FIguRE 15.9 The Sakhalin 2 project: (a) fields for both Sakhalin 1 and Sakhalin 2 and
(b) infrastructure for Sakhalin 2. (Source: © energy.fanchi.com (2015).)

P‐A field consists of two hills connected by a valley. The Piltun anticline is in the
north, and the Astokh anticline is in the south.
An international tender for the right to conduct a feasibility study of the two fields
was announced in 1991. The Russian Federation signed an agreement in 1992 with a
consortium of companies (Marathon, McDermott, and Mitsui) to conduct the feasi-
bility study. Royal Dutch Shell and Mitsubishi joined the consortium in 1992. The
consortium established the Sakhalin Energy Investment Company Ltd. (Sakhalin
Energy) in 1994 after the feasibility study was approved by the Russian Federation
in 1993.
A production sharing agreement to develop the Lunskoye and P‐A fields was
signed in 1994 between the Russian Federation in Moscow, the Sakhalin Oblast
Administration in Yuzhno‐Sakhalinsk, and Sakhalin Energy. A Law on Production
Sharing Agreements was enacted by the Russian Federation in 1996. The Russian
Federation then issued licenses to develop the Lunskoye and P‐A fields to Sakhalin
Energy in 1996. Appraisal work on the two fields began in the summer of 1996.
The consortium changed in 1997 when McDermott sold its shares to the other
shareholders. Russian agencies approved the Phase 1 development plan for the P‐A
field in 1997 and the feasibility study in 1998. Phase 1 development called for
installation of the Molikpaq production platform at the P‐A field. The Molikpaq
platform is called the PA‐A platform in Figure 15.9 and is shown in Figure 15.10.
