Invest in your aging assets intelligently.
More barrels lie below your feet. The challenge in legacy fields is knowing when to invest and when to walk away. As reservoir pressure drops and water and sand content increase, you can be forced into a never-ending game of reactive workovers and deferred production. From well surveillance to production optimization, to re-entry, and to plug-and-abandonment, we help you better understand and maximize the economic life of your aging assets.
Weatherford is an oil and gas service company with a presence in every major oil and gas region of the world. Our business is helping our clients to safely and sustainably find, drill, complete, and produce oil and gas fields.
Help move the shut-in point further down the production curve.
Our approach to production revitalization workflows is customizable consistency: We let well economics define the scope and intensity of work. We begin with production optimization using our comprehensive surveillance and analysis systems that help you refine and optimize your artificial-lift infrastructure, including the Field Office® software suite and OmniWell® downhole-sensing tools.
We then progress to wellbore optimization using geomechanical and seismic data from technologies such as our Compact™ cross-dipole (CXD) sonic tool. These technologies provide data that updates the reservoir model and characterizes the well for re-entry. Finally, we use the same principles from the well level and apply them reservoir-wide. We use behind-casing analysis and geological and petrophysical data to discover bypassed oil and new opportunities for production.
Monitor and optimize in real time.
Roving work crews can be a relic of the past. Rather than waiting for unexpected declines in production and equipment failures, we offer a suite of proactive technologies.
Our enterprise-wide well-monitoring and production optimization software systems remove the guesswork from artificial lift and reduce downtime. The FieldOffice® Suite―installed on over 480,000 wells around the world―provides accurate diagnostics, predicts failure, reduces power costs, and identifies optimization opportunities on a daily basis.
We also provide actionable data with well-level technologies. Our OmniWell® production-monitoring systems detect changes in pressure, flow, temperature, acoustics, and seismicity. Monitoring these changes can help accurately predict and diagnose production issues for the life of the well.
Enhance production well-by-well or field wide.
As well output gradually reverses from economic levels of oil and gas to uneconomic percentages of water, sand, and corrosive fluids, you need reliable equipment that maximizes drawdown, optimizes asset use, and minimizes costs.
Continual paraffin problems can sentence your well to a lifetime of costly workovers and waning profitability. Our advanced tools―including capillary injection technologies, sucker-rod guide/rod rotator combos, and the innovative ClearWELL™ scale and paraffin-control system―promote unrestricted production, reduced maintenance, and reduced downtime.
Our industry-leading production-enhancement tools include our self-mitigating and expandable sand screens, de-watering systems, multizone-refracturing systems, and an array of RFID-activated intervention tools.
We help you discover reserves beyond the wellbore.
You know your well. But what lies just outside the permeability of the near-wellbore region is both out of sight and out of reach. Meanwhile, the tight economics of field rejuvenation require knowing exactly what recoverables are available before drilling beyond wellbore.
Our reservoir and geomechanical analysis tools help you rediscover your wider asset. We provide high-resolution imaging and rock analyses zones that help you find bypassed or misdrilled zones, whether the source rock can be produced and whether more drilling is economically feasible. Our innovative Raptor™ cased-hole evaluation tools include a 5-detector array and LaBr3 sensors—both industry firsts that help overcome drawbacks of conventional pulsed-neutron tools.
Reach Further into the Reservoir.
We can help transform your aging wells into rejuvenated production highways. Once we’ve identified economic reserves of hydrocarbons, we can drill precise sidetracks from your aging wellbore, create an in-fill drilling program, and deliver onsite cuttings analysis calibrated by full-core laboratory studies.
Our QuickCut™ casing-exit system delivers single-trip efficiency in milling an exit window while leaving a rathole as small as 3 feet. We then drill an exacting sidetrack wellbore path using our Revolution® series of rotary-steerable tools. Our managed pressure drilling systems include underbalanced drilling and pressurized mud-cap drilling. They help you mitigate drilling hazards―including kicks and under- and over-pressured zones―when re-entering challenging or fragile formations.
We also help manage unstable formations with our drilling-with-casing (DwC™) and drilling-with-liner (DwL™) systems. These systems eliminate the need to trip pipe and bottomhole assemblies (BHAs), which increases drilling speed and reduces risk exposure by ensuring formation isolation on or near the bottom.
