Claims

exact text as granted — not AI-modified
1 . A long offset gas condensate production system comprising: one or more subsea production wells; a subsea separator; and a subsea cooler. 
     
     
         2 . The long offset gas condensate production system of  claim 1 , wherein each of the one or more subsea production wells are connected to a subsea manifold by one or more flowlines. 
     
     
         3 . The long offset gas condensate production system of  claim 1 , wherein the subsea cooler is connected directly to the one or more subsea production wells through one or more flowlines. 
     
     
         4 . The long offset gas condensate production system of  claim 2 , wherein the subsea cooler is connected directly to the subsea manifold through a flowline. 
     
     
         5 . The long offset gas condensate production system of  claim 1 , wherein the subsea separator is directly connected to the subsea cooler through a flowline. 
     
     
         6 . The long offset gas condensate production system of  claim 1 , wherein the subsea separator is directly connected to the one or more subsea production wells by one or more flowlines. 
     
     
         7 . The long offset gas condensate production system of  claim 2 , wherein the subsea separator is directly connected to the subsea manifold through a flowline. 
     
     
         8 . The long offset gas condensate production system of  claim 1 , wherein the subsea separator comprises a three-phase separator. 
     
     
         9 . The long offset gas condensate production system of  claim 1 , further comprising a water injection well. 
     
     
         10 . The long offset gas condensate production system of  claim 1 , further comprising a subsea pig launcher. 
     
     
         11 . The long offset gas condensate production system of  claim 1 , further comprising a paraffin injection point. 
     
     
         12 . A long offset gas condensate production system comprising: one or more subsea production wells; a subsea separator; a subsea compressor; and a subsea cooler. 
     
     
         13 . The long offset gas condensate production system of  claim 12 , wherein each of the one or more subsea production wells are connected to a subsea manifold by one or more flowlines. 
     
     
         14 . The long offset gas condensate production system of  claim 12 , wherein the subsea cooler is connected directly to the one or more subsea production wells through one or more flowlines. 
     
     
         15 . The long offset gas condensate production system of  claim 13 , wherein the subsea cooler is connected directly to the subsea manifold through a flowline. 
     
     
         16 . The long offset gas condensate production system of  claim 12 , wherein the subsea separator is directly connected to the subsea cooler through a flowline. 
     
     
         17 . A method of transporting gas and condensate across a subsea floor comprising:
 providing a long offset gas condensate production system;   providing a subsea production stream;   cooling the subsea production stream to form a cooled subsea production stream;   separating the cooled subsea production stream into a produced water stream and a combined gas and condensate stream;   and transporting the combined gas and condensate stream across the subsea floor.   
     
     
         18 . (canceled) 
     
     
         19 . (canceled)
