Effects of the Produced Water from a Sour Oilfield in South Kuwait on the Production Tubing

引用

Journal of Water Resource and Protection 2023年第7期15卷 358-375页

作者： Feras Al Salem Vijo Poulose Kazuyuki kawamura Arata Nakamura Hakim Saibi Thies Thiemann Department of Biology College of Science United Arab Emirates University Al Ain United Arab Emirates Department of Chemistry College of Science United Arab Emirates University Al Ain United Arab Emirates Technology and Research Center Japan Organization for Metals and Energy Security (JOGMEC) Chiba Japan Department of Geosciences College of Science United Arab Emirates University Al Ain United Arab Emirates

Kuwaiti oil production faces a growing challenge in the increasing quantities of produced water generated in the production of oil. The high water cut of the produced fluid from the wells and the high salinity of the produced water lead to significant degradation of subsurface equipment, specifically the production tubing. Debris generated through the degradation of the inner part of the tubing becomes a constituent of the scaling that deposits in the tubing and blocks the flow of the production fluid, inducing higher maintenance costs. This paper looks at the characteristics of the scaling in regard to the produced water and outlines the economic impact of the produced water induced degradation of the tubing structure.

Measuring and evaluating of road roughness conditions with a compact road profiler and ArcGIS

Journal of Traffic and Transportation Engineering(English Edition) 2016年第5期3卷 398-411页

作者： Nueraihemaitijiang Abulizi Akira kawamura Kazuya Tomiyama Shun Fujita Graduate School of Engineering Kitami Institute of TechnologyHokkaido 090-8507Japan Department of Civil and Environmental Engineering Kitami Institute of TechnologyHokkaido 090-8507Japan Hokkaido Regional Development Bureau Ministry of LandInfrastructureTransport and TourismHokkaido 090-8507Japan

With a wide range of requirements throughout the world, high-quality road management is subject to increasing demand from a perspective of customer-oriented levels of service. In recent years, road administrators are requested to create a visual map of a road network to monitor conditions. To fulfill these requirements, this study conducted as follows. Firstly, this paper introduces a new compact road profiler to collect the profile data at ease. Using the international roughness index （IRI） to assess public roads in local cities of Japan＇s Hokkaido prefecture, this study also provides real-time monitoring of pavement roughness conditions. Moreover, this study deals with an effective method for visualizing collected IRI data as an attribute in a geographic information system （GIS） and the database of Japan digital road map （DRM）. Secondly, the authors present the measurement results of IRI at two different cities during different seasons by using GIS to compare the road conditions. According to the results clarified on different statistical characteristics of road profiles, this study recommends that it is necessary to establish pavement management system （PMS） in consideration of road class, network of local city, and evaluation and management of road conditions in winter quantitatively. Finally, the authors measure and evaluate ride quality by assessing differences between the inner wheel path （IWP） and outer wheel path （OWP） of the vehicle into account, using the previously mentioned profilers and the driving simulator, which is called KITDS. Results show that information from both wheel paths contributes to improve current monitoring process regarding pavement surface, and expects to construct a high level of PMS for road administration in the future.
