Claims21
An apparatus for one trip drilling and completion of a well, comprising:
- a tubular having at least one opening and an extendable sand control device associated with said opening, said sand control device comprising an outwardly extending tubular element selectively extendable relative to said opening where it is mounted;
- a drilling apparatus further comprising a drill string supporting at least one bit, said drilling apparatus rotating and advancing said tubular as said bit drills the well;
- and
- a temporary blocking medium for said sand control device said blocking medium being adapted to initially block fluid flow through said sand control device as said sand control device is extended and said tubular is externally sealed in the well with a sealing material delivered through it and to subsequently allow fluid flow through said extended sand control device and said now externally sealed tubular after said sealing material has set up.
