Detection of dissolved methane and volatile hydrocarbons in water is a problem met inleakage localization during exploitation of underwater pipelines, oil and oil product spill over watersurface, geological exploration work for the localization of oil and gas fields under water, etc. Thisproblem can be solved by the application of detection system based on tubular selective membranepermeable for volatile organics and impenetrable for liquid water. Carrier gas (air) flowing throughthis tube is saturated with dissolved gas and then gas concentration is measured usingsemiconductor or other gas sensor. The system prototype was tested under laboratory conditionsand demonstrated low limit of gas detection (~20 ppb by mass of dissolved methane in water) andshort response time (~10 s).

The necessity of the complex approach is defined for increase of reliability of the oil and gas equipment operated under pressure of hydrogen sulfide-containing medium, including: - control at the stages of design, manufacturing, commissioning, operation, repair and reconstruction; - organization of corrosion service; - rational choice of materials for equipment manufacturing and its repair; - use of different methods to protect equipment against corrosion: - diagnostics of equipment and evaluation of corrosion protection efficiency; - conducting corrosion tests of materials and corrosion control. The trend of increasing corrosive activity of the products of a number of hydrogen sulfide-bearing oil and gas fields is described. This is associated with their watering and contamination by sulfate-reducing bacteria. All types of corrosion-mechanical damage of steels in accordance with GOST R 53679-2009 (ISO 15156-1:2001) are considered. Comments are given on each of these types of damage and the types of steels that are prone to these defects are shown. The recommendations of GOST R 53679-2009 (ISO 15156-1:2001) are given for the selection of steel equipment operated under pressure of hydrogen sulfide-containing media depending on the type of their corrosionmechanical failure, with comments. Requirements for the use of steels modified with rare-earth metals (REM) and alkaline-earth elements (ALE) intended for operation in hydrogen sulfide-containing media are given.
