Methods and systems (10) of placing off-shore wells (12) on production comprising the steps of separating a gas from oil or oil from water produced by the well (12), introducing the gas into the seawater surrounding the well (12) at a depth where the temperature and pressure of the seawater are such that solid gas hydrates are formed when the gas is mixed with the seawater, mixing the gas with the seawater whereby the gas is converted to solid gas hydrates and depositing the solid gas hydrates on the sea floor.
