Excellence in safety and quality service delivery...
Well Services
Our Well Services provide the Completion & Production Solutions safely, efficiently with innovation to maximize the flow of hydrocarbons and direct discrete production streams everywhere our clients operate. We move into action as soon as the drill bit is pulled out of hole, we deploy our equipment in time for action. From well construction components like premium connections, liner hangers and cementing equipment to downhole screen, Completion design, our tools allow operators to optimize the completion of a well.
Once a well is completed, our robust suite of wireline equipment allows for cost-efficient and reliable intervention work from the truck to the software to the BOP stack. From there, production begins. Whether on land or offshore, our highly-engineered equipment helps lift, pump, flow and separate oil, gas, water and sand streams on the surface or even subsea. Our variety of composite piping and structures helps to connect and carry product in even the most corrosive environments.
We are here with our new technologies engineered by NOV to solve the latest oilfield problems, and to help our clients achieve lasting success.

We bring together a portfolio of differentiated completion tool products and solutions to address the most pressing needs of the global well completions marketplace. Our tools, which broadly support horizontal multistage fracturing techniques, include the following product line groupings:
Multistage Completions:
We offer a variety of multistage fracturing completion from plug-and-perf systems and ball-drop systems to coiled tubing systems.
Well Construction:
We provide reliable completion products including liner hanger, Liner Packer and PBRs, liner hanger packers, liner cementing and accessories, and liner running and service tools to ensure your well integrity.
Downhole Monitoring:
Gathering and understanding dynamic data recorded during well operations are critical to success.
We offer our i-Con, i-Trace, and MaxTrace monitoring tools.
ReAct systems:
We offer remote signaling capabilities to downhole valves and sleeves with our ReAct product line, which includes circulation valves, electronic liner shoes, cleanout valves, tracer valves, inflow valves, up to tubing filler subs.
Intervention systems:
We offer various coiled tubing, wireline, and workover completion tools that can be customized to your well.
Conventional completion:
To support your onshore and offshore projects, we offer a growing suite of conventional completion solutions from production packers to subsurface safety valves and flow control systems.
Dissolvable products:
Our dissolvable balls and plugs can retain structural integrity under high temperatures and differential pressures for a specific range of time, dependent upon fluid conditions in the wellbore, before dissolving.
You can count on Houston Wells to install and provide top-quality completion equipment and running tools for your well.
GSP II Liner Hanger
Designed for deviated and horizontal holes, the GSP II liner hanger contains slips that are fully recessed into a special profile at the rotating body. This ensures trouble-free installation and uniform load distribution in the setting section. In set and non-set state, the GSP II liner` hanger allows a very high bypass, ensuring a high flow rate with low pressure loss.
Features & Benefits
- Non-weld design, one-piece body with premium threads.
- Slips are fully recessed and pocketed into a special profile at the rotating body to prevent from premature setting during running.
- Slips and cone are designed to minimize casing stress.
- Slips are designed and tested to hang inside a large range of casing weights.
- All hydraulic seals remain stationary during rotation of the liner.
- Improved seal stack in the hydraulic cylinder; HP/HT seals.
- Capable of hanging long, heavy liners with enhanced hanging capacity.
- Large annular flow area in set and unset position.
- Lock of slips prevents premature setting during running.
- Rotating/non-rotating (optional).

Integrated Liner Hanger Packer
SUREST Liner Hanger Packer
Designed for high differential pressures, the SURESET™ liner hanger packer is a complete liner hanger system built on a one-piece mandrel with no internal connections. The SURESET includes a packing element, an integral packoff nipple profile, and the hanger.
The hanger may be set using a hydraulic cylinder or, in some sizes, a mechanical set option is available. The SURESET packing element is available in multiple elastomer options for various applications and is activated with set down weight using a packer actuator. In addition to the internal snap ratchet, the hold-down slips keep the SURESET element in position against high differential pressures.
The hanger portion of the SURESET contains slips that are fully recessed into a special profile in the rotating body to ensure trouble-free installation and uniform load distribution in the setting section. In both the set and un-set positions, the SURESET liner hanger packer allows for high bypass, ensuring low ECDs (equivalent circulating density).

The ReAct completion circulation valve incorporates technology to enable downhole tools to be remotely activated without control lines or intervention runs.
The ReAct™ Completion Circulation Valve (RCCV) is a remotely activated completion valve that is run above the upper completion production packer. The valve incorporates our unique ReAct technology, which allows downhole tools to be remotely activated without the need of control lines or intervention runs. The valve offers significant cost and time savings compared to conventional operations. Dependent on the well design, either multiple wireline runs can be eliminated or, in many cases, entire middle completion strings can be eliminated, saving both significant rig time and cost.
The RCCV can be deployed above any packer and is run closed to allow for packer setting and packer/tubing testing. Once the production packer is set, the operator can pressure test the tubing against the closed RCCV. Applying increased annulus pressure then bursts a ruptured disk to open communication ports to circulate between the tubing and the annulus and vice versa. Once the tool is open, tubing fluid is then circulated out to a lighter fluid to allow the well to flow naturally. The valve is then closed by applying a ReAct pressure signal.
In addition to fully redundant primary and backup ReAct modules, the RCCV has full mechanical redundancy with a standard mechanical shifting tool in the unlikely event that it is not possible to activate any of the ReAct modules. The RCCV has great flexibility, as all of the operational parameters are fully adjustable until deployment.
