Abstract: A drilling assembly in an elongated hole including a housing defining an interior with a plurality of motor stages in the interior. Each motor stage has at least one blade with supporting platform surfaces. A casing within the interior surrounds the plurality of motor stages and defines an annular flowpath with the housing.

Abstract: A tool is actuated in a well based on one or more issued commands being interpreted and implemented by the apparatus. The apparatus comprises a power generation module that multiplies pressure delivered downhole to enable actuation of the tool without requiring delivery of the higher actuation pressure along the entire wellbore. An actuation module may be used in combination with the power generation module to control operation of the power generation module in response to command signals sent downhole.
