Methods and systems for joint production and processing of hydrocarbons from natural gas hydrate reservoirs and existing hydrocarbon reservoirs

摘要

Producing hydrocarbons from a plurality of hydrocarbon containing reservoirs including at least one conventional hydrocarbon reservoir (22,24) and at least one natural gas hydrate reservoir (26) is described. The system also includes a production facility (34), including water separation apparatus (134,62), which is in fluid communication with the at least one hydrocarbon reservoir and the at least one natural gas hydrate reservoir. The production facility can separate hydrocarbons and water concurrently received from the first conventional hydrocarbon and the second natural gas hydrate reservoirs. The at least one hydrocarbon reservoir and the at least one hydrate reservoir can be concurrently developed. Or else, the at least one hydrate reservoir can be developed later in time and then fluidly connected to the production facility.
