Big data analytics (BDA) applications are software applications that process huge amounts of data using large-scale parallel processing infrastructure to obtain hidden value. Hadoop is the most mature open source BDA processing framework, which…
Leakage is the most important factor for unaccounted losses in any pipe network around the world. However, most state of the art leak detection systems have limited applicability, lack in reliability and/or depend on user experience for data…
Scope: This part of ISO 20765 specifies a method to calculate volumetric and caloric properties of natural gases, manufactured fuel gases, and similar mixtures, at conditions where the mixture may be in either the homogeneous (single-phase) gas…
Non-equilibrium phase behavior of hydrocarbons has a great influence on the development of gascondensate and oil and gas condensate deposits, as well as oil deposits after evolution of dissolved gas.The key parameter of mathematical models that take…
Reservoir permeability is a crucial parameter for reservoir characterization and the estimation of current and future production from hydrocarbon reservoirs. Permeability can be conventionally estimated from traditional approaches such as core…
The current state of the Russian oil industry requires a scientific approach to optimizing the operation of electrical submersible pumps (ESPs) in harsh conditions. Most of the fields are at a late stage of development with high watercut and…
Accidental leakages in underwater natural gas pipelines pose significant risks for the environment. Therefore, it is essential to estimate the leakage rate and monitor the methane diffusion range outside the pipeline, which is challengeable due to…
Reliable estimate of the anelastic attenuation factor- Q from seismic records is highly desirable for improving seismic resolution. However, the conventional equivalent- Q or horizontal interval- Q estimation ignores that Q-distribution should hold…
This paper presents the design of soft sensors for estimation of froth quality in oil sands extraction processes. One of the most important quality indexes for bitumen froth is the water content. Due to the variations of oil sands compositions and…
This thesis introduces basic theory of stress wave test, proposes orientation of tri sensor based on time delay estimation of Hilbert Transform and its application in stress wave test.
Time-delay estimation (TDE) for thin top layers of asphalt pavement is a challenging task due to the limited resolution of ground penetrating radar (GPR) as well as small permittivity difference between top layers. Echoes backscattered from the…
