Questar Energy Trading markets natural gas, oil and NGL. It combines gas volumes purchased from third parties and equity production (production from affiliates) to build a flexible and reliable portfolio. Questar Energy Trading pays Questar E&P index prices for production volumes. Questar Energy Trading then resells such volumes and bears profit-and-loss risk. As a wholesale-marketing entity, Questar Energy Trading concentrates on markets in the Pacific Northwest, Rocky Mountains and Midwest that are close to reserves owned by affiliates or accessible by major pipelines. It contracts for firm-transportation capacity on pipelines and firm-storage capacity at Clay Basin (a large baseload-storage facility owned by Questar Pipeline).
