Historic Throughput

Monthly Throughput

Shortly after the start of each month, Alyeska’s Oil Movements department compiles, confirms and releases the previous month’s TAPS throughput data, which is then promptly posted here.

Historic Throughput

TAPS throughput levels have had their ups and downs over nearly 44 years of operations. Less than three years after oil first entered the pipe on June 20, 1977, TAPS had already moved 1 billion barrels. In 2019, Alaska celebrated TAPS passing the 18 billion barrels milestone. Other highs: In 23 years, TAPS daily throughput averages were above 1 million barrels per day (bpd); throughput peaked in 1988, averaging an astonishing 2,032,928 bpd. The lows: In 2019, TAPS daily throughput landed below 500,000 barrels for the first time (490,366) and dipped further in 2020 (480,199).

Less oil in TAPS means slower-moving and colder oil, which creates complicated operational challenges. Alyeska and its owner companies continue analyzing the risks, options and challenges of declining throughput while creating mitigations and validating other potential steps through laboratory and field tests. Learn more about TAPS Flow Assurance challenges and solutions here.

The best long-term solution for TAPS operations is more oil. And there is optimism from increased activity on Alaska’s North Slope, as new technology and innovation helps operators discover new hot spots as well access more oil in old but reliable fields. Behind that momentum, TAPS throughput is predicted to climb in the years ahead, providing TAPS with #40More years of operations and fueling Alaska’s economy.

Totals are listed in barrels; one barrel contains 42 gallons. Throughput totals reflect crude oil inputs (gross standard volume) into Pump Station 1.
