispatch of security, assessment and clean-up personnel giving benefits in terms of reduced environmental impact and reduced helth risks to the local population. An effective and appropriately implemented monitoring system can easily pay for itself through reduced product loss, potential consequential losses and an increase in public confidence. A Distributed surveillance system one of the first installed in Nigeria will be introduced. The System has been introduced to the Umugini pipeline, a crude oil evacuation route for four Nigerian marginal field producers in the western Niger Delta. The system uses the FALCON Platform developed by Xenergi. The system includes intrusion detection and leak detection based on both acoustic and temperature variations. At the heart of the system are both the Ultima™ Distributed Temperature Sensor (DTS) and Distributed Acoustic Sensor (intelligent DAS) allowing coverage of ranges up to 10's km continuously. The project had to overcome a number of challenges, including the variable installation conditions imposed by the terrain & local climate, contractors unfamiliar with the technology and community concerns. Overcoming these issues gave a system that delivers 24/7 coverage of the Umigini pipeline from a single monitoring location giving the operator financial benefits in reduced product loss and more efficient deployment of resources. The Silixa intelligent Pipeline Surveillance System (iPSS™) allows oil & gas pipeline operators to continuously and simultaneously monitor for leaks and threats to the pipeline along its entire length, and is the only system that can offer such complete coverage. Utilising fibre optics and underpinning the detection technology is Silixa's world leading Ultima & intelligent DAS, (iDAS™). The iPSS brings together this advanced technology, applies sophisticated processing and presents vital information through an easy to use interface.
