Integrated Snubbing Operating Platform

Abstract

An integrated snubbing platform is provided that includes a snubbing section including a snubbing jack assembly and a secondary blowout preventer (BOP) connected to the snubbing jack assembly; and a primary BOP section connected directly to the secondary BOP. The integrated snubbing platform is transportable as a single unit and mountable onto a wellhead as a single unit. A method of mounting a snubbing assembly, a secondary BOP unit and a primary BOP stack onto a wellhead is also provided. The method involves first providing an integrated snubbing platform having a snubbing section that includes a snubbing jack assembly and a secondary blowout preventer (BOP) connected to the snubbing jack assembly; and a primary BOP section connected directly to the secondary BOP. The method then involves mounting the integrated snubbing platform onto a wellhead as a single unit.

1 . An integrated snubbing platform comprising:
 a. a snubbing section comprising:
 i. a snubbing jack assembly; and 
 ii. a secondary blowout preventer (BOP) connected to the snubbing jack assembly; and 
   b. a primary BOP section connected directly to the secondary BOP;   wherein the integrated snubbing platform is transportable as a single unit and mountable onto a wellhead as a single unit.   
     
     
         2 . The integrated snubbing platform of  claim 1 , wherein the integrated snubbing platform is mountable onto a wellhead by opening only one sealing gasket. 
     
     
         3 . The integrated snubbing platform of  claim 1  wherein the snubbing section comprises a jackplate housing one or more traveling slips, a hydraulic assembly, one or more stationary slips, an annual BOP and a single stripping BOP. 
     
     
         4 . The integrated snubbing platform of  claim 1 , wherein the snubbing section comprises one or more traveling slips, one or more stationary slips, an annual BOP and an equalizer spool, said equalizer spool comprising one or more ports for allowing for bleed off and pressure equalization of the snubbing section. 
     
     
         5 . The integrated snubbing platform of  claim 3 , wherein the stripping BOP comprises hardened rubber interior components. 
     
     
         6 . The integrated snubbing platform of  claim 3 , wherein the stripping BOP comprises Teflon interior components. 
     
     
         7 . The integrated snubbing platform of  claim 1 , wherein the primary BOP stack section comprises one or more double BOP's and a further equalizer spool. 
     
     
         8 . The integrated snubbing platform of  claim 7 , wherein the primary BOP stack section further comprises an annular BOP above the double BOP. 
     
     
         9 . The integrated snubbing platform of  claim 3 , wherein the hydraulic assembly comprises one or more hydraulic jack cylinders that extend a full length of both the snubbing and primary BOP sections of the platform. 
     
     
         10 . The integrated snubbing platform of  claim 9 , wherein the hydraulic jack cylinders are anchored and supported from an upper crosshead located between the stationary slips and the annual BOP of the snubbing section. 
     
     
         11 . The integrated snubbing platform of  claim 10 , wherein the hydraulic jack cylinders are accommodated through a mid-ship plate located between the snubbing section and the primary BOP section, so as to be floatable through the mid-ship plate. 
     
     
         12 . The integrated snubbing operating platform of  claim 1 , wherein snubbing section and primary BOP section are powerable by a central hydraulics system. 
     
     
         13 . The integrated snubbing operating platform of  claim 12 , wherein the integrated snubbing platform can be operated by a remote control panel operated by a single operator. 
     
     
         14 . A method of assembly a snubbing assembly, a secondary BOP unit and a primary BOP stack onto a wellhead, said method comprising the steps of:
 a. providing an integrated snubbing platform comprising a snubbing section comprising a snubbing jack assembly and a secondary blowout preventer (BOP) connected to the snubbing jack assembly; and a primary BOP section connected directly to the secondary BOP; and   b. mounting the integrated snubbing platform onto a wellhead as a single unit.
