Drilling fluids

Drilling fluids—commonly referred to as drilling mud—are vital to oil and gas well construction. These engineered fluids perform multiple critical functions: 

• Cooling and lubricating the drill bit to prevent overheating and wear
• Transporting rock cuttings to the surface
• Stabilizing the wellbore and managing downhole pressures to prevent the influx of formation fluids.

Drilling fluids are generally classified into three types: water-based drilling fluids, oil-based and other non-aqueous drilling fluids, and gaseous and foam drilling fluids. Each type is selected based on the formation geology, environmental constraints, and specific well design requirements.

Baker Hughes offers advanced drilling fluid solutions designed for performance across the most complex and extreme drilling environments—including deepwater, unconventional, high-pressure/high-temperature (HP/HT), and remote onshore wells.

We develop high-performance additives, polymers, and lubricants tailored to every drilling mud system—whether oil-based, water-based, or synthetic-based. Our Intelligent Fluid Solutions framework is built on three pillars:

• Digital enablement: We integrate software, automation, and artificial intelligence to improve wellbore stability, boost rates of penetration (ROPs), and minimize environmental and safety risks
• Advanced formulation: We create specialty drilling fluid systems and completion fluids to meet evolving regulatory and operational demands
• End-to-end service: Beyond fluids, we partner with customers to develop solutions-based services for solids and fluid waste management and streamline wellsite operations for greater efficiency

Absolutely. Our global Drilling and Completion Fluids experts bring decades of experience to every project. Instead of offering off-the-shelf products, we work closely with clients to develop customized drilling fluid programs based on specific formation, pressure, and environmental conditions.
Our clients benefit from:

• Real-time, data-driven decision-making
• Optimized wellbore stability and reduced nonproductive time (NPT)
• Solutions that reduce costs while improving well integrity and extending the production lifecycle

Fluid monitoring is a core component of every Baker Hughes fluid deployment. Our specialists measure and report critical parameters—such as temperature, density, chemistry, and rheology—multiple times a day. This includes tracking fluid losses, system volumes, pit levels, and overall performance metrics.

For operations requiring higher frequency or precision, such as drilling in narrow pressure windows, we offer the i-Trak™ Automated Fluids Monitoring (AFM) service. This system delivers continuous, real-time data on the drilling fluid’s density, rheology, and temperature as it enters the wellbore.

The i-Trak AFM integrates seamlessly with other i-Trak automation services to enhance hole cleaning, ROP, and pipe tripping efficiency. It can also support remote operations and multiskilling strategies to reduce the number of personnel on board.

Yes. Baker Hughes provides specialty drilling fluid additives specifically engineered to address complex drilling challenges such as tight pressure margins and extended-reach or horizontal wells.

Our portfolio includes:

• High-performance lubricants for water-based and oil-based drilling fluids that reduce torque and drag and improve ROP in high-angle and lateral wells
• CHEK-LOSS™ lost circulation materials to combat fluid losses and prevent differential sticking
• Pipe-freeing spotting fluids that avoid sidetracks and minimize downtime
• The BRIDGEFORM™ single-sack wellbore strengthening system that enhances wellbore integrity in structurally sensitive formations

Our Fluids Environmental Services (FES) provide comprehensive solutions for managing drilling waste in compliance with environmental regulations.

We offer:

• Solids control: Field-tested equipment, including shale shakers and centrifuges, easily deployed with a minimal rigsite footprint
• Cuttings processing: A full suite of bulk cuttings transfer, skip-and-ship, and cuttings dryers that reduce chemical use and environmental exposure
• Liquids processing: Systems for dewatering, filtration, and slop treatment that reduce the volume and impact of spent drilling mud
• Cuttings reinjection: Specialized equipment to safely dispose of drilled cuttings via subsurface injection, helping to minimize NPT and meet regulatory standards

Reservoir drill-in fluids are a specialized type of drilling fluid designed to be minimally damaging to the reservoir’s hydrocarbon-producing pay zone. While conventional fluids provide functions like well control and hole cleaning, reservoir drill-in fluids are customized to match specific reservoir conditions to minimize invasion, boost productivity, and prevent issues like clay swelling or scaling. 

Baker Hughes offers a range of drill-in fluids for multiple reservoir types and applications, including water-based and invert emulsion systems. Our proven systems offer simplified filter-cake removal and improved pay zone protection for maximum long-term production.
