Pressure in the deep-water pipeline is an important parameter that should be carefully predicted to control natural gas transport petroleum industry. However present methods predict pressure along are complex and time-consuming. Some even ignore formation of hydrate leading inaccurate prediction. In this work, we proposed a model considering reduction radius induced by hydrate. The was validate...

offshore pipelines used for oil and gas transportation are often buried to avoid damage from fishing activities and to provide thermal insulation. thermal expansion and contraction of the pipeline during operation can lead to lateral or upheaval buckling. a safe buried pipeline design must take into account a reliable evaluation of soil uplift resistance and pipe embedment depth. while the cost...

using natural gas as a clean, plentiful and inexpensive source of energy in recent years has progressively increased in iran. pipelines are the most common system to transport natural gas from field to different regions of iran. these pipelines always pose risks to surrounding population and environments. the aim of this study was to assess the potential health, safety, and environment risk of ...

The temperature field evolving in the limestone around the district heating tunnel in Copenhagen due to operation of the long-distance heating pipelines is investigated by means of poro-hydro-thermal numerical analyses. The presented parametric studies illustrate the coupling between the temperature and the groundwater flow. It is shown how a general horizontal groundwater flow and the hydrauli...

This study aims to predict leaks in water-carrying pipelines by monitoring pressure drops. Timely detection of is crucial for prompt intervention and repair efforts. In this research, we represent the network structure using graph representations. Consequently, propose a machine learning model called Graph Convolutional Neural Network (GCN) that leverages graph-type data structures leak predict...

The Water Resources Authority of Jamaica (WRAJ) under the instruction of the Ministry of Water, Jamaica is the organization responsible for water resource management on the island of Jamaica. The management of these ground-water basins involves transmitting and storing varying portions of the area’s water supply by coordinating aquifer functions with surface facilities, e.g. reservoirs and pipe...

This paper is the first of a series that attempts to assess the possible health and safety risks associated with large scale CO2 sequestration in deep brine reservoirs. The approach is based on analysis of available data on the operational track record from CO2 transportation and injection associated with enhanced oil recovery (CO2-EOR) in the US. This paper is particularly concerned with ident...

This paper presents research results within real-time production optimization and reservoir management at the Center for Integrated Operations in the Petroleum Industry (IO center). This includes life-cycle and long term issues like well location and target production rates. Further, results on short term production optimization, for instance the allocation of target production between wells an...

Kathmandu valley is believed to be a lake in pre-historic period. But later, it became suitable for human settlement and the civilization started in Kathmandu. With increase in population, the available water becomes insufficient and people started to search new sources by constructing well and stone spout. With time as the city grew, people faced the shortage of water. The river water was dete...
