A packer is used for setting downhole in tubing subject to downhole flow at a high flow rate. The packer includes a setting element, a slip element, and a packing element. The setting element is disposed on the packer toward an uphole end and is activated hydraulically to move in a downhole direction toward a downhole end of the packer. The slip element is disposed toward the downhole end and is moveable outward toward the tubing in a first stage in response to the movement of the setting element. The packing element is disposed on the other elements and is at least partially carried by the setting element. The packing element is compressible outward toward the tubing in a second stage, after the first stage, in response to the movement of the setting element. Additionally, a choke ring or other element disposed on the packer at least downhole of the packing element can move outward toward the tubing in response to the setting movement to restrict the downhole flow in the annulus to a lower flow rate.

A go-cart frame and a tricycle frame that can be attached to an engine frame. Both the go-cart frame and tricycle frame have a mounting bracket that attaches to a bracket on the engine frame. The engine frame has an engine mount, a transmission system and two wheels. The go-cart frame has two wheels in the front, a front steering systems, a body with a seat and throttle and brake controls. The tricycle frame has a single front wheel, a steering system, a seat and throttle and brake controls. To convert one device to the other, the user simply unbolts the engine frame from the other frame (supporting it as needed), disconnects the control cables, moves the originally connected piece, moves the other piece into position, and then bolts this new piece to the engine frame and reconnects the controls. Then, the new configuration is ready to use.

Herein disclosed is a mechanism for providing high load capabilities in downhole locations. The mechanism comprises tubulars, at least one of which is constructed from composite; and the tubular composite being for high load capabilities in connecting the tubulars. In some cases, there are at least two tubulars in the mechanism. In some cases, the mechanism comprises a thread form, which thread form is mounted to translate an axially directed force into a radially directed force. In some cases, the high load capabilities include a load bearing flank angle of 15&#xb0; to 50&#xb0; as measured from the axis of said tubular. In some cases, the high load capabilities include a clearance flank angle of 15&#xb0; or less as measured perpendicular to the axis of said tubular. In some cases, at least one of the tubulars includes a thread pitch, having from 2 to 12 threads per inch.

A downhole tool for use in a well has a mandrel with an expandable sealing element disposed thereabout. The mandrel has a head portion threadedly connected thereto. A shoulder in the head portion and an upper end of the mandrel define an annular space. A sleeve with a bore therethrough may be positioned in the annular space. The head portion may be removed and a solid plug installed so that it fits within the annular space and so that the downhole tool will act as a bridge plug. The downhole tool has slip rings made up of a plurality of individual slip segments that are adhesively bonded to one another at the sides thereof.

A downhole tool releasing mechanism which includes a collet for releasably engaging a mandrel of a downhole tool. A retaining band is circumferentially disposed about the fingers of the collet for maintaining engagement of the collet and the mandrel prior to application of a predetermined axially directed force on the releasing mechanism. Upon application of such a force the collet fingers expand, breaking the shear band, the mandrel is released and the downhole tool is disengaged.

A bridge plug having a segmented backup shoe, and at least one split cone extrusion limiter, the extrusion limiter comprising a two part conical retainer positioned between packer elements and the segmented backup shoe to block packer element extrusion though spaces between backup shoe segments. In one embodiment, two split cone extrusion limiters are used together and positioned so that each split cone extrusion limiter covers gaps in the other extrusion limiter and together the two split cone extrusion limiters block packer element extrusion though gaps between backup shoe segments regardless of their orientation relative to the segmented backup shoe. In one embodiment, a solid retaining ring is positioned between a split retaining cone extrusion limiter and a packer element and resists extrusion of packer elements into spaces in the split cone extrusion limiter or limiters.
