| titleOfInvention | Method and apparatus for selective treatment of a perforated casing |
| abstract | The invention provides a method of treatment of a zone of a well, wherein inside the well, a wellbore in a formation is filled with a tube which is permeable to a material, the tube forming an annulus with the wellbore, and the zone being localized beyond the tube in the annulus and/or in the formation, and wherein the method comprises the steps: (i) placing inside the tube a setting section surrounded by a sleeve near the zone to treat, the sleeve being expandable and impermeable to the material; (ii) inflating the sleeve so that the sleeve is in contact with the tube near the zone to treat, ensuring for a first zone of the tube impermeability to the material, but leaving a second zone permeable to the material; (iii) pumping a treatment fluid to the zone to treat, the treatment fluid passing into the annulus via the second zone still permeable to the material; and (iv) treating the zone to treat with the treatment fluid. Also, the invention provides an apparatus for treatment of a zone of a well, the zone being localized beyond a tube placed inside the well and forming an annulus with a wellbore, the tube being permeable to a material, and the apparatus comprising: (i) a setting section surrounded by a sleeve, the sleeve being expandable and impermeable to the material; (ii) an inflating means for inflating the sleeve, the inflating means ensuring that the sleeve is in contact with a first zone of the tube so that the first zone of the tube becomes impermeable to the material; and (iii) a delivery opening for delivering a treatment fluid to the zone to treat, the delivery opening ensuring that the treatment fluid passes into the annulus via a second zone still permeable to said material. |
