0 | True Vertical Depth (TVD) in Reservoir EngineeringTrue Vertical Depth (TVD) is the vertical distance from a reference point (typically sea level) to a specific point within a reservoir, measured along a straight line perpendicular to the earth's surface. In reservoir engineering, TVD is crucial because it helps us:
Why not just use measured depth? While measured depth (MD) is the total length of a wellbore, it doesn't accurately reflect the vertical position of a point within the reservoir. This is because wells are rarely drilled vertically. They often follow a deviated path to reach target formations, which means MD doesn't accurately reflect the actual vertical distance to the reservoir. Key points about TVD:
In essence, TVD provides a more accurate representation of the true vertical distance within a reservoir, offering essential insights for understanding and managing the reservoir's characteristics. answer Aug. 4, 2024, 12:05 p.m. valdout39 0 0 0 gold badges 0 0 silver badges 0 0 {% trans "bronze badges" } |
