Method and system for jointly producing and processing hydrocarbons from natural gas hydrate and conventional hydrocarbon reservoirs

A hydrocarbon production system comprising:

• a first conventional hydrocarbon reservoir containing water and hydrocarbons including at least one of oil and natural gas;
• a second natural gas hydrate reservoir containing natural gas hydrates;
• and
• a production facility, including water separation apparatus, in fluid communication with the first conventional hydrocarbon reservoir and the second natural gas hydrate reservoir;
• wherein the production facility can separate hydrocarbons and water concurrently produced from the first conventional hydrocarbon and the second natural gas hydrate reservoirs.

A method of developing hydrocarbon production from hydrocarbon containing reservoirs, the method comprising:

• developing a first conventional hydrocarbon reservoir containing water and hydrocarbons including at least one of oil and natural gas;
• developing a second natural gas hydrate reservoir containing natural gas hydrates;
• constructing a production facility including water separation apparatus;
• and
• fluidly connecting the first conventional hydrocarbon and second hydrate reservoirs with the production facility;
• whereby a first mixture of hydrocarbons and water from the first conventional hydrocarbon reservoir and a second mixture of natural gas and water concurrently produced from the second natural gas hydrate reservoir can be separated into water and at least one of the gas and oil by the production facility.

A method of jointly developing hydrocarbon production from hydrocarbon containing reservoirs, the method comprising:

• a) developing a first conventional hydrocarbon reservoir containing water and hydrocarbons including at least one of oil and natural gas;
• b) concurrently developing a second natural gas hydrate reservoir containing natural gas hydrates;
• c) producing a first mixture of water and hydrocarbons including at least one of oil and natural gas from the first reservoir and transporting the first mixture to a production facility;
• f) concurrently producing a second mixture of water and natural gas from the second reservoir and transporting the second mixture to the production facility;
• g) processing the first and second mixtures utilizing the production facility to separate the water and produce at least one of natural gas and oil;
• wherein the water cut of the first reservoir increases while the hydrocarbons decrease over time and the water cut of the second reservoir decreases while the natural gas increases over time.
