SUBSEA, VERTICAL, ELECTROMAGNETIC SIGNAL RECEIVER FOR A VERTICAL FIELD COMPONENT AND ALSO A METHOD OF PLACING THE SIGNAL RECEIVER IN UNCOMPACTED MATERIAL |
摘要 |
A vertical receiver antenna device includes first and second receiving, electrode units interconnected by a receiver antenna cable and connected to means for the electromagnetic surveying of electrically resistive targets potentially containing hydrocarbons. The receiver antenna is arranged in a tubular, non-magnetic antenna housing arranged vertically in subsea uncompacted material, and one of the first and second receiving electrode units being connected in a electrically conductive manner to the underlying structure, and the other one of the first and second receiving electrode units being arranged in a portion of the antenna housing distantly from the first one of first and second receiving electrode units. A method of installing a vertical receiver antenna in subsea uncompacted material is also described, |
