Intensive Development

Prospects for the further development of the oil and gas industry are mainly associated with the development and commissioning of high-rate fields. In this regard, the production of more economical and durable equipment by machine-building enterprises, an increase in the level of its reliability and competitiveness, as well as further improvement of technological production processes, is of paramount importance. The evolution of technology in a broad sense is a representation of changes in designs, manufacturing technology, their direction and patterns. In this case, a certain state of any class of TC is considered as a result of long-term changes in its previous state; transition from existing and applied in practice vehicles to new models that differ from previous designs. These transitions, as a rule, are associated with the improvement of any performance criteria or quality indicators of the vehicle and are progressive in nature. The work is devoted to the study of the evolution of the quality of high-pressure valves during the period of their intensive development. Keywords: technical system, evolution of technology, high-pressure valves, shut-off devices, gate.

Component Selection

Harsh Environment approved components/ designs require high reliability as well as availability of power to meet their system needs. The paper will explore the various design constrains imposed on the high temperature designs. Down hole oil and gas industry requires high reliability components that can withstand high temperature. Discrete component selection, packaging and constrains imposed by various specification requirements to meet harsh environment approval are critical aspect of high-temp designs. High temperature PCB material, PCB layout techniques, trace characteristics are an important aspect of high-temperature PCB design and will be explored in the article. Buck Converters are the basic building blocks, but in order to meet system requirements to power FPGA's where low output voltage and high currents are required. Converter must be able to provide wider step down ratios with high transient response so buck converters are used. The paper with explore the various features of a buck-based POL converter design. Low noise forces the need for Low-dropout (LDO) Regulators that can operate at high Temperatures up to 210°C. This paper will address the power requirements to meet system needs.

Abstract The decline of easily accessible reserves pushes the oil and gas industry to drill deeper to explore previously untapped wells. Temperatures in these wells can exceed 210 °C. Cooling and conventional heat extraction techniques are impractical in such a harsh environment. Reliable electronic designs that can sustain high temperature become necessary. This paper presents RF and IF microstrip combline band-pass filters for downhole communications, which can reliably operate up to 250 °C. Both filters are prototyped on a Rogers RO4003C substrate. Measured results at 250 °C show that the RF and IF filters have insertion losses of 4.53 dB and 3.45 dB, respectively. Both filters have stable performance at high temperatures. The maximum insertion loss variation with temperature for the RF filter is 1.88 dB, and bandwidth variation is 1.3 MHz. The maximum insertion loss variation with temperature for the IF filter is 1.48 dB, and bandwidth variation is 0.4 MHz. Return loss for the RF filter is more than 12 dB, and for the IF filter more than 10 dB in the passband. This paper also describes a simple method to find spacing between coupled symmetrical microstrip lines of a combline filter.

Project Location

Due to increasing demand for energy around the world, the prevalence of global megaprojects within the oil and gas industry is increasing. Process pipes, valves and vessels may be manufactured and coated in China or Korea, where labour costs are comparatively low, before being transported to the final project location, such as Western Australia. During the transport and fabrication phase, coated steelwork may spend months or even years exposed to harsh offshore or coastal environments before going into service. This means coatings must be able to provide protection throughout an extensive construction phase, in addition to the in-service lifetime of the steel. This paper examines the demands on high temperature performance coatings both before and once in service. Test methodology and exposure data are reviewed with a focus on how modern aluminium pigmented silicone coatings provide a solution to the corrosion challenges faced in global megaprojects.

Cement Sheath

During oil and gas development, high pressure, high temperature and non-uniform earth stress increase the complexity of stresses in well bore which is composed of casing, cement sheath and formation. In order to obtain well bore stresses in hostile conditions, a new model is established with cement sheath and formation are treated as different materials. To predict well bore stresses rapidly, stress conversion coefficients are obtained that may change loads into stresses at key points conveniently.
