Abstract: In light of volatile prices, the industry has assumed an every drop counts approach to running the business. In this environment, issues such unaccounted-for (UAF) gas, with which every operation has dealt before, nd themselves under new scrutiny. Production, gathering, midstream, pipeline and distribution companies are all responsible for managing UAF. Long gone are the days when the cost and impact of UAF was passed directly to the customer with virtually no requirements for managing and reducing costs associated with the loss. While UAF has, historically, been the result of a combination of issues, current trends in the industry have managed to further complicate it. Interest in shale plays has given rise to mergers and acquisitions, which have resulted in diversied, oil & gas operations. An increasing number of producers and midstream companies must track and balance multiple uids, including natural gas, natural gas liquids (NGLs) and heavier hydrocarbons in their systems. At the same time, measurement departments are faced with more ambitious UAF loss targets.
