LNG or GTL for North Slope?
The Alaska state government team that examined alternatives for commercialising North Slope natural gas believes a
LNG project is the most promising opportunity, but two large producers want the state to consider a natural
gas-to-liquids (GTL) venture as a viable option.
The Alaska North Slope Gas Commercialisation Team was charged with examining and identifying mechanisms the state
could exercise to encourage development and monetization of the 35 tcf of natural gas known to exist on the North
Slope.
Its report, however, addresses only an LNG project in its economic and regulatory analysis. The project envisioned is
comparable to the proposed TransAlaskan Gas System (TAGS) backed by Yukon Pacific Corp., a subsidiary of railroad
giant CSX Corp.
TAGS would convert about 2 bn cfpd of North Slope gas into 14 mm tpy of LNG. It carries a price tag of about $ 15
bn.
The report notes that an LNG project would add jobs and substantial tax revenues through construction and operations
ofan 800 mile pipeline from Prudhoe Bay on the North Slope to Prince William Sound and an LNG plant near
Valdez.
While producers Exxon and BP were generally supportive of the report, they asked the state not to eliminate GTL
projects from contention.
Both Exxon and BP have their own GTL technology. The third large North Slope producer, Arco has licensed another GTL
technology from Syntroleum Corp.
The GTL plant could be located at Prudhoe Bay, adjacent to the existing oil production facilities, and its products
could be shipped through the existing TransAlaska Pipeline System, eliminating the need for a separate
pipeline.
In their responses to the report, none of the companies indicated specific plans for a GTL project at this time .
