Wellbore Stability in Shale Formation Using Analytical and Numerical Simulation
Optimization of drilling fluid parameters such as mud weight, salt concentration, and temperature is essential to alleviate instability problems during drilling through shale sections. The selection of suitable mud parameters can benefit from analyses that consider significant instability processes involved in shale-drilling–fluid interactions. This paper describes the development of analytical...

امروزه تصحیح همکلاسی در کلاسهای نگارش یکی از اجزاء لاینفک کلاسهای دانش آموز محور است. تاثیرات مفید تصحیح همکلاسی بر زبان آموزان، معلمان را متقاعد کرده است که علیرغم صرف زمان، انرژی و توان بسیار، از این شیوه ی آموزشی در کلاسهای آموزش نگارش بهره بگیرند. تحقیق حاضر بر آن است تا با مقایسه دو گروه از یادگیرندگان زبان انگلیسی، تاثیر تصحیح همکلاسی را بر توانایی نوشتاری آنها نشان دهد. 122 خانم زبان آمو...
15 صفحه اولStudy on Wellbore Stability and Instability Mechanism in Piedmont Structures
Piedmont tectonic belts are rich of oil and gas resources, however the intense tectonic stress and broken formation may cause great drilling problems in piedmont structures such as borehole collapse, lost circulation and gas cutting. Through analysis of in situ stress properties, bedding structure and mechanical characteristics, wellbore instability mechanism was expounded from rock mechanics, ...
متن کامل2D Numerical Simulation of Improving Wellbore Stability in Shale Using Nanoparticles Based Drilling Fluid
The past decade has seen increased focus on nanoparticle (NP) based drilling fluid to promote wellbore stability in shales. With the plugging of NP into shale pores, the fluid pressure transmission can be retarded and wellbore stability can be improved. For better understanding of the interaction between shale and NP based drilling fluid based on previous pressure transmission tests (PTTs) on A...
