Laser Systems for the Pollutants Control in the Oil and Gas Industry

Abstract

Abstract The questions of the laser technologies application in oil and gas industry and the scope of laser systems for the atmosphere, sea and underground waters control are considered in this article. Options of creation and using of the lidar for environmental monitoring, technological control and search of the hydrocarbons fields in various natural and technogenic conditions are offered. The main attention is paid to the Raman lidar for the sensing of the oil hydrocarbon molecules in the atmosphere. It is shown that such a lidar measurement time for the 1015 cm−3 concentration of the studied molecules at the ranging distance up to 200 m doesn’t exceed 265 microseconds. Creation of the fluorescent lidar for the sea water and the underground waters of the coastal area monitoring will allow to solve a problem of their pollution. Recording of the pollutants concentration spatial distribution can serve as the basic data for the solution of the inverse problem of the identification of pollution sources. The suggested methods have simple hardware realization and allow to diagnose the high-concentrated flows of the weighed particles and also hydrocarbons in the sea and underground waters.
