PROCEDURE OF GEOCHEMICAL SURVEY OF WATER AREA AND GEAR FOR ITS IMPLEMENTATION Russian patent published in 2002 - IPC

FIELD: geochemical survey to predict oil and gas fields under floor of water area with continuous profiling from specialized vessels. SUBSTANCE: uninterrupted control over constancy of conditions of sample taking with due account of dynamics of vessel's motion, control over speed of flow of water in water line of deaerator, control over rate of supply of carrier gas, realization of synchronous accurate coordinated referencing of observation points and discreteness of analysis of consistent samples of water depending on vessel's speed are executed. EFFECT: increased accuracy, informativity and authenticity of measurements and interpretation of continuous measurements on moving vessel. 9 cl, 5 dwg
