Running, pulling and test toolsTalk to an expert
Halliburton service tools consist of running tools, pulling tools and test tools. Running tools are designed for horizontal subsea trees, featuring metal-to-metal and composite packing stack. The pulling tools are used during wireline operations to unlock and pull a variety of subsurface controls with internal fishing necks. The test tools enable communication bewtween the tubing/casing annulus.

Otis® X® and R® Running Tools
Otis® X® and R® running tools are used to set Otis X, XN®, R, RN®, and RQ lock mandrels in their respective Otis landing nipples. These tools are designed with locator dogs serving to locate the proper landing nipple and positioning the lock mandrel before locating and locking. By selecting the position of the running tool, lock mandrel keys can be placed in the locating or retracted position.
DPU downhole power unit
The Halliburton DPU® downhole power unit is a battery-powered, rig-safe, non-explosive electromechanical tool that expands well intervention capabilities. By generating a slow, precisely controlled linear force, the DPU tool optimizes settings and helps ensure maximum well completion performance, even in the most high-risk environments. With the advanced measurement system (AMS) for accurate depth control, the slickline-conveyed DPU tool performs reliable and flexible well intervention solutions beyond conventional methods.
Internal fishing necks
Otis® GS and GR pulling tools are used during wireline operations to unlock and pull a variety of subsurface controls with internal fishing necks, including Otis G pack-off assembly, Otis D bridge plugs, Otis X® and R® lock mandrels, Otis D mandrels, and Otis D collar stops.
External Fishing Necks
The Otis S and R pulling tools are designed to engage external fishing necks on subsurface devices within the wellbore. These pulling tools consist of a cylinder complete with top sub, inner core, and spring-loaded dog set. After the Otis S pulling tool is engaged on an external fishing neck, downward jarring action shears a pin to release the spring-loaded dogs and enable tool retrieval.. Once the Otis R pulling tool is engaged on an external fishing neck, an upward jarring action shears a pin to release the spring-loaded dogs and enables tool retrieval. When used as a running tool, the core must be long enough to allow upward travel after shearing the pin before the skirt is stopped by the equipment being run. This action permits complete release of the running tool.
The DuraSleeve® Sliding Side-Door® circulation and production sleeve
The DuraSleeve Sliding Side-Door circulation and production sleeve is a full opening device with an inner sleeve that can be repeatedly opened and closed to gain communication between the tubing/casing annulus. A nipple profile in the top sub and a polished bore in the bottom sub are standard features, which allow accessory tools such as a Side-Door choke or separation tool to be set across the DuraSleeve device.
