ABSTRACT:
In an aspect, a drill bit is provided that includes at least one blade profile having a side section and an adjustable pad on the side section that is configured to extend from the side section to cause the drill bit to alter a drilling direction when the drill bit is used to drill a wellbore. In addition, the drill bit may also include a fluid line configured to supply a fluid under pressure to the pad to cause the pad to extend from the side section.
