A “hollow cylinder” simulation was performed at TILTS for a number of deposits what allowed us to assess the risks of sand carrying into a well. In particular, such simulation was carried out for the Shtokman field, the largest gas-condensate field located on the shelf of the Barents Sea and Prirazlomnoye field, the only oil field under development on the Russian Arctic shelf (Karev, 2016). Some results of Prirazlomnoye rock tests a presented on Fig. 5. The tests were done for two specimens cut from one piece of core. The graph a) shows the dependence of sand mass carried into the hole on the stress for the equicomponent compression, the graph b) shows this dependence for the conditions when lateral initial stresses equal 0,4 value of vertical rock pressure were simulated. The loading program for the second case is shown on Fig. 6. The pictures of specimens after tests are presented on Fig. 7.

Current Arctic offshore oil and gas exploitation activities are mainly limited to Norwegian and Russian waters. In the Norwegian Arctic, the main developments are the Snøhvit and Goliath fields in the Barents Sea. A third field– the Johan Castberg field – is currently being developed around 100 km northwest of the Snøhvit field. Production there is due to start in 2022 (Equinor 2018). As per (Reuters 2020), exploitation drilling aiming to develop additional new fields on the Norwegian Arctic shelf is expected in the future. In the Russian Arctic, presently, there is a single offshore field under development, known as the Prirazlomnoye field, which is located on the Pechora Sea shelf. The Prizazlomaya field is the only Arctic field in year-round operation using an ice-strengthened offshore platform (Tarovik et al. 2018). Additional fields are expected to be developed in the future as exploration drilling is taking place in the Kara Sea. In the American Arctic, on the other hand, there is currently no offshore drilling. However, this could change as there are strong economic incentives to develop the rich oil and gas fields in the area.
