Abstract The foraminiferal contents of the lower–middle Miocene succession exposed in three sections north Nur Abad on northwestern side High Zagros Thrust Belt were studied. Assemblages larger foraminifera from these can be referred to Zone SBZ 25 (and Miogypsina globulus and intermedia subzones), which correlates with Burdigalian Stage. For first time, planktonic documented area document Lang...

The escalation of oil prices in the last years has motivated a debate about natural resources taxation. This paper uses real options approach to discuss different taxation devices for exploration & production (E&P) with focus in Brazilian petroleum sector. The concept of tax neutrality under uncertainty is established when both the project value and investment follows correlated stochastic proc...

Decision making pertaining to injection profiles during oilfield development is one of the most important factors that affect the oilfields’ performance. Since injection profiles are affected by multiple geological and development factors, it is difficult to model their complicated, non-linear relationships using conventional approaches. In this paper, two adaptivenetwork-based fuzzy inference ...

In today’s society, with the continuous growth of energy demand, Bohai Oilfield, as an important offshore oil resource base in China, is facing increasingly severe challenges while contributing to national security. order improve quality water injection oilfield and gradually achieve efficient stable production, Oilfield has launched a well pressure optimization project, focusing on improving e...

Oilfield underground fracturing technology is an important oilfield development technology, through the injection of fluid to make rock fracture expansion, in order improve productivity oil reservoir. In this paper, selection and design fluid, tools devices, control parameters, evaluation fractures, adjustment optimization after are discussed. Through analysis these points, it can provide guida...

This paper explores the use of intranet-technology to support knowledge intensive decisionmaking in a technical service delivery process of a major oilfield services company. Our findings show that creating, mobilizing, and exchanging knowledge through an intranet-technology based system delivers forms of benefits to both the organization and its clients, and understanding what organizational k...

In the Cheshmeh-Bid district of Khajeh-Jamali ophiolitic massifs (Southern Iran), mantle peridotites are intruded by abundant pyroxenite dykes. A few these dykes remarkable for occurrence native copper associated with development a metasomatic reaction zone. The progressively reacted, from their margins towards center, an amphibole + antigorite selvage, followed centimeter-thick clinopyroxene a...

Bohai A Oilfield is the first fluvial facies oilfield in Sea to be developed using a horizontal well layering system. It has characteristics of thin single sand reservoir thickness, large differences reserve scale, rapid lateral changes reservoirs, and staggered stacking multiple river channel bodies vertical direction. In production, it characterized by decline ground pressure, increase water ...
