Multidirectional wellbore penetration system and methods of use

Abstract

A drilling assembly includes a hydraulic jet disposed on a downhole end of a fluid line, and one or more adjustable jet nozzles on the hydraulic jet in multiple angular orientations relative to a central axis of the hydraulic jet. The one or more adjustable jet nozzles provide fluid pressure to penetrate a formation and cut multiple angular channels.

What is claimed is: 
     
         1 . A drilling assembly comprising:
 a hydraulic jet disposed on a downhole end of a fluid line; and   one or more adjustable jet nozzles on the hydraulic jet in multiple angular orientations relative to a central axis of the hydraulic jet,   wherein the one or more adjustable jet nozzles provide fluid pressure to penetrate a formation and cut multiple angular channels.   
     
     
         2 . The bottomhole assembly of  claim 1 , further comprising one or more hydraulic centralizers disposed along a length of the flexible line to centralize the hydraulic jet. 
     
     
         3 . The bottomhole assembly of  claim 2 , wherein the one or more hydraulic centralizers includes a plurality of circumferential radial jet nozzles to provide a circumferential jet stream radially outward. 
     
     
         4 . The bottomhole assembly of  claim 3 , wherein the radial jet nozzles are evenly spaced about a circumference of the hydraulic centralizers. 
     
     
         5 . The bottomhole assembly of  claim 3 , wherein the radial jet nozzles are unevenly spaced about a circumference of the hydraulic centralizers. 
     
     
         6 . The bottomhole assembly of  claim 1 , wherein the one or more jet nozzles are configured having various diameters. 
     
     
         7 . The bottomhole assembly of  claim 1 , wherein a jet size of the one or more jet nozzles is adjustable downhole. 
     
     
         8 . A cutting device comprising:
 a cutter disposed on an end thereof;   a spacer section proximate to the cutter; and   a guide channel having a radius of curvature,   wherein a length of the spacer and bearing section corresponds with the guide channel radius of curvature to create a particular cutter path angle through a casing wall.   
     
     
         9 . The bottomhole assembly of  claim 8 , wherein the guide channel has a radius of curvature to provide an exit angle therefrom of between about 5 degrees and 90 degrees relative to a central axis of the cutting device. 
     
     
         10 . The casing cutting device of  claim 8 , wherein the spacer section comprises at least two bearing sleeves located axially on each end of the spacer section. 
     
     
         11 . The bottomhole assembly of  claim 10 , wherein the at least two bearing sleeves are non-rotating. 
     
     
         12 . The bottomhole assembly of  claim 8 , wherein the guide channel is within a guide body de-centered within a wellbore. 
     
     
         13 . The bottomhole assembly of  claim 8 , wherein the cutter comprises a bull nose type high speed steel or tungsten cutter. 
     
     
         14 . A method of drilling a formation, the method comprising:
 inserting, into a formation channel, a hydraulic jet comprising one or more multi-directional jet nozzles;   providing high pressure fluid through the multi-directional jet nozzles; and   cutting one or more multi-angle lateral channels through the formation.   
     
     
         15 . The method of  claim 14 , further comprising:
 traversing a cutter along a guide channel having a radius of curvature, providing a spacer section proximate to the cutter, wherein the spacer section has a length that corresponds with the radius of curvature of the guide channel; and   cutting one or more holes through a wellbore casing.   
     
     
         16 . The method of  claim 15 , further comprising running the cutter and the hydraulic jet into the wellbore casing in a single trip. 
     
     
         17 . The method of  claim 15 , further comprising de-centering the guide channel within the wellbore casing with a plurality of spring-loaded locking pads. 
     
     
         18 . The method of  claim 14 , further comprising centralizing the hydraulic jet in the formation channel with a circumferential jet stream from one or more hydraulic centralizers. 
     
     
         19 . The method of  claim 14 , further comprising orienting the one or more multi-directional jet nozzles in one or more angular directions. 
     
     
         20 . The method of  claim 14 , further comprising adjusting a size of the one or more jet nozzles.
