1. A system for use in a well, comprising:
a well tool;
a centralizer system configured to adjust a lateral position of the well tool in a borehole of the well, the centralizer system comprising:
a plurality of extensions extending outwardly from the well tool, wherein the plurality of extensions comprise a first set of extensions and a second set of extensions separated by a longitudinal distance along a length of the well tool;
a plurality of hydraulic pistons coupled with the plurality of extensions, wherein each of the plurality of hydraulic pistons is configured to enable individual control of an extension position of a corresponding extension of the plurality of extensions, and wherein each of the plurality of hydraulic pistons is configured to move coaxially with the corresponding extension; and
a valve system controllable to meter hydraulic fluid to the plurality of hydraulic pistons such that a position of the well tool in the borehole is controlled via the plurality of extensions.
