Embodiments described herein relate to injecting steam into a wellbore using a device. The device includes a body having a bore configured to communicate steam through the body. The device also includes a sleeve movable in the bore of the body between a first position and a second position, wherein the sleeve in the first position blocks steam from exiting an opening of the body and the sleeve in the second position allows steam to exit the opening of the body. The device can be activated by an activation device conveyed down a tubing string and can include a seat on which the activation device. The seat is expandable to allow the activation device to pass.

Steam diversion assembly

A stand-alone frac liner that allows for fracturing of multiple lateral legs of a multilateral well on a single call out and rig-up of fracturing equipment. Tools and techniques are provided that include setting multiple stand-alone frac liners in multiple lateral legs of the multilateral well. The liners may rest in the legs physically untethered to surface equipment. Thus, a single call out of a frac string tubular and associated equipment may be used to frac the lateral legs in sequence from one leg to the next. This may be achieved without the requirement of removal of the tubular from the well or disconnect of surface fracturing equipment between the lateral fracture applications. Thus, a considerable amount of expenses associated with time and manpower may be saved.

Structurally stand-alone FRAC liner system and method of use thereof

A downhole service tool is provided that may include a body having an interior passageway, at least one exit port through which fluid may flow from the interior passageway to an exterior of the tool, and at least one diverting channel adapted to cause fluid exiting the exit port to flow in a predetermined pattern, such as a helical or rotational flow path. The diverting channel may be in the form of a trough, and may also have a tapering width from its upper end to its lower end, where it meets the exterior of the tool. The diverting channel may also have a helical or other predetermined shape so as to facilitate the inducement of the desired flow pattern. By designing the tool so as to create a desired flow pattern, erosion of the tool by the exiting fluid flow is lessened. Related methods are also provided.
