Ensuring consistent business unit involvement in new technology development and implementation: Gazprom Neft approach

Abstract

Выполнен обзор исследований в области разработки и применения магнезиальных цементов. Указаны их преимущества и недостатки. Особое внимание уделено составам, предназначенным для крепления глубоких нефтяных и газовых скважин в солесодержащих разрезах. Показана возможность крепления скважин в многолетнемёрзлых породах с использованием магнезиального вяжущего. Ключевые слова; магнезиальный цемент, крепление скважин, солесодержащий разрез, многолетнемёрзлые породы. Review of research in the field of magnesia cements development and usage was carried out. Their advantages and disadvantages are described. Much attention has been given to compositions for deep oil and gas well casing in salt-containing crosssection. An opportunity that the magnesia cements can be used for casing in permafrost is showed.

Oil deposits of the Visean stage of the northeastern part of the Tatarstan Republic

“…The deposits of the Visean stage on the territory of the Volga-Ural anteclise are regionally oil-bearing [1][2][3]. According to some estimates, about 35% of all explored oil reserves are concentrated within the Republic of Tatarstan [4]. The most promising oil reservoirs are associated with sandstones of the Tulian-Bobrikian age, which form reservoir layers or perform erosion incisions within the South Tatar arch and the Melekess depression [5][6][7][8].…”
