AbstractMiniaturized single-mode thickness-shear pressure transducer combined with high-temperature SOI, silicon on insulator, integrated circuit technology is proposed as network-ready high-pressure high-resolution smart sensor for distributed data acquisition in oil and gas production wells. The transducer miniaturization is investigated with a full 3D computer model previously developed by the authors to assess the impact of intrinsic losses and various geometrical features on transducer performance. Over the last decades there has been a trend toward size reduction of high-resolution pressure transducer. The implemented model provides insight into the evolution of high-resolution pressure transducers from Hewlett-Packard™  to Quartzdyne™  and beyond. Distributed measurement in production oil wells in extreme harsh environment, such as found in the pre-salt layer, is an unsolved problem. The industry move toward electrified wells offers an opportunity for application of smart sensor technology and power line communications to achieve distributed high-resolution data acquisition.

A full 3D computer model is developed to evaluate the performance impact of intrinsic loss and various geometrical features in high-resolution pressure transducer. The intrinsic loss is modeled as viscosity factors, which allows for a more efficient computer model. In this paper, the developed model is applied to yield an insight in the evolution of high-resolution down-hole pressure transducer, from Hewlett-Packard\texttrademark\, to Quartzdyne\texttrademark. As the quality factor is related to the inverse of the resolution, the transducing element optimization process to achieve the highest quality factor possible is investigated, considering the impact of crystal quality and geometrical features, such as: thickness, diameter and convexity (plano-convex and bi-convex). Temperature-dependent elastic constants are used to improve the model accuracy in modeling temperature effects on the vibrating resonator-type transducer. Boundary load conditions are used to simulate hydrostatic pressure. The simulations to extract the frequency shift are carried out in the range of $14\,psi$ ($96.5\,kPa$) to $20000\,psi$ ($137.89\,MPa$) and $0\,^oC$ to $200\,^oC$ for pressure and temperature, respectively, as such ranges are typically found in oil and gas wells. A discrepancy in the published temperature dependence has been found. A miniaturization path to achieve semi-distributed measurement in oil and gas production wells is presented.

The Impact

The development of wet gas compressors will enable increased oil and gas production rates and enhanced profitable operation by subsea well-stream boosting. A more fundamental knowledge of the impact of liquid is essential with regard to the understanding of thermodynamic and fluid dynamic compressor behavior. An open-loop impeller test facility was designed to investigate the wet gas performance, aerodynamic stability, and operation range. The facility was made adaptable for different impeller and diffuser geometries. In this paper, the wet gas test facility and experimental work concerning the impact of wet gas on a representative full-scale industrial impeller are presented. The centrifugal compressor performance was examined at high gas volume fractions and atmospheric inlet conditions. Air and water were used as experimental fluids. Dry and wet gas performance was experimentally verified and analyzed. The results were in accordance with previous test data and indicated a stringent influence of the liquid phase. Air/water tests at atmospheric conditions were capable of reproducing the general performance trend of hydrocarbon wet gas compressor tests at high pressure.

The Impact

Subsea oil and gas production involves assemblies such as trees, manifolds, and pipelines that are installed on sea floor. Each of these components is exposed to severe working conditions throughout its operational life and is difficult and expensive to repair or retrieve installed. During installation and operation, a rig/platform and several supply vessels are stationed on the waterline directly above the well and installed equipment below. If any object is to be dropped overboard, it presents a hazard to the installed equipment. A subsea tree comprises of a number of critical components such as valves and hydraulic actuators, in addition to several electrical components such as the subsea control module and pressure/temperature gauges. Their ability to operate correctly is vital to the safe production of oil and gas. If an object were to impact and damage these components, resulting in their inability to operate as intended, the consequences could be severe. In this paper, a typical subsea tree frame is analyzed to ensure its ability to withstand the impact from an object accidentally dropped overboard. This was accomplished using nonlinear dynamic Finite Element Analysis (FEA). In this study, the framework was struck by a rigid body at terminal velocity, resulting in a given impact energy. Displacements and resultant strain values at critical locations were then compared to allowable limits to ensure compliance to the design requirements.

The Impact

The article presents the results of the author’s research of the impact of a wide range of restrictions and prohibitions applied to theRussian Federation, used by a number of countries for their geopolitical purposes and as a means of competition. The object of study was the impact of anti-Russian sanctions on the development of Oil & Gas industry and defence industry complex ofRussiain 2014–2016. The purpose of the analysis was to assess the impact of sanctions on the volume of oil and gas production, the dynamics of foreign earnings from the export of oil and gas, and of foreign earnings from the sale abroad of military and civilian products of the Russian defence industry complex (DIC). As the research method, the author used the economic analysis of the time series of statistical data presented in open statistics and literature. The author showed that some countries use the anti-Russian sanctions as a means of political, financial, economic, scientific, and technological struggle with the leadership ofRussiaand Russian economic entities. It is noteworthy that their introduction in 2014 coincided with the readiness of theUSto export gas and oil, which required a niche in the international energy market. The imposed sanctions have affected the volume of oil production inRussia, which was one of the factors of reduction of foreign earnings from the country’s oil and gas exports. However, the Russian defence industry complex has relatively well experienced the negative impact of sanctions and other non-market instruments of competition

We consider modeling and geophysical interpretation of the obtained results in the oil and gas production problems. For solving these practical problems, we use combined finite element-differences method of resolving piezoconductivity problem with calculation of heterogeneous filtration parameters distribution of oil and gas productive reservoirs and oil-gas penetration conditions in the borders of the reservoirs. At that, we consider the main factors, which influence on the intensity of filtration processes near oil production well and gas production well respectively. These factors are important for effective supporting in practice high level of the oil and gas production. On the base of computer modeling, we have showed that intensity of filtration process near the acting oil and gas production wells mainly depends on oil phase and respectively gas phase permeability, as in close zone of well acting so in remote zone. The viscosity and reservoir porosity parameters in close and remote zones of the well action have little direct effect on filtration process near the acting well. However, these parameters can influence on the filtration process implicitly via direct acting on the respective phase permeability. We also have carried out analysis of the pumping well influence on the filtration process near production well in different practical cases.
