Construction of a Multipurpose Exploration Well in the Jurassic Deposits Subsequent Transfer to Production Enabled by Metal Expandable Barrier Installed Behind the Casing

The resource base of the north of the West Siberian oil and gas province is the basis of Russia's energy strategy. Among the northern territories of the province, the Nadym-Purskaya, Pur-Tazovskaya and Yamal oil and gas regions (OGRs) are the leaders in terms of estimated gas reserves (Figure 1). However, the largest deposits of the first two OGRs are in the stage of falling production. Therefore, the main prospects should be associated with the Yamal OGR, which has not yet been put into active operation. It is logical that along with the development of traditional methods of extraction of "dry" natural gas, the government of the Russian Federation has approved a plan for the production of liquefied natural gas based on the fields of the Yamal Peninsula, which is currently being actively implemented by PJSC "NOVATEK".
