15 Project schedule of well construction Purchase of inventory and services, preparatory work Aggregated plan of works for well construction Start of SSDR mobilization Towing of SSDR PSV mobilization SSDR installation Drilling of the well Start of SSDR demobilization Testing of the well A key project management tool detailed network schedule of the project, planned with the reserves at the time Monitoring of the drilling process on the basis of the graph "depth/day Monitor production and support processes with regular reports on the project, which also allows to quickly interpret the results of the drilling Elimination Towing of SSDR to the port September 16 - March 17 April May June July August Septembe r October 15

16 Effective process of well construction: drilling rig and technical solutions 1 Drilling rig selection 2 Technical solutions selection Fitted with a state-of-the-art drilling and process equipment In 2014 the rig was retrofitted. In 2017 the rig was additionally retrofitted to comply with the climatic and met-ocean conditions of the Sea of Okhotsk SSDR fully complies with the latest Russian and international industrial and environmental safety standards SSDR «HAKURYU-5» Shallow depth to set the rig handled using the anchor type retaining drilling Taking into account the potential complications of the upper part of the section (subsurface gas), standard technological approach to the drilling of the upper intervals was not applicable In this regard, the project team chose the list of technical solutions that have proved their efficiency in the drilling process: riser less drilling drilling a pilot hole a certain type of mud 16

17 Korsakov Sea Commercial Port - integrated center for marine operations support of for the Project Achievements Integrated center for marine operations support Dispatch service Sufficient depth of the approach channel Train unloading unit Areas for development Transportation of ionizing radiation sources Expansion of the zone of temporary storage under customs control Installation of emergency diesel generators in the southern district 17

18 To ensure the logistics operations of the Project, the optimal configuration of the vessels has been defined 2 transport & towing vessels (AHTS) 2 supply vessels (PSV) 1 rescue vessel Powerful (pull force of 275 t) modern vessels with hybrid power plants attracted from the Norwegian market Perform operations for the towing and fsetting/removing the rig on the drilling site, deliver materials and equipment Have the ability to transport personnel Approved for transportation of ionizing radiation sources Achievements New economical vessels attracted from the Asian market Carry out removal of drilling waste, transportation of materials, equipment and personnel 1 ship of 2 was drawn only for the period of active work at the beginning of the project (the first 76 days) Areas for development Modern vessel of the f Rosmorrechflot fleet, Russia Carries emergency rescue duty The selected configuration of vessels allowed safely, promptly and effectively to support project by materials, equipment, personnel Further work with market owners to reduce the rates for vessels attract Study of the alternative variants of ionizing radiation sources transportation (helicopter) 18

19 Safety and environmental awareness the main priority during shelf projects development 19

20 Safety and environmental awareness priority at Ayashskaya-1 projects implementation Achieved HSE results The plan of liquidation of emergency oil spills Warning system of oil spill, rescue duty Implementation of the principle "zero discharge Applicability of the s best practices in HSE to suppliers and contractors Plans for 2018 Co-financing of the Red Book publication of the Sakhalin region Custody of animals in Zoological and Botanic Park of Yuzhno- Sakhalinsk Carrying out of the scientific study of the biological diversity within Ayashsky license block Safety business is successful business! 20
