Downhole spread eases West Africa well completion

Offshore staff

ABERDEEN, UKRed Spider has completed a downhole operation offshore Equatorial Guinea using eRED-FB technology.

The equipment provides a downhole barrier that can be opened and closed remotely, removing the need to set a plug via conventional intervention methods.

In this case, eRED-FB eliminated deep-set interventions during the completion placement phase of the subsea horizontal well. The system was deployed as an integral part of the tubing string, and run in-hole in the open position to a depth of 9,100 ft (2,773 m) at a deviation exceeding 80°.

During the operation it was remotely operated twice using pre-programmed pressure and time commands, first closing the tool to provide a means to set the packer and test the tubing integrity, then opened with maximum flow area maintained for production.

According to Red Spider, the equipment should deliver savings of between 32 to 38 hours ($650,000-$800,000) by dispensing the need for wireline runs during a completion placement operation.

This approach also brings wells onstream sooner and reduces the risk of exposure to bad weather.
