Recent years have seen an increase in high-speed electric compression for Oil & Gas applications where high-speed electric motors drive compressors directly without intermediate gears. To date induction machines have been the predominant workhorse of the industry. The permanent-magnet machine technology provides an alternative that promises a highly reliable and robust system design, especially in applications where motor and compressor are fully integrated and share the same process gas environment. This paper provides an update on the recent progress in developing the permanent magnet technology for Oil & Gas applications in which the process gas may contain corrosive elements.

The industrial Trent is the largest aeroderivative gas turbine available, at 50+ MW, and the most efficient gas turbine available to industrial and marine operators, at 42%. Its Dry Low Emissions combustion system embodies the features of the similar combustor on the industrial RB211, which is enjoying very successful service experience. Its design features and derivation from the aero engine are reviewed, together with an assessment of the maintenance aspects of the engine. The current status of the engine validation programme is discussed, covering both component rig testing and progress on the full engine testing being carried out in Montreal, Canada. The applications of the industrial Trent are considered by reviewing the major markets and examining its suitability, both technically and economically, for several existing and emerging sectors. Launched as a power generation machine, the industrial Trent is shown to be well suited to those sectors which have resulted from the growing deregulation of this industry worldwide. In addition it is shown to be attractive for certain applications in the oil and gas industry and, in the marine market, for some large high speed vessel concepts.

There have been reports of strong submerged jet currents in the Gulf of Mexico in recent years which have implications for the design and operation of some offshore facilities. This paper describes the methodology and results of a screening study which searched for such events within the extensive body of recent data collected by the offshore oil and gas industry, made available on the NOAA National Data Buoy Center web site. This study was conducted on behalf of a consortium of industry clients with participation by relevant US government bodies. After a first phase investigation, initially well defined screening criteria were revised to avoid the numerous events triggered by clearly invalid data and the potential for missing some critical submerged events. The automatic screening criteria were replaced by manual event selection based on plots showing all available data. The identified events fall into the following broad categories: • Submerged speed peaks due to inertial period currents, most notable after the 2005 hurricanes. • A few submerged jet like events isolated in time with no clear periodicity. • Submerged speed peaks with high vertical and error velocities and often incoherent structures. • Persistent high speed currents near the limit of the ADCP range.

Common Operation

Pigging is a common operation in the oil and gas industry. Because of the compressibility of the gas, starting up a pipeline inspection gauge (pig) from a stoppage can generate a very high speed of the pig, which is dangerous to the pipe and the pig itself. Understanding the maximum speed a pig achieves in the restarting process would contribute to pig design and safe pigging. This paper presents the modeling of a pig restarting from a stoppage in gas pipeline. In the model, the transient equations of gas flow are solved by method of characteristics (MOC). Runge-Kutta method is used for solving the pig speed equation. The process of a pig restarting from a stoppage in a horizontal gas pipe is simulated. The results indicate that the maximum speed a pig achieves from a stoppage is primarily determined by the pressure of the pipe and the pressure change caused by the obstructions. Furthermore, response surface methodology (RSM) is used to study the maximum speed of pig. An empirical formula is present to predict the maximum speed of a pig restarting from a stoppage in gas pipeline.

Reactive power has a significant impact on the parameters of the power supply system in the oil and gas industry; as a result, there is a decrease in the quality of the electric network. The relevance of the study is justified by the tasks of improving the quality of electricity in the load nodes consisting of asynchronous motors, one of which is the reactive power compensation, including the calculation and automatic regulation of compensating devices. The aim of the article is to design and research a reactive power compensation control system to improve the quality of electricity. The article proposes a solution to the actual problem of reactive power compensation based on the proposed power quality control algorithm. The system of automatic control of reactive power compensation developed in the Matlab and Simulink software package allows us to generate parameters according to current measurements and adjust the voltage when the load operation mode changes. The use of MOSFET transistors in the control system made it possible to create the necessary compensation currents with a low content of higher harmonics that create distortions in the supply voltage and ensure high speed of the reactive power compensation unit operation.

A comparison of the properties of rubbers, that are mainly used as materials for the manufacture of seals used in the oil and gas industry, is presented. These are technical vulcanized rubbers based on the following rubbers: ethylene-propylene diene, butadiene-acrylonitrile, hydrogenated butadiene-acrylonitrile, fluoroelastomer, tetrafluoroethylene propylene, perfluoroelastomers. Their resistance to the action of physical and chemical factors that determine the properties of working environments is assessed: the temperature range of working capacity, resistance to ozone and aging under the influence of atmospheric factors, chemical resistance to the action of materials of working environments. The list of environments to which the considered rubbers are resistant and not resistant is given. Resistance to high-speed gas decompression has been noted. For rubbers based on tetrafluoroethylene propylene and perfluoroelastomers, the possibility of using them for work in vacuum is indicated. It is concluded that, despite the high cost, rubbers based on tetrafluoroethylenepropylene and perfluoroelastomers have the best set of properties for operation in the oil industry.
