Maintaining the integrity of pipelines over long distances is an ongoing challenge for oil and gas companies. Among many factors, corrosion is one of the major causes of pipeline failure. Therefore, timely and accurate detection of corrosion is…
Pipe inspection is a crucial process in any industry and it must be regularly done for the smooth and safe functioning of industries. Manual Pipe inspection is a sluggish and labour-intensive task therefore it is recently replaced by using robots.…
With the demand for lower carbon emissions and the increasing use of clean energy instead of traditional fossil fuels, offshore production of liquefied natural gas (LNG) has become a major mode of energy transportation and storage. Due to its…
This paper presents development of a pipeline defect detection (PDD) system and designing main components of the system to reduce the risk of environmental pollution due to pipeline accidents. Main feature presented is a robotic system including a…
Large crude oil tanks may face huge risk during operation due to the effect of dangerous and harmful factors. The leakage and fire accidents of tanks are easy to happen which causes serious environmental pollution and even casualties. In order to…
Photooxidation was an important weathering process for spilled oil at the water surface following the Deepwater Horizon oil spill, leading to the rapid formation of polar or oxygenated hydrocarbons, or photo-generated asphaltenes. While the great…
This study investigated the effect of average carbon number and molecular/bonding characteristics of wax on wax appearance temperature (WAT) and wax crystal shape under microscope. Three samples of SAR, AS, and FAH from oil fields in southwestern…
Traditional gas compressibility factor estimation methods such as AGA8-92DC and SGERG-88 usually use overly complex theoretical derivation and corresponding estimation model. This will cost most of the operating memory of the low-power gas flowmeter.…
In the process of oil exploitation, the water level of an oil well can be predicted and the position of reservoir can be estimated by measuring the water content of crude oil, with reference for the automatic production of high efficiency in the oil…
Due to the exclusive size effect, magnetic nanoparticles (MNPs) exhibit unique chemical, mechanical and considerably different magnetic properties compared with conventional micro and macro materials. Therefore, MNPs are of great significance and…
Reservoir numeric simulation is the most commonly used method for oilfield petroleum production forecasting, but its accuracy is based on accurate geological models and high-quality history matching. In order to overcome the shortcomings of numeric…
This paper describes the data-driven machine learning modeling of the spatial distribution of geophysical parameters in petroleum and gas reservoirs. Multiple kernel learning methods are used to integrate geological information with multi-scale…
Large crude oil tanks may face huge risk during operation due to the effect of dangerous and harmful factors. The leakage and fire accidents of tanks are easy to happen which causes serious environmental pollution and even casualties. In order to…
Hydraulic fracturing produces artificial fractures and creates oil and gas seepage channels. It has now grown into an indispensable technology for oil and gas exploration and development, which leads to the evaluation of hydraulic fracturing effects,…
Recently developed optical inspection tools provide images from the inside of natural gas pipelines to monitor pipeline integrity. The vast amount of data generated prohibits human inspection of the resulting images. We designed an image processing…
Pipeline is one of the safest and most effective ways to transport oil and natural gas, whose quality is correlative with the safety of oil or gas transportation. Therefore, effective extractive detection of pipeline faults is essential. In the work…
