METHODS OF REMOVING A WELLBORE ISOLATION DEVICE USING GALVANIC CORROSION |
摘要 |
A wellbore isolation device comprises: at least a first material, wherein the first material: (A) is a metal or a metal alloy; and (B) is capable of at least partially dissolving when an electrically conductive path exists between the first material and a second material and at least a portion of the first and second materials are in contact with an electrolyte, wherein the second material: (i) is a metal or metal alloy; and (ii) has a greater anodic index than the first material. A method of removing the wellbore isolation device comprises: contacting or allowing the wellbore isolation device to come in contact with an electrolyte; and allowing at least a portion of the first material to dissolve. |
