... The objective of this study is to use an elastic analytical approach for modeling the stress field for wells of different inclination angles in various stress regimes, and for common lithologies. The linear-elastic analysis is perhaps the most common approach due to its ease of application...

... with increased pipe ID in the downstream section. Test data were analyzed by calculating slug frequency and slug length ratio as a slug development/dissipation index. Presented in this report are experimental results that illustrated sensitivity of slug dissipation to inclination angles and down-stream pipe ID...

... of the wellbore, and the y′ axis is oriented to the high side of the hole. The tool face angle is measured clockwise from the y′ axis in the x′y′ plane of the traveling coordinate system. If the inclination angle is zero, the y′ axis is arbitrarily oriented due north such that the tool face angle is equal...
