LCM GT-N

GT-N is a high-performance Lost Circulation Material (LCM) engineered for direct addition to water-based or invert emulsion drilling and completion fluids for effective fluid loss control. Formulated from a proprietary blend of specialized flake, granular, and fibrous materials with meticulously controlled size distribution, GT-N offers significantly higher sealing efficiency than single-component LCMs.

Designed for seamless operational integration, GT-N has a minimal footprint on base fluid properties. It can be mixed directly into the active mud system or used in conjunction with other LCM pill treatments.

GT-N has three kinds of specifications: GT-N (F) for GT-N fine LCM, GT-N (M) for GT-N medicum LCM, and GT-N (C) for GT-N coarse LCM.

Properties

Features and Benefits

▲ Optimized Standalone Solution: Engineered with a multi-modal range of particle sizes and shapes to effectively seal losses without requiring additional LCM blending.

▲ Chemical Inert: Integrates seamlessly into water-based or invert systems with negligible impact on mud rheology and performance.

▲ Simplified Deployment: Requires no specialized mixing equipment, allowing for straightforward handling and rapid additions directly on location.

Applications

Seepage losses can be treated by maintaining a concentration of 2 to 12 ppb of GT-N (F) in the active system. For partial to total losses, it is recommended to spot a high-concentration pill containing 30 to 80 ppb of an optimized blend of GT-N (F), GT-N (M), and GT-N (C).

LCM GT-S

GT-S is a premium, acid soluble Lost Circulation Material (LCM) engineered for direct addition to drilling or completion fluids for superior fluid loss control.

Usage  Recommendation

Neotor^® NTS-M High Pressure Resistant LCM

Neotor^® is an engineered lost circulation material dominated by high-strength, flake-shaped particles manufactured via a specialized proprietary process. Composed of thermally stable, chemically inert materials, it is specifically designed for extreme high-temperature, high-pressure (HTHP) conditions. Under applied differential pressure, the optimized particle size distribution allows granular elements to bridge deeply within the fracture network, mechanically interlocking to increase near-wellbore stress. This initial framework enables multi-shaped particulates to subsequently fill and compact, forming an ultra-tight, low-permeability seal that enhances the local fracture gradient.

Properties

Benefits

▲ Superior Fractures & Cave Sealing: Delivers a high success rate in plugging natural fractures, induced fractures, and irregular small caves, particularly under harsh HTHP (high-pressure, high-temperature) conditions.

▲ High Pressure-Bearing Capacity: Forms exceptionally stable, robust plugs that resist high differential pressures far better than conventional LCMs, preventing secondary fracturing.

▲ Seamless Rig Integration: Completely non-contaminating to active drilling fluid systems and mixes easily through standard rig hoppers without requiring specialized equipment.

Neotor^® NTS-S Acid-Soluble LCM

Neotor^® NTS-S Acid-Soluble LCM is a premium lost circulation materials engineered utilizing specialized manufacturing technique that yields an acid-solubility rating exceeding 98%. Specifically designed for reservoir protection, this high-purity composition creates a temporary, high-strength seal over loss zones that can later be completely dissolved during standard acid clean-up operations.

Properties

Benefits:

▲ 98%⁺ Acid Solubility: Ensures near-total dissolution during clean-up, making it ideal for protecting sensitive pay zones without permanent formation damage.

▲ Effective Fracture Brdiging: Flake-shaped particles easily wedge into small caves, natural fractures, and induced fractures to establish a stable, non-flow-back bridge.

▲ High-Pressure Resistant Seal: Forms a robust plug capable of resisting high differential pressures, which helps prevent secondary formation fracturing.

▲ Excellent Structural Integrity: Completely water-insoluble; particles will not soften or deform under downhole conditions.

MudPlug LCM

Mudplug is a water-soluble, temperature-activated cross-linking polymer system formulated with a high concentration of low-molecular-weight anionic polymers. When integrated with traditional Lost Circulation Materials (LCM), the system undergoes a synergistic chemical reaction to form a robust, rubber-like ringing gel matrix. To optimize placement across varying geothermal gradients, the cross-linking kinetics can be precisely tailored to specific field conditions by adjusting the concentrations of the cross-linker and retarder agents.
