Business solutions for a complex world Oil and gas capital projects series
in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
this paper presents an economic evaluation of gas to liquids (gtl) project using “south-pars” gas field of iran based on the latest actual performing gtl projects. iran has the world’s largest reserves of natural gas and can satisfy the projected long-term market demand of gtl products which have lower pollution and higher quality than refinery products. the results of cost-benefit analysis sho...
in this study, in order to consider the effects of cash flow fluctuations on project profitability, the new risk kind indicators are proposed to assess projects risk. firstly, project cash flow calculates on the basis of cost and revenue data in an lng project. then distribution curves of two variables, oil price and interest rate of foreign loans, are utilized to determine distribution curve o...
upstream oil and gas operations could have adverse impacts on the environment and society as well as the safety, security and health of people. therefore, as a pre-condition to commence any oil and gas project, there must be a comprehensive eshia report, prepared and submitted by contractor to doe, in which all necessary precautions and a concrete program are considered to avoid, control or red...
در حالت کلی معادلات حاکم بر یک مدل ریاضی از مخزن را نمی توان بوسیله روشهای تحلیلی حل کرد، در حالیکه یک مدل عددی می تواند بوسیله کامپیوتر جوابی تقریبی ارائه دهد. در این پایان نامه، یک دستگاه معادلات دیفرانسیل معمولی توسط گسسته-سازی معادله حاکم بر جریان شعاعی تک فازی نفت بسمت یک چاه (معادله چاه آزمایی) به دست آمده است. این سیستم شامل محاسبه تابع ماتریسی (exp(ka است که در آن k گام زمانی و a ماتریس...
A Service-Oriented Architecture for a Collaborative Engineering Environment in Petroleum Engineering
In this paper we discuss the scenario of Petroleum Engineering projects at Petrobras, a large Brazilian governmental oil & gas company. Based on this scenario, we propose a Service-Oriented Architecture (SOA) for a Collaborative Problem Solving Environment (CPSE), that we call Collaborative Engineering Environment (CEE), responsible for controlling and executing specialized engineering projects...
CO2 EOR and Storage in Oil Reservoirs — CO2 injection into tertiary oil reservoirs has been widely accepted as an effective technique for enhanced oil recovery (EOR), and has been used by the oil industry for over 40 years. Concerns over greenhouse gas emissions are leading to the investigation and realisation of its potential as a carbon storage method in recent years. With the right reservoir...
asphaltene instability is one of the major problems in gas injection projects throughout the world. numerous models have been developed to predict asphaltene precipitation; the scaling equation is an attractive tool because of its simplicity and not involving complex properties of asphaltene. in this work, a new scaling model is presented to account for asphaltene precipitation due to gas inje...
