This Paper describes the on-going efforts of finding the root-cause for the failures of high-energy (over 30,000 HP), high-pitch velocity (over 30,000 FPM) gear elements. These gear elements are presently operating in Oil and Gas Production Facilities. They are installed between the GT drivers and turbo-compressors. Turbo-compressors deliver high-pressure gas into the underground oil fields to enhance the oil production. The oldest Gas Compression Units were commissioned in 1995 and the latest in 1998. Since installation in 1995 at least 6 gear boxes experienced failures of the pinion (high speed gear) teeth. The Mean Time Between Failures (MTBF) of the pinion teeth was estimated around 34,000 operating hours. The costly shutdown of Gas Compression Units forced the management to seek advice within the company. The intent of this Paper is to share some field experiences and to present some corrective actions. The intent of this Paper is also to help Original Equipment Manufacturers (OEMs) in this case gear elements Manufacturers to develop better balance between cost, life and reliability. Sometimes the balance between these three parameters is difficult to maintain. Too often the gear elements Manufacturers are forced to compete on the price basis and as result the quality of the gear elements are sometimes compromised. In addition, several well-known gear elements Manufacturers stopped offering high energy, high-pitch velocity gear elements because they suffered serious failures of the gear elements on the test stand and also in the field.

This Paper describes continuation of efforts to improve the low reliability of the high power, high pitch velocity gear boxes. These gear boxes are located in oil and gas production facilities (OAGPF) and serve to transmit the power from gas turbine drivers to large, two or three case turbo compressor trains. Life expectancy of these gear boxes did not meet predicted life expectancy of typical high speed, high energy gear boxes. This paper deals with various modifications of these gear boxes which were necessary to improve very low, initial 34% reliability. The series of modifications improved gear boxes life expectancies, however they never reached desired goal that is at least 10 years of continuous service without gear elements failures.

Settling Process

Abstract Hydraulic fracturing is an important technology to improve oil and gas production. In recent years, rod-shaped proppant has received increasing attention for its advantages in avoiding fracture closure and enhancing conductivity. Due to its special shape, the settling process in the fracture is more complicated than that of a spherical proppant. Accurate description of the wall factor of fracture on the settling rod-shaped proppant is pivotal in predicting the transport distance of rod-shaped proppant and improving the effect of fracturing. However, few researches have been reported about the fracture wall factor on the settling rod-shaped proppant. In this study, the transparent fracture model with different width and a high-speed camera were used to record the settling process of the rod-shaped proppant in the fracture. A total of 215 tests were carried out to analyze the effects of fluid properties, the equivalent dimensionless diameter, sphericity, and Reynolds number on the wall factor, involving the ranges of the equivalent dimensionless diameter and the particle Reynolds number are 0.03 to 1.47 and 0.03–1354.14, respectively. The settling processes of rod-shaped proppant under horizontal and vertical states were studied, and two wall factor models for the two states were established, respectively. The results show that the wall factor is a function of both the equivalent dimensionless diameter and Reynolds number. Finally, the prediction models of wall factor with the prediction error of 1.70 and 4.44% are established for these two Reynolds number regions, respectively. The results of this study can further improve the performance of rod-shaped proppant in hydraulic fracturing.

The modern world is a complex mechanism in which each process, direction, sphere of activity, despite visual differences, ultimately creates a single complex element aimed at ensuring human life. One of the key processes occurring on the planet is the extraction of hydrocarbons. The article proposes to consider a solution that will contribute to ensuring the efficiency of oil and gas production processes, will extend the life cycle of mature oil and gas production assets of the Russian Federation (hereinafter referred to as the RF) and extend their economic profitability. Economic and technological efficiency from infrastructure reengineering measures is individual for each region, and directly depends on the volume of oil, water production and the state of the ground infrastructure. The described areas of infrastructure reengineering, in aggregate, represent an effective tool for optimizing operating and capital costs, increasing the reliability of technological equipment, removing infrastructure restrictions, which will contribute to the achievement of the set task - maintaining oil production at mature assets. Keywords: facilities for oil treatment; gas compression; reservoir pressure maintenance; power supply; engineering networks; operating costs; reengineering.

The reliability of road transport is one of the main factors affecting the operational capacity and special works performance of any road transport company. The efficiency of task performance directly depends on the uninterrupted operation of vehicles at the site of operation. The authors of the study collected data of MTBF of special trucks Ural 4320 for six transmission elements: gearboxes, transfer gearboxes, clutches, cardan shafts, front and rear axles. The numerical values of the main uptime indicators are determined and their functional dependences on the MTBF are obtained. According to the graphic representation of the functional dependences and variation coefficients, the law of distribution of random variables is determined.

Abstract High Velocity Oxy Fuel, (HVOF), is a high energy Thermal Spraying Combustion Process, producing high density coatings with hardness values in excess of 1200 VPN. Such coatings, using metal carbide spray material, are used extensively in the aerospace industry, in areas where high wear resistance is particularly important. The Linde Detonation Gun, CD-Gun'), has until recent times been the predominant system for applying these hard faced coatings. However, the advent of a number of new HVOF systems approximately 5 years ago, allowed Gas Turbine Repair and Overhaul bases the opportunity to offer a more competitive coating service, i.e. these "1st generation" HVOF systems allowed the development of comparable, if not superior coatings to these produced by the D-Gun. Having successfully developed and approved HVOF coatings for the use on Rolls-Royce Gas Turbine components for both Repair and New Manufacture, Rolls Wood Group addressed the problem of transferring HVOF technology from aerospace components to alternative markets, i.e. refurbishment of equipment used in Oil and Gas Production.

The BRICS countries are increasingly expanding multilateral forms of cooperation, moving beyond political areas to economic ones. This cooperation is based on their interest in using the resources and experience of other partners to the group to develop national economies and promote the export of goods, technologies and services for the benefit of national producers. The purpose of the study is to analyse the potential and identify the most promising areas of sectoral cooperation. It was carried out using the methods of comparative and statistical analysis, historical analogies, deductive and expert assessments. Agreed at BRICS summits, national economic strategies set the priorities of sectoral cooperation. Raising the competitive capacity of the BRICS economies is considered today in the context of productivity enhancement, including increasing energy efficiency, improving logistics, innovating technologies. The most promising areas are cooperation in offshore oil and gas production, nuclear power, construction of small hydropower stations, building transport corridors, including the high-speed networks and equipment of the Northern Sea Route. The sectoral priorities also highlight cooperation in the agriculture sector to address food security problems and in the digitisation of all sectors of the economy to take advantage of the opportunities provided by information and communication technologies.
