Drilling
Weatherford has created a portfolio of drilling services and products that make well construction safer, reduce nonproductive time and enhance reservoir deliverability.
Drilling Services
The latest-generation logging-while-drilling (LWD) systems that allow some of the fastest logging speeds and possesses some of the world’s highest temperature and pressure ratings.
Revolution® rotary-steerable systems (RSS) that are the industry’s first 4 3/4-in. slimhole point-the-bit RSS. Our system provides more precise steering and smoother, cleaner wellbores.
Measurement-while drilling (MWD) systems specifically designed for deep-well and HTHP hostile drilling environments. Our system is rated to an operating temperature of up to 356°F (180°C), a survival temperature of 392°F (200°C), and a survival pressure up to 30,000 psi (207 MPa).
Controlled Pressure Drilling® (CPD®) systems for underbalanced, air and managed-pressure drilling applications. Current focus areas are rotating control devices, downhole deployment valves, electromagnetic MWD and LWD systems, and surface separation systems.
Drilling-with-casing (DWC™) and drilling-with-liner systems that permit the simultaneous drilling, casing and evaluation of oil and natural gas wells. The technologies eliminate downhole complexity, reducing expensive rig modifications and the number of trips downhole.
Well Construction
OverDrive™ casing running and drilling system that does what conventional tools cannot: rotate and push down the casing while running to help prevent differential sticking and achieve high-speed string rotation with the top drive when drilling with casing. It also removes people from hazardous rig floor operations to reduce risk exposure.
Cementation tools such as the patented MudMaster™ II filter shoe, designed for use in critical environments and high-inclination wells especially sensitive to surge pressure and well debris.
MetalSkin® expandable tubular technology that reduces installation risks while driving down well construction costs and mitigating drilling hazards.
Drilling Tools
LoTAD™system, a complete mechanical friction-reduction system designed for extended-reach wells. Reduces torque, drag, casing wear, tool-joint wear and differential sticking while also improving directional control, ROP and hole cleaning.
