Deviated flow
Webn. [Reservoir Characterization] The angle at which a wellbore diverges from vertical. Wells can deviate from vertical because of the dips in the beds being drilled through. Wells can also be deliberately deviated by the use of a whipstock or other steering mechanism. Wells are often deviated or turned to a horizontal direction to increase ... WebIn future, a calculation software of flow friction and pressure in deviated / horizontal well will be programmed, which provides an accurate method for hydraulic
