Abstract

Deepwater extended hardrock completion systems comprising a wellbore penetrating a subsea subterranean formation, wherein the wellbore comprise a near vertical first portion, a deviated second portion, and a deviated third portion.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A deepwater extended hardrock completion system comprising a wellbore penetrating a subsea subterranean formation, wherein the wellbore comprise a near vertical first portion, a deviated second portion, and a deviated third portion. 
     
     
         2 . The deepwater extended hardrock completion system of  claim 1 , wherein a portion of the wellbore comprises an open-hole wellbore. 
     
     
         3 . The deepwater extended hardrock completion system of  claim 1 , wherein the near vertical first portion is deviated from vertical at an angle in the range of from 0° to 20°. 
     
     
         4 . The deepwater extended hardrock completion system of  claim 1 , wherein the deviated second portion is deviated from vertical at an angle in the range of from 30° to 90°. 
     
     
         5 . The deepwater extended hardrock completion system of  claim 1 , wherein the deviated third portion is deviated from vertical at an angle in the range of from 30° to 45°. 
     
     
         6 . The deepwater extended hardrock completion system of  claim 1 , wherein the deepwater extended hardrock completion system further comprises a lower completion string disposed within the wellbore. 
     
     
         7 . The deepwater extended hardrock completion system of  claim 1 , wherein the lower completion string has a modular design. 
     
     
         8 . The deepwater extended hardrock completion system of  claim 1 , wherein the lower completion string comprises one or more open hole packers, one or more frac sleeves, and one or more production sleeves. 
     
     
         9 . The deepwater extended hardrock completion system of  claim 8 , wherein the one or more frac sleeves comprise bores with inner diameters in the range of from 3 inches to 6 inches. 
     
     
         10 . The deepwater extended hardrock completion system of  claim 8 , wherein the one or more frac sleeves comprise multidirectional hydra jetting nozzles.
