Discover Weatherford’s Cased-Hole Completions We may have more to offer than you realize. Weatherford is not new to the cased-hole completions industry. In fact, we made our first foray into the business in the early 1970s. Since that time we have diligently expanded our portfolio through a combination of acquisitions and internal growth.

Product advancements for today’s completions challenges. Along the way, we have introduced many innovative technologies. Like the HellCat™ 2 production packer for intelligent wells, the WDB safety valve for wells with damaged sealbores, the FormationSaver™ valve for ESP wells, and the FracGuard™ composite bridge plug. Our technology portfolio enables us to address virtually any completion need, from everyday applications to the extreme environments and challenges that face the industry today.

Intelligent Completions

More than conventional products and services. Our rich history represents an evolution into what we are today—a premium cased-hole completions provider and a high-value resource for maximizing your well completion success. That means more than offering a full suite of conventional completion products. It’s more than creating custom-engineered systems for every possible application and more than having experienced and knowledgeable experts.

It’s all of those things, plus a service ethic focused on helping you design the most efficient completion for your well. It’s how we think. It’s how we’re organized. And it’s how we deliver.

It’s time for you to discover Weatherford’s cased-hole completions.

Discover a custom-engineered system for your toughest wells. Our engineered completion designs can have a real impact on your success—like in West Africa where the completion need was dual-zone flow control coupled with individual zonal-production allocation data without further drilling or intervention. Weatherford developed the selective dual-zone-producer design for this deepwater application— blending the company’s expertise in expandable sand screens, packers, safety valves, intelligent completion, flow control and optical sensing technologies to enable improved reservoir recovery.

Innovative designs for demanding applications. Our completion design engineers provide an agile response to meet your cased-hole completion challenges. By using specialized metallurgy, unique sealing systems, optimized equipment dimensions and performance ratings, specialized threads and many other crucial options, we address the most demanding well applications: • Unconventional hydrocarbons • Deepwater locations • Selective zonal stimulation and production • Extended-reach and horizontal wellbores • Deep wellbores • H2S and CO2 environments • High-pressure/ high-temperature environments

A selective dual-zone-producer completion blending Weatherford’s expertise in, packers, safety valves, intelligent completion, flow control, sand control and optical sensing technologies to enable production management and improved reservoir recovery without well intervention.

Answer

Design a deepwater West Africa well in multiple poorly consolidated formation sands. Provide well control during installation, production and workover. Enable zonal-production allocation and life-of-well production and reservoir management, avoiding well intervention to minimize operating expenditures.

Discover Innovative Design

HellCat™ 2 hydraulic-set production packer provides single-trip speed and efficiency for intelligent completions.

We offer a range of flow-control tools and systems comprising downhole barrier valves, check valves, packer setting valves, fluid loss valves, and sliding sleeves for a variety of applications, including coiled tubing, slickline, multizonal, electric submersible pumps, sand control and multilaterals.

VooDoo™ valve offers a simple, reliable method for testing the tubing and setting packers without intervention or restricting the well ID, which reduces risk and saves rig time.

Weatherford’s Uniset® flow-control system optimizes premium completion designs. Each type of flow control accessory—plugs, equalizing assemblies, anti blowout devices and standing valves—has been integrated into an intervention system that maximizes the efficiency of every flow-control deployment.

Uniset® tubing hanger profile allows installation of tubing hanger plugs or back pressure valves for Christmas tree installation and temporary wells suspension.

Splice sub contains and protects spliced connections of control lines in a multizone intelligent completion.

Chemical injection mandrel receives chemical-injection valves, thereby enhancing production, remediating corrosion effects and prolonging completion life.

In only five years, Weatherford has grown to be the third largest supplier of safety valves. We recently shipped our 2000th safety valve.

Optimax™ tubing retrievable surface-controlled subsurface safety valve provides a selfequalizing emergency safety barrier while allowing bypass of hydraulic control lines, injection lines, and instrument cables.

OptiSleeve™ non-elastomeric sliding sleeve isolates producing zones during installation of inner string.

Barrier plug isolates and temporarily suspends the outer string, latched as the intermediate string is run through the liner top.

EXR hanger/packer allows single-trip running, setting, and expansion of sand control completion.

Weatherford has more than 40 years’ experience in providing packer systems and completion

ThunderCat™ packer provides zonal isolation with one-trip setting with no rotation or reciprocation of the tubing string; ideally suited for deep, high-pressure completions.

ROSS/ROSS V sliding sleeve

Weatherford’s intelligent-well competency combines optical sensing technology and hydraulically actuated flow control systems. This combination enhances reservoir management and optimizes production.

ROSS® remotely operated sliding sleeve/ROSS V remotely operated variable sliding sleeve allows alterations to the completion in response to changing reservoir conditions without wellbore intervention; provides open-close or variable functionality to control production from the two reservoir intervals.

Beyond the intelligent-well application shown here, we have packers available for other demanding applications, such as subsea completions, deviated and horizontal wells, zonal isolation—as well as electric submersible pumps and other artificial-lift systems.

Weatherford offers a full suite of in-well permanent monitoring systems including optical sensors, flow meters, distributed temperature sensing and seismic, along with our conventional electronic quartz and strain gauges.

Optical P/T gauge mandrel permanently monitors tubing and annulus flowing conditions to inform production and reservoir management decisions.

Nipple profile for flow control installation receives plug or standing valve for packer setting contention or testing.

OptiSleeve sliding sleeve

ThunderCat™ packer

Sealbore provides high integrity isolation between upper and lower producing zones once the inner string has been installed.

Shifting tool for OptiSleeve sliding sleeve

Seal unit/locator provides high integrity isolation between upper and lower producing zones once the inner string has been installed.

Shifting tool opens the OptiSleeve sliding sleeve as the inner string is installed to establish a flow-path for the producing zones.

Inner string

accessories for a wide range of downhole conditions, including: high-temperature/high-pressure, highly deviated and extended reach, H2S and CO2 conditions, zonal isolation and deep water.

Intermediate string

Our fixed-position gravel pack system simplifies operations, maintains squeeze and circulating modes with the work string and tools in a “weight-down” state, holds the work string steady against thermal forces and rough seas, and gives more control over sand-control treatments.

Screen (gravel pack, stand alone screens, or ESS® expandable sand screen systems) prevents sand ingress to maximize productivity and optimize reliability.
