Abstract: A tool string disposed in at least one tubular having upper and lower threaded connections to connect to a drill string. The tool string includes a shock reduction tool, which includes an anchoring tail piece axially and rotationally fixed to the at least one tubular. A universal bore hole orientation (UBHO) muleshoe sub is disposed at an upper end of the shock reduction tool. A downhole electronics package coupled to the UBHO muleshoe sub.

Abstract: A shock reduction tool includes an upper interconnect module configured to electrically and mechanically orient and connect to an upper module and a lower interconnect module configured to electrically and mechanically orient and connect to a lower module. A shock absorber section is disposed between the upper interconnect module and the lower interconnect module. A wire management section is disposed between the upper interconnect module and the lower interconnect module. A plurality of wires electrically connect the upper interconnect module and the lower interconnect module and pass through the shock absorber section and the wire management section.

Abstract: A hydraulic shock absorbing method for protecting the drill bit and drill pipe in rotary earth drilling comprising the steps of slidably moving an anvil connected to a drilling bit in a casing in response to increased down weight on the drill bit and sequentially transmitting further increases in the down weight and shocks from the anvil to a plurality of independently operating hydraulic pistons slidably mounted within the casing when down weight on the drill bit exceeds increasing predetermined amounts to activate the pistons in sequence. The drilling fluid within the casing is transmitted to first pressure areas on the anvil and the plurality of pistons and the drilling fluid is passed through the drilling bit to provide a pressure drop and then communicated to second pressure areas on the plurality of pistons.
