Excellent shale inhibition and flexibility for a variety of drilling challenges

The KLA-SHIELD™ enhanced-polymer water-based drilling fluid system includes a broad range of polyamines that make it a preferred system when environmental guidelines dictate a water-based drilling fluid and hole conditions demand flexibility. The KLA-SHIELD system is specifically designed to address a variety of drilling challenges, including large-diameter wellbores, extended-reach drilling, and highly reactive shales. It is particularly well-suited for drilling high-angle wells in reactive shale formations, where maintaining wellbore stability, managing torque and drag, and ensuring high borehole and logging quality are critical concerns.

The KLA-SHIELD system employs three mechanisms to prevent clay swelling and dispersion:

• KLA-STOP™ liquid polyamine shale additive effectively inhibits shale or gumbo clays from hydrating, reducing the risk of bit balling.
• IDCAP D™ polymeric shale inhibitor is a low-molecular-weight, dry acrylic acid copolymer that provides cuttings encapsulation and clay dispersion inhibition.
• ULTRAFREE NS™ water-based mud ROP enhancer is a unique blend of surfactants and lubricants. It coats drill cuttings and metal surfaces, such as the BHA and bit, to reduce the accretion tendency of hydrated solids with each other.

• Ensures reactive shale inhibition
• Meets environmental standards
• Provides flexible formulation and additives
• Maintains wellbore stability
• Enables better waste management

• Polyamine base for environmental performance
• Superior stabilization in fractured shales
• Easy to build and maintain
• Reduced clay dispersion and hydration
• Ability to drill in high-angle wells
