Abstract: A transport system has a dedicated trailer for transporting a small transport reel (i.e., <18-ft in diameter) of continuous rod to the field. The trailer has a pedestal that can pivot the reel. A hub motor on the pedestal can turn the reel, and a transfer unit and rod bender on the trailer can curve or straighten the rod when being fed into or out of the reel. A power and hydraulic system operates the various hydraulic components on the trailer. In other aspects, the transport system includes stands that can hold the small transport reels on a trailer within a defined transport envelope. When empty, these stands can be stacked on top of one another on the trailer for return to a facility.

Abstract: Embodiments of the present disclosure generally relate to apparatus and methods for connecting continuous sucker rods. Ends of two work pieces may be prepared by reducing cross sections of the ends. The two work pieces may be welded together by establishing a planar contact at the prepared ends and applying a current across the two work pieces while moving the work pieces relative to each other.

Abstract: A continuous rod transport system has a reel with a cage and a removable hub. The cage has support members interconnected by rings to hold the rod coiled in the cage. The removable hub has extending arms that removably attach to the cage's support members. Locks on the ends of the arms can removably lock the hub to the cages. Because the hub is removable, the cage with coiled rod can be shipped separate from the hub, thereby significantly reducing the transportation weight. Preferably, the cage has a diameter of 14-ft so two cages can be held on a stand and can be transported in overseas containers. In this way, the coiled rod in the cage can be transported to various areas in less costly and time-consuming ways than currently available.

Abstract: A shear coupling assembly utilizes a second coupling member, a first coupling member and a locking member which is inserted into a bore in the first coupling member to connect between the second coupling member and the first coupling member. In embodiments where a pretension is applied to the shear neck, the locking member maintains the pretension in the shear neck. The bore of the first coupling member has a profiled section which corresponds to a profiled section on the second coupling member which when mated together permit torque to be transferred for co-rotating the second coupling member with the first coupling member for use in rotary pump operations. Advantageously, the profiled portions and the shear neck are encased in the bore of the shear coupling assembly and are protected from corrosive wellbore fluids.
