Attempt in SZ36-1 Oilfield by In-Stiu Carbon Dioxide Generation

The technology of in-stiu carbon dioxide generation plays multiple roles, including sealing high-permeability layers, hot plugging and flooding etc. By using this technology effectively, the water cut can be controlled and oil production can be stabilized during the oil and gas field development process. This technology is simple for operation, suitable for offshore oil and gas fields in the narrow working space. This technology has been used in SZ36-1 Oilfield in Bohai Sea. Through application in Well H5 of SZ36-I Oilfield in Bohai Sea, the oil production has been increased and water cut has be controlled effectively, and oil production has been increased nearly by 10% during three months after the application of this technology.
