Abstract:
Methods for installing tubulars into a highly deviated wellbore may include a) drilling the well to the planned total depth of the interval, b) placing a first fluid into the wellbore below a prescribed measured depth in the high-angle portion of the wellbore, c) placing a second fluid into the wellbore above the prescribed measured depth, d) plugging the distal port ion of the tubular with a lower plug and an upper plug, e) as the tubular is run into the wellbore, placing a lightweight fluid into the plugged section of tubular and a heavy fluid above the plugged section of tubular, and f) running the tubular into the wellbore to the planned total depth. The first fluid has a density that causes the portion of the tubular that extends into the first fluid to become substantially neutrally buoyant, and the second fluid has a density less than the first fluid.
