A segment of natural gas pipeline was damaged due to landsliding near Hendek. Re-routing of the pipeline is planned, but it requires the preparation of a landslide susceptibility map. In this study, the statistical index (Wi) and weighting factor (Wf) methods have been used with GIS to prepare a landslide susceptibility map of the problematic segment of the pipeline. For this purpose, thematic layers including landslide inventory, lithology, slope, aspect, elevation, land use/land cover, distance to stream, and drainage density were used. In the study area, landslides occur in the unconsolidated to semi-consolidated clayey unit and regolith. The Wf method gives better results than the Wi method. Lithology is found to be the most important aspect in the study area. Based on the findings obtained in this study, the unconsolidated to semi-consolidated clayey unit and alluvium should be avoided during re-routing. Agricultural activities should not be allowed in the close vicinity of the pipeline.

Numerical analysis and stability assessment of complex secondary toppling failures: A case study for the south pars special zone Azarafza, Mohammad; Bonab, Masoud Hajialilue; Akgün, Haluk (2021-12-01) This article assesses and estimates the progressive failure mechanism of complex pit-rest secondary toppling of slopes that are located within the vicinity of the Gas Flare Site of Refinery No. 4 in South Pars Special Zone (SPSZ), southwest Iran. The finite element numerical procedure based on the Shear Strength Reduction (SSR) technique has been employed for the stability analysis. In this regard, several step modelling stages that were conducted to evaluate the slope stability status revealed that the mai...
Mathematical Modelling of Wax Deposition in Crude Oil Pipeline Systems Kök, Mustafa Verşan; Saracoglu, Onder (2000-01-01) Deposition of wax on the wall of the crude oil pipelines is regarded as a problem since the pipeline diameter is reduced. Therefore more power is required to force the same amount of crude oil through the system. In this study, a mathematical model is developed for estimation of wax deposition in crude oil pipeline systems. A computer program was developed to simulate wax deposition phenomena. Each component is characterized by weight fraction, heat of fusion and melting point temperature. Temperature profi...
Optimum matrix acidizing: How much does it impact the productivity Al Rbeawi, S.; Kadhim, F. S.; Farman, G. M. (2018-08-09) Formation damage is one of the big challenges for oil and gas oilfields development. Several types of formation damage most likely exist during the entire life of producing wells. Formation damage can occur during the drilling or coring operations, well completion, work-over and production. The most important problems that affect formation during drilling operations are mud filtrate and fines invasion. There are different damage mechanisms affect reservoirs for instance pore blocking by solids, clay swellin...
GIS-based structural performance Assessment of Sakarya City after 1999 Kocaeli-Turkey earthquake from geotechnical and earthquake engineering point of view Yılmaz, Zeynep; Çetin, Kemal Önder; Department of Civil Engineering (2004) The August 17, 1999 Kocaeli-Turkey Earthquake (Mw=7.4) caused severe damage to the structures and lifelines in the Marmara region. Soil liquefaction was identified as one of the major causes of this damage. The aim of this study is to determine geotechnical and earthquake engineering factors that contribute to the structural damage observed in Sakarya city after 1999 Kocaeli Earthquake. For this purpose, the results of an extensive field investigation program compiled by General Directorate of Disaster Affa...
Hierarchical approach to semi-distributed hydrological model calibration Özdemir, Ayfer; Leloğlu, Uğur Murat; Abbaspour, Karim; Department of Geodetic and Geographical Information Technologies (2016) In recent years, water resources were negatively affected from uncontrolled agricultural, industrial activities and settlements on river basins. Hydrologists and water resource managers have widely used hydrologic models as tools for water resources development, water environment preservation, water resources allocation and understanding utilization. In order to apply hydrological models successfully in practical water resources investigations, careful calibration and uncertainty analysis are needed. Hydrol...
