摘要：
In one aspect, a method of determining a corrected weight-on-bit is provided, which method, in one embodiment, may include: drilling a wellbore with the drill bit; determining a weight-on-bit while drilling the wellbore; determining a pressure differential across an effective area of the drill bit while drilling the wellbore; and determining the corrected weight-on-bit from the determined weight-on-bit and the determined pressure differential.
