    摘要： Support systems, apparatus and methods for use with well structures, which may be used to reduce the cost and/or risk of performing procedures on assets, for example, prior to or during well abandonment. A support system includes an actuation system for use with a support member. The support member may be configured for complementary engagement with the actuation system. A cross-over section is configured for use at a lower end of the support member and includes a body portion and a well structure portion. The bore of the cross-over section changes from a first diameter at the body portion to a second diameter at the well structure portion, the second diameter being greater than the first diameter.

    摘要： The invention relates to a modular drilling rig system comprising multiple components, which system is transfigurable between a transport mode and an operational mode, and comprises: a. a drilling rig mast which is positionable in a vertical orientation; b. a base structure adapted to be positioned on a surface near the well center to support the drilling rig mast thereon, wherein the base structure comprises two elongated members that are connected to each other by a cross beam; c. a displacement system to displace the drilling rig with respect to the surface in a horizontal direction; wherein the displacement system is configured to displace the two elongated members of the base structure together in order to displace the drilling rig, and is configured such that the two elongated members can be displaced with respect to each other when the two elongated members are not connected to each other.
