This study deals with onshore oilfield drilling fluid system to drill corrosion. Corrosion under static and dynamic conditions of the drilling fluid was evaluated. The effect of temperature and pressure on corrosion was examined. Corrosion was more severely affected by temperature compared to pressure. The combined effect of a deoxidizing agent and an inhibitor was observed to exhibit better pr...

knowledge of the orientation of horizontal in situ stresses is important to some areas of oil and gas field development plans. borehole breakouts observed in image logs and drilling-induced fractures are the main parameters for the determination of the stresses’ directions in situ. in this work, the orientations of borehole breakouts were investigated as a function of depth in oil wells a and b...

Since 2006 wastewater has been injected below the Val d'Agri Quaternary basin, the largest on-land oilfield in Europe, inducing micro-seismicity in the proximity of a high-rate injection well. In this study, we have the rare opportunity to revise a massive set of 2D/3D seismic and deep borehole data in order to investigate the relationship between the active faults that bound the basin and the ...

A Oilfield is Fluvial Facies Low Permeable Reservoir, main layer bend distributary channel sand body deposition, In order to better understand the distribution of single and remaining oil in reservoir, inspection well coring tracer tests have been carried out successively same area oilfield, based on these data, it found that, actual very different from original description both vertical plane....

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...
