Main geophysical features for technological calculation were accepted by analogy with developed fields of Timan-Pechora province. Based on experience of development of shore fields similar in geophysical characteristics, it is not right to expect higher oil capacity while drilling traditional directional wells on this particular area. It takes to use such technology in oil production that will provide high well capacity for justifying large costs in development of fields in shallow conditions. That is the reason for making mono- and dual-bore wells with horizontal completion of various lengths while defining potential productivity. If traditional wells are used, primary capacity will be 100-150 t/day. If they are changed to multilateral horizontal drilling, capacity will increase till 500- 600 t/day. Close-together arrangement of estimated units gives an opportunity to consider them as one potential oil- producing complex with united infrastructure. There is an advantage here that objects of development are located near Khylchuyusky and Yuzhno-Khylchuyusky fields and it lets use current project infrastructure including pipelines. Development of potential fields in concerned conditions is going to be made with the help of artificial islands, ice- resistant fixed platforms and, perhaps, using of modern technologies with subsea well ending. Structures located near coast could be developed partly or entirely by drilling horizontal wells. Successes on the sphere of horizontal drilling have added essential changes to development of coastal reserves. Earlier oil deposits were developed with the help of artificial islands, seawalls, docks and plunged platforms, but now it is more rational and cheaper to develop them by drilling directional wells at coast outshore (important condition here is that remoteness from the coast should be not more than 10-12 km). Nowadays there are several examples of super Рис.1. Схема обустройства выделенных структур Печорской губы Pic.1. Scheme of arrangement of selected Pechora Bay structures
