Abstract

A system comprising a mobile offshore drilling unit, a first group of wells drilled by the mobile offshore drilling unit, a second group of wells drilled by the mobile offshore drilling unit comprises processing equipment adapted to process production from the first group of wells and the second group

1 . A system for drilling and producing subsea fields, comprising:
 a mobile offshore drilling unit;   a first group of wells drilled by the mobile offshore drilling unit;   a second group of wells drilled by the mobile offshore drilling unit;   
     wherein the mobile offshore drilling unit comprises processing equipment adapted to process production from the first group of wells and the second group of wells . 
   
   
       2 . The system of  claim 1 , further comprising a first manifold adapted to collect production from the first group of wells. 
   
   
       3 . The system of  claim 1 , further comprising a second manifold adapted to collect production from the second group of wells. 
   
   
       4 . The system of  claim 2 , wherein the first manifold is connected to the second manifold by a flow line. 
   
   
       5 . The system of  claim 1 , wherein the mobile offshore drilling unit is floating. 
   
   
       6 . The system of  claim 1 , further comprising a gas and a liquid export line connected to the mobile offshore drilling unit. 
   
   
       7 . The system of  claim 1 , further comprising a third group of wells drilled by the mobile offshore drilling unit. 
   
   
       8 . A method of drilling and producing subsea fields comprising:
 drilling a first group of wells with a mobile offshore drilling unit;   connecting the first group of wells together with a first manifold;   drilling a second group of wells with the mobile offshore drilling unit;   connecting the second group of wells together with a second manifold;   connecting the first manifold to the second manifold with a flow line;   connecting at least one of the first manifold and the second manifold to the mobile offshore drilling unit with a flow line; and   processing production from the first group of wells and the second group of wells with the mobile offshore drilling unit.   
   
   
       9 . The method of  claim 8 , further comprising drilling a third group of wells with the mobile offshore drilling unit and connecting the third group of wells together with a third manifold.
