In order to assess hydraulics of LNAPLs in soil, the soil retention curves of petroleum and water were both determined through hanging column method. And, the hydraulic conductivity of petroleum and water were determined by steady head method. The water and petroleum hydraulic conductivities were 7.27 and 57.84 cm.day-1, respectively. The soil retention parameters were obtained based on van Gen...
Marine controlled source electromagnetic (MCSEM) surveys have become an important part of offshore petroleum exploration. In this paper we present a new approach to 3-D inversion of MCSEM data. It is based on rigorous integral equation (IE) forward modeling and a new IE representation of the sensitivity (Frechet derivative matrix) of observed data to variations in sea-bottom conductivity. This ...
Petroleum exploration and production is an industry that provides researchers with multi-variant challenging “real world” properties. Recently, some petroleum soft computing techniques have gained a greater interest in prediction within the oil industry. This paper is interested in the analysis, classifying, mining and predictions, based on fuzzy as an intelligent system and an intelligent syst...
The the Middle Cretaceous-Lower Miocene petroleum system of the Kupal oil field, located in the Dezful Embayment has been studied. The Kazhdumi and Pabdeh are main source rocks, the Sarvak, Ilam and Asmari formations are reservoir and the Gachsaran formation is the seal rock. According to geochemical analysis the Kazhdumi and Pabdeh contributed to oil production and feeding the Asmari and Bange...
enterprise resources planning (erp) systems are widespread software packages created to supply the information integrated development within various parts of organizations such as production, finance, and human resources. indeed, enterprise resources planning system is a software and hardware package by which organizations are able to manage the efficiency and effectiveness of using the resourc...
