PTFE Application in Oilfield Development

Semantic Exploitation of Engineering Models: An Application to Oilfield Models

Engineering development activities rely on computer-based models, which enclose technical data issued from different sources. In this heterogeneous context, retrieving, re-using and merging information is a challenge. We propose to annotate engineering models with concepts of domain ontologies, which provide data with explicit semantics. The semantic annotation makes it possible to formulate qu...

Offshore Oilfield Development Planning under Uncertainty and Fiscal Considerations

The objective of this paper is to present a unified modeling framework to address the issues of uncertainty and complex fiscal rules in the development planning of offshore oil and gas fields which involve critical investment and operational decisions. In particular, the paper emphasizes the need to have as a basis an efficient deterministic model that can account for various alternatives in th...

development of feminist poetics in adrienne rich

اشعار ریچ، به عنوان اشعاری که همیشه در حال تغییر و دگرگونی هستند، تجسمی از رشد و دگرگونیِ انسان هستد. پایان نامه ی حاضر، با تمرکز بر روی مراحل سیر شعری ریچ از تغییری در دنیا به عکس هایی فوری از یک عروس، سپس به شیرجه به درون کشتی شکسته و در نهایت به صبری عجیب مرا تا اینجا آورده، به بررسی این مراحل در قالب نظر شوالتر در رابطه با سه مرحله ی پیشرفت ادبی زنان یعنی مرحله ی زنانه، زن گرا و زن محور می پ...

Modification of PTFE nanopowder by controlled electron beam irradiation: A useful approach for the development of PTFE coupled EPDM compounds

Low-temperature reactive mixing of controlled electron beam modified Polytetrafluoroethylene (PTFE) nanopowder with Ethylene-Propylene-Diene-Monomer (EPDM) rubber produced PTFE coupled EPDM rubber compounds with desired physical properties. The radiation-induced chemical alterations in PTFE nanopowder, determined by electron spin resonance (ESR) and Fourier transform infrared (FTIR) spectroscop...
