The oil and gas industry will continue to boom in the coming future. Obtaining oil and gas from conventional and non-conventional resources will become more and more challenging. This intensifying need will impose very considerable demands on work force, financial and technology capabilities. Since the future supplies of oil and gas are to expand, advanced technology will become increasingly ne...

Because of the continuous growth of electric energy consumption and the trend with electric lines of high voltages energy transport and metal pipelines which compose the transport of the fluids and liquid or gas hydrocarbons in the same corridor, the parallelism and the proximity of the power lines and the metallic pipelines become increasingly common. Consequently, it was an increasing concern...

n this essay, we present design and simulation of a Leakage detection and alocation of oil pipelines system using sensing the temperature distribution of optical fiber by COMSOL Multiphysics software. In this system, telecommunication single-mode optical fiber, 200 m typical length is used, in 1.55 μm electromagnetic wave. The proposed system, uses of Brillouin frequency shift occurred on fiber...

Real-time models and associated applications have been widely used to support the safe and effi cient operation of pipelines from within the confi nes of the pipeline operations environment. Commercial systems have also been independently implemented to manage the business relationships between gas suppliers, shippers, transporters, and end users; however, the direct interchange of information ...

In order to develop a Failure Analysis Expert System (FAES), with application for onshore pipeline transporting oil and gas products, the work was split in two parts. Previously failure database and knowledge acquisition method were described in the first part whereas the present, part II, the End-User interface and Algorithm are explained in detail. The proposed Failure Analysis Expert System ...

An excess Gibbs free energy model is applied to in®estigate the influence of n-paraffin composition on the aging beha®ior of wax-oil gel deposits known to form in subsea petroleum transport pipelines. The aging of wax-oil gels occurs by a counterdiffusion process where wax molecules with carbon numbers greater than a critical carbon num( ) ber CCN diffuse into the gel matrix, and ®ice ®ersa. Mo...

We investigate the pricing formation of natural gas markets on three different continents (Europe, Asia and North America). We find that natural gas markets showed a strong relationship with the crude oil market between 1992 and 2001 and natural gas prices tended to thermal parity with crude oil prices. From 2002 natural gas markets exhibited a less pronounced relationship with the crude oil ma...

Girth weld defects in long-distance oil and gas pipelines are one of the main causes pipeline leakage failure serious accidents. Magnetic flux (MFL) is most widely used inline inspection methods for pipelines. However, it impossible to determine type girth defect via traditional manual analysis due complexity MFL signal. Therefore, an automatic image classification method based on deep convolut...
