Abstract
An universal bottom hole orienting sub (UBHO) and fishing tool & technique are designed for the retrievable probe type MWD tool which used to during oil & gas wells. The mean features of the new UBHO are to eliminate the axial shocks affecting MWD tool's performance while drilling operations and cause the major MWD tool failures. Secondly, it adapted a tight support for MWD tool into drill string with fully capability to retrieve & replace MWD tool down hole, especially in the horizontal section, result in reliable & correct transmitted data. The "Mud pushing block" fishing tool & technique using wire line fishing operations implementing the capability to fish and replace MWD tool down hole at any hole inclination, even in the horizontal section "until now the MWD tool fishing operations are limited to certain hole inclination" which lead to increase MWD's marketing value. Main while this fishing tool &
technique could be used in wide range in the other wire line through tubing & drill string operations.

Description
An universal bo hole orienting sub (UBHO) and fishing tool & technique are designed for the retrievable probe type MWD too 'ch used to during oil & gas wells. The mean features of the new UBHO are to eliminate the axial shocks a ting MWD tool's performance while drilling operations and cause the major MWD tool failures. Secondly, it ted a tight support for MWD tool into drill string with fully capability to retrieve & replace MWD tool down ho (;specially in the horizontal section, result in reliable & correct transmitted data. The "Mud pushing block' ing tool & technique using wire line fishing operations implementing the capability to fish and replace tool down hole at any hole inclination, even in the horizontal section "until now the MWD tool fishing op dons are limited to certain hole inclination" which lead to increase MWD's marketing value. Main while this r ' g tool & technique could be used in wide range in the other wire line through tubing & drill string operatio Specification -Invention overview:
A universal bottom hole orienting sub (UBHO) and fishing tool & technique involved with eliminate the axial shocks affecting retrievable probe type MfVD tool. UBHO tool is designed to prevent MWD tool from jumping or turning while drilling operations, especially throughout the well horizontal section, result in guaranteed a correct transmitted data. The fishing tool implementing the possibility to fish MWD tool at any hole inclination angle even throughout horizontal section.
The disadvantage of present I1BH0 and fishine technigue used for retrievable probe type MWD tool:
-Axial shocks results in drilling environments;
This kind of shocks existing while steering; & rotary drilling modes, due to drilling impacts in addition to motor vibrations.
-MWD tool jumping from UBHO key seat.;
Due to the supporting of MWD tool into UBHO key seat only by tool weight, it can jump easily causing either turning tool face and misleading MV~JD engineer result in non correct well path or while directional driller trying to jerk drill string while steering. Also MWD tool jump when turn rig pumps off.
-MWD tool hi side tool face turning;
In some cases the key sleeve bolts screw out UBHO or become loose due to down hole temperature and vibrations. The key sleeve will turn right or lift causing misleading MWD's hi side result in non-correct well path.
-MWD tool retrieve ability limitation;
Until date the retrieve ability of probe type MWD tool is limited to certain degree of hole inclination using slick line fishing operations.

Applicant: Hamdy Hassan Mohamed, HUSSEIN
The advantages of new UBHO anti fishing tool & technipue used for retrievable probe type MWD tool:
-Axial shocks elimination features;
UBHO design adapting MWD tool to bounce up and down in between two spring cushion lead to safe MWD
tool from drilling axial shocks which resulting in long tool life down hole and cut spare parts costs.
-Correct tool face always guaranteed features;
UBHO adapted to support MWD tool by latching mechanism which make MWD tool always in the same position down hole with fully capability to fish & replace MWD tool down hole.
-Fishing features;
'The "mud pushing block" fishing tool adapted especially for wire line fishing operations at any hole inclination using mud pumping force, even in the horizontal section.
