TERA's project experience in pipeline transportation covers network modeling and optimization for natural gas, crude oil, and petroleum product pipelines. TERA supported the U.S. Department of Energy's Project Independence Evaluation System (PIES) and Midrange Energy Forecasting System (MEFS) analyses by providing the national pipeline network algorithms and evaluating additional capacity needs to mitigate anticipated bottlenecks.

TERA's regional and national pipeline network models such as GASNET, TERASIM and FNEM have been used by various federal agencies to analyze a wide variety of issues ranging from strategic petroleum reserve storage locations and disposition of Alaska North Slope oil to well head pricing of crude oil and natural gas, and location of deepwater ports and refineries.

Comprehensive data validation studies conducted by TERA documented the U.S. industry practices in collecting, manipulating and reporting oil and gas data by the energy industry to the Federal Government in numerous periodic reports. TERA's work supported the report jointly submitted by the Secretaries of Transportation and Energy to the President on national energy transportation needs and two annual reports to the U.S. Congress by the Energy Information Administrator on capital requirements for natural gas and oil product movements through the national pipeline networks.

TERA also conducted an evaluation of the Trans-Balkan oil pipeline project between Burgas, Bulgaria and Vlora, Albania and assisted in the study of alternative routing of Caspian crude oil to international markets. As part of the Intermodal Transport Capacity Manual published by the U.S. National Academy of Sciences, Transportation Research Board, TERA prepared the chapter on estimating pipeline throughput capacity for various liquids based on chemical and physical parameters.
