The Australia-Indonesia Zone of Cooperation Treaty entered into force
on 9 February 1991. The event not only marked a new chapter of the dev
elopment of the bilateral relationship between the two countries, but
also heralded the birth of a regime to allow joint development of the
petroleum resources in an area where the sea boundary is subject to co
mpeting claims. This regime consists of a ministerial council and a jo
int authority. The former oversees all the policy issues relating to t
he implementation of the treaty, while the latter administers petroleu
m operations in area A of the zone of cooperation. Eleven production s
haring contracts for area A were signed by February 1992. The contract
ors have committed themselves to an exploration expenditure of at leas
t US$200 million for the period from 1992 to 1994, including the drill
ing of 23 wells. Exploration activity to date has involved the acquisi
tion and analysis of seismic data and drilling operations commenced in
December 1992. Area A, including the Kelp structure, is perceived to
have a high prospectivity.
