1. A method of deploying a pump in a well production tubing using an electrical cable, comprising:
attaching a downhole barrier valve (DBV) to a spoolable conveyance, the DBV closed to flow in either an upward direction or a downward direction, the DBV opening to flow only when a predetermined differential pressure across the DBV is obtained, the DBV closed to flow when a differential pressure across the DBV exceeds a predetermined threshold in either the upward direction or the downward direction, and the DBV closed to flow when the differential pressure falls below the predetermined threshold;
moving the DBV to a first selected depth in the well by extending the spoolable conveyance through a lubricator attached to a wellhead at an upper end of the production tubing and setting the DBV at the selected depth;
withdrawing the spoolable conveyance from the well;
attaching the pump to the electrical cable; and
moving the pump through the wellhead and through the production tubing by extending the electrical cable until the pump reaches a pump setting depth in the well.
