WELLBORE INSTALLATION APPARATUS AND ASSOCIATED METHODS

摘要

The invention relates to an apparatus (10) for installing a wellbore (12) on a seabed (14). The apparatus includes a suction member (16) including a housing (17) defining a chamber (18). The housing (17) has an open end (20). The open end (20) defines a leading edge (22) for engagement with the seabed (14).The apparatus (10) includes a wellhead located (24) at an end opposite the open end (20) for engagement with a conduit (28). The conduit (28) is coupled to the housing (17). The conduit (28) extends from the wellhead means (24) through the chamber (18). When the wellbore (12) is installed on the seabed, the apparatus (10) provides a barrier or well barrier, which is capable of isolating and/or maintaining a wellbore pressure. The apparatus (10) allows for the installation of a wellhead (24) and/or a conduit (28) without the need of prior drilling and/or jetting operations at a wellbore site.

主权项

1. An apparatus for installing a wellbore on a seabed comprising
a suction means comprising a housing defining a chamber, the housing having an open end, wherein the open end defines a leading edge for engagement with the seabed, a wellhead means located at an end opposite the open end for engagement with at least one conduit, the at least one conduit being coupled to the housing, wherein the at least one conduit extends substantially from the wellhead means through the chamber, when the wellbore is installed on the seabed, the apparatus provides a barrier or well barrier, which is capable of isolating and/or maintaining a (internal) wellbore pressure.
