The present invention relates to a completion method for implementing a casing in a well containing liquid and having a top. The method comprises the steps of providing a one-way valve in a casing wall in a first end of the casing, filling the whole casing with gas before the casing is implemented in the well, lowering the casing into the well while the liquid in the well prevents the gas from escaping through the valve, and introducing the first end of the casing into a substantially horizontal part of the well, whereby the gas provides buoyancy to the first end of the casing while moving the casing further into the well. Furthermore, the invention relates to a downhole system for carrying out a completion method. |
