This paper presents a feasibility study of evolutionary scheduling for gas pipeline operations. The problem is complex because of several constraints that must be taken into consideration during the optimization process. The objective of gas pipeline operations is to transfer sufficient gas from gas stations to consumers so as to satisfy customer demand with minimum costs. The scheduling involv...

Welcome to our international conference on rapid sea-level change. While concern about sea-level rise is global, our host country the Islamic Republic of Iran and the neighbouring Caspian countries have a concern of their own. Here, Caspian sea level rose a hundred times as fast as in the world’s oceans. Whereas oceanic sealevel rose 13 centimeter during the whole twentieth century, the Caspian...

Oil and gas pipelines are the infrastructure of national economic development. Deployment problem of wireless underground sensor networks (WUSN) for oil and gas pipeline systems is a fundamental problem. This paper firstly analyzed the wireless channel characteristics and energy consumption model in near-surface underground soil, and then studied the spatial structure of oil and gas pipelines a...

Kazakhstan has secured approval from Moscow to use its pipeline infrastructure in order transport 300,000 tons of oil Germany the first quarter 2023, a state-run company (Kaztransoil) announced on January 13, 2023. Deliveries January, 2023 amounted 20,000 tons. plans export up 1.5 million via Russia but future, volume could be increased 7 As for now, transportation through seems more beneficial...

Sir Humphry Davy witnessed the first chlorine hydrate crystallizing in 1811. Couple of century later his discovery, natural gas hydrates has begun to play an important role in energy business. From being a mere chemical curiosity, they have proven to be a nuisance for the natural gas industry. The problem of hydrate induced blockage in “wet gas” flow systems has been widely reported and became ...

Accident of oil and gas pipeline may result in enormous economic loss, great casualties and severe environmental pollution (Assael and Kakosimos, 2010). In the field of pipeline accident emergency, the Decision Support System (DSS) has been proposed to reduce the loss of an accident (Dey, 2001; Agbenowosi, 2000; Nataraj, 2005). However, their researches are mostly about risk management (Dey, 20...

Pipeline systems are vital infrastructure to national economy, and are widely used for transporting liquid and gas matter, such as oil, natural gas, water and chemic materials. However, effective and efficient management of pipeline systems are challenging, due to its mere lengths and the diverse deployment environments. Wireless sensor network (WSN) consists of a large number of sensors, which...

abstract the overall focus of the caspian sea security is shaped in four geopolitical areas contain the caucasus,(azerbaijan), central asia( turkmenistan and kazakhstan), russia,( ussr) a political unit in the international system which is one of the largest exporters of oil and gas in the north, and iran with huge reserves of oil and gas and oil industries in the south,. these important geopol...

Rockfall impact is one of the fatal hazards in pipeline transportation of oil and gas. The deformation of oil and gas pipeline caused by rockfall impact was investigated using the finite element method in this paper. Pipeline deformations under radial impact, longitudinal inclined impact, transverse inclined impact, and lateral eccentric impact of spherical and cube rockfalls were discussed, re...

Worldwide consumption in oil and natural gas is expected to lead all other energy sources in the next 20 years. The oil & gas pipeline network will constantly expand placing greater demand on operators to ensure any integrity threats to these pipeline systems are accurately and reliably identified. What are the main integrity threats to pipelines? There are many such as third-party damage, exte...
