摘要
A method for drilling and completing a hydrocarbon production well comprises the steps of: A) drilling a section of a borehole into an underground formation; inserting a casing into the drilled borehole section and radially expanding and securing the casing within said borehole section; B) lowering a drill bit through the expanded casing and drilling a subsequent section of the borehole; inserting a next casing into said subsequent section of the borehole and radially expanding and securing said next casing within said subsequent borehole section; and C) repeating, if required, step B a number of times until the borehole has reached the vicinity of a hydrocarbon bearing formation. The next casing is installed so as to co-axially overlap with the previously installed casing, and in that said next casing is expanded against the previously installed casing so as to further expand the previously installed casing.
