The air injection process (AIP) has been widely applied to enhance crude-oil recovery. In the last decades, the limited understandings of the oxidation mechanisms complicate the prediction of the performance of AIP. The vapor-phase reaction of…
The air injection process (AIP) has long been applied to enhance crude oil production. During an AIP, the injected air reacts in-situ with part of the crude oil, generating heat and flue gas, and thus displacing the other portion of the crude oil.…
In modern internal combustion engines, along with the forces from the gas pressure in the pistons, the inertia forces and inertia torques of the crank mechanism occur. These values depend on masses and accelerations of elements of the crank…
It has been established that the separation of gas inclusions in crude oil before supplying to the oil pipeline is actual. The process of oil separation based on the magnetohydrodynamic effect should include not only an increase in pressure, but also…
The origins of naturally occurring and man-made radioactive sources are described, and their contributions to exposure to radiation are identified. Naturally occurring radioactive materials that become sufficiently concentrated by processing and…
Oil spill effects on environments and habitats can be catastrophic, where they can kill plants and animals, disturb salinity/pH levels, and pollute air/water. The aim of this work was to accelerate the biodegradation of crude oil by combination with…

The easy detection of fouling in duct systems is a persistent problem and remains a relevant demand for the chemical, oil, food and pharmaceutical industries. This work presents preliminary research results of vibrational hammer excitation for easy…
Pipeline inspections are essential for an updated diagnosis in Oil and Gas Industry, but manual inspection in remote areas implies great expenses in the long term. Therefore, this process optimization requires autonomous and versatile systems, such…
The gas pipe in shield is one of the key parts of the long distance pipeline projects. It brings a great deal of uncertainty and risk factors for pipeline pigging operations. Paper establishes the finite element model, analyzes pig pigging and the…
The intelligent PIG's is denominated by this way because it is implemented in them electronic, mechanics, ultrasonic, or electromagnetic systems, that allow to know the physical state of the pipe that they travel. The present work describes the…
Wireless sensor networks (WSN) provide a powerful solution to the task of monitoring the operational conditions of buried and non-buried pipes of different lengths and materials. Due to the limited energy stored in the sensor nodes, the use of…
The minimum rated thruster capacity is determined for assisting LNG Vessel (LNGC) berthing operation during holding mode, where thrusters are expected to provide lee-side area for the LNGC and tug boats by rotating the Floating LNG (FLNG) against…
Fuel consumption and air pollution caused by transportation is becoming more and more serious. Developing an effective meso model to analyze dynamically the temporal and spatial distribution of fuel consumption in the urban road network has become a…
This paper presents the design, implementation and test results of an online system for instantaneous measurement and display of fuel consumption in a vehicle. By utilizing the existing available sensors for input, the overall cost and complexity of…
Auto-rickshaw is an important para-transit mode of urban transportation in India. Cheap in fair but old technology and adulterated fuel quality make it emission intensive. Therefore, this study is aiming the emission assessment of most demanding mode…
This paper proposes a robust day-ahead scheduling method for a multi-carrier energy system (MES), which would enhance the flexibility of power systems with a large sum of variable wind power. We build an MES model and propose an optimal MES schedule…
The main goal of the described project was to develop useful models of behaviour of waterproof plugs in the cavern gas storage. The models are intended for facility operators that compare the real behaviour of plugs with the models. The models are…
Oil spilled on water undergoes alteration by physical, chemical, and biological processes. Rapid physical processes include spreading, movement with winds and water currents, evaporation of volatile components, solution, water-in-oil emulsification,…
The fluctuations of the price of crude oil is pushing the oil companies to increase the investments in seismic exploration of new oil and gas reservoir. Seismic exploration requires a large number (500 divide 2000 nodes/sqkm) of sensors (geophones or…
Recently the world has seen an explosion of available data, gathered from sensors, experiments and direct measurements. The engineering world is shifting from model-centred simulations to the exploitation of large datasets for insights into machine…
