Abstract
A method of deploying a pump in a well production tubing using an electrical cable includes attaching a downhole barrier valve (DBV) to a spoolable conveyance. The DBV is closed to flow in both directions until a differential pressure across the DBV exceeds a first threshold. The DBV is closed to flow when the differential pressure falls below the first threshold. The DBV is moved to a selected depth in the well by extending the conveyance through a lubricator attached to a wellhead at an upper end of the production tubing. The spoolable conveyance is withdrawn from the well. The pump is attached to the electrical cable and is moved through the wellhead and the production tubing by extending the cable until the pump reaches a selected setting depth in the well.
