Spectra Energy announced that it has the support of Horn River producers for an expansion of Spectra's pipeline system serving the Horn River shale gas region of northeastern British Columbia. Seven producers in the region near Fort Nelson have committed to ship 760 mcf of gas per day on a revamped gathering and processing system. Work on the system is expecting to begin later this year, concluding in 2012. The project would include bringing Spectra's Fort Nelson gas-processing plant back to full capacity, adding capacity to its current system and boosting the size of compressors. Companies operating in the Horn River region have reported finding trillions of cubic feet of gas under their properties, ranking the discoveries among Canada's largest. Other pipeline companies have also announced projects in the region. TransCanada announced last month that Horn River producers backed its plans for a new $340 million pipeline to ship natural gas from the region to market.
