DrillingForGas - Well Control - Deviated and ...

2021-11-13  2. Kick control in horizontal wells. In principle, well control calculations for deviated wells also apply for horizontal wells. However, a bottom hole angle of 90 degrees for the horizontal section cannot be used in the calculations, because of practical arithmetical reasons. An assumed bottom hole angle of 89 degrees should be used instead.

Search: Sand control in horizontal and deviated wells SPE

Abstract The gravel packing process in horizontal or highly deviated wells involves the solid-liquid two-phase flow and the sand-bed migration under complicated conditions, in which the sand carrier fluid filtrates into the formation and the mass exchange occurs between the fluid in screen-washpipe annulus and the fluid in casing-screen annulus.

Abstract. Many problems in drilling highly deviated wells can be related to the drilling mud. Poor hole cleaning, excessive torque, drag and hole fill, stuck pipe, well bore instability, loss of circulation, formation damage, poor cement jobs, and difficulties running wireline logs are among the problems that can result if a mud job is executed poorly.
