Drilling Operations The Company is capable of executing onshore drilling of oil and gas wells on a wide range of depths and under difficult geological conditions. It possesses technical know-how and ability to meet the most stringent customer requirements in the following areas: Drilling in high-pressure zones applying technologies permitting high-accuracy control of differential pressure. Drilling under saline deposits using efficient technologies of chemogenic stratum penetration (strata with brine inflows, salt distortions and other anomalies). Drilling on fractured and rough terrain. Well casing and cementing operations under extreme geo-technical conditions, such as salt distortions, brine and other high-pressure inflows (including H2S), large caverns,...
