KLA-SHIELD

Enhanced-polymer water-based drilling fluid system

Rig against sunset.
KLA-SHIELD system is ideal for high-angle wells in reactive shale formations where wellbore stability, torque and drag, and borehole and logging quality are major concerns.

Excellent shale inhibition and flexibility for a variety of drilling challenges

The KLA-SHIELD 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 system is fine-tuned to meet a variety of drilling challenges—large-diameter wellbores, extended-reach drilling, and highly reactive shales. It also is ideal for drilling high-angle wells in reactive shale formations where wellbore stability, torque and drag, and borehole and logging quality are major concerns.

The formula for superior clay inhibition

The KLA-SHIELD system uses three different mechanisms to inhibit swelling and dispersion of clay.

Flexibility for land and offshore

Products that make up the KLA-SHIELD system are formulated to address environmental concerns worldwide, both on land and offshore.

  • Onshore, the KLA-SHIELD system can be engineered to provide shale inhibition without the use of salts, and it contains no aromatic or cyclic hydrocarbon compounds, making cuttings ideally suited for land farming.
  • Offshore, the system displays relatively low marine toxicity, provides relatively fast biodegradation rates, and minimizes cuttings piles and benthic impacts.
