Abstract

Geographically offshore oil industry has expanded to a scale when one does not need to go beyond the Arctic Circle in the Barents Sea to face cold weather, presence of ice and severe operating conditions while drilling and well construction. Northern Caspian Sea region has very sensitive environment and harsh weather conditions, where ice floes up to 1 m thick can be observed around offshore installations. Workshop-based multiple ice testing, ice protection, closed loop cooling circuit and zero discharge are standard design criteria for all offshore installations. In our opinion this experience and practice is relevant for future Arctic areas development projects.

Barents Sea on the Norwegian Continental Shelf (NCS) proved to be a perspective oil region, but a lot of potential in the promising Permian and Carboniferous carbonate reservoirs is yet to be confirmed, though recent discoveries give a lot of hope to the industry and the region itself. One of the demanding issues on the agenda is well control, integrity and hole stability while drilling and coring through carbonates. Accumulated historic operational drilling and well experience from carbonate fields in Timan-Pechora region is valuable to facilitate accurate decisions for similar fields in the Barents Sea. Due to hole stability issues additional well design criteria are dedicated to rock and geo mechanics. Most challenges encountered when drilling extended reach production wells with focus on stresses around the wellbore. Drilling through carbonates significantly increases chances for mud severe losses and may cause well going out of control. Timan-Pechora oil province dates its history back to 1930 with a large share of unconventional (heavy oil) reserves in some of the fields. Thus, drilling shallow horizontal wells may be used as a relevant analogue for shallow reservoirs in the Barents Sea of the NCS. Year-round operations in the harsh weather conditions with presence of ice floes and longstanding drilling and completion experience through carbonates combined will provide a basis for analogy and may potentially mitigate uncertainties and risks while drilling exploration and production wells in the Barents Sea. Logistics and transportation solutions of the year round operations at the Varandey offshore oil terminal in the Barents Sea is a good example how development of oils fields in the icy Arctic region can be successfully performed.

During this lecture, an overview of the company LUKOIL and its activities will be given briefly. Geological basis and assumptions will be used to facilitate the discussion on challenges and potential synergies.
