Argillites of the Exploration Formation of the Talnakhskoye field, known as "shooters", often collapse in the borehole of drilled wells. Previous studies have focused on identifying the causes of argillites instability, studying their mineral composition ...
Borehole penetration of mudstones of the Exploration Formation of the Talnakhskoye field is often complicated by collapse of borehole walls. The strong tectonic disturbance of the area and high rock pressure due to the great depth (2000 m) of the formation do not fully explain this phenomenon, since both emergency and accident-free wells have been recorded in equal conditions ...
В настоящей работе приведены результаты исследования строения верхних (в диапазоне 0-250 м) горизонтов толщи антарктического льда с участка, находящегося в 50 км к югу от станции Мирный. Материалом исследования служил керн льда диаметром 180 мм, полученный из вертикальной скважины ...
