Losseal Max HT

Losseal Max HT™ lost circulation control treatment mitigates severe to total losses by sealing fractures up to 0.4 in [10 mm] in a high-temperature environment. The Losseal Max HT treatment solids and fibers are delivered in a reservoir-friendly pill designed for easy mixing and preparation to reduce downtime at the wellsite.

• Lost circulation situations with moderate, severe, or total losses
• Natural or induced fractures
• Land and offshore drilling and cementing
• Losses in reservoir section
• High-temperature formations

• Cures losses without the use of cement plugs
• Reduces flat time during drilling operations
• Saves costs by reducing volume of lost drilling fluid and cement
• Reduces environmental footprint of the well construction by reducing the volume of lost drilling fluid to the formation
• Strengthens formation in advance of cementing
• Minimizes impact to well production and surface equipment

• Up to 90% acid soluble in 15% hydrochloric acid
• Pumpable through bypass sub on drilling bottomhole assembly
• Blend of particulates and reinforcing fibers
• Delivered as a kit for batch mixing in combination with the carrier fluid to ensure correct ratio of components

Losseal Max HT lost circulation control treatment is developed for high-temperature sections with moderate, severe, or total circulation losses. An engineered combination of fibers creates a network to bridge gaps, and a high concentration of solids work to plug the network of fibers, to enable the Losseal Max HT treatment to seal fractures up to 0.4 in [10 mm] wide. Optimized solid particle selection and size distribution result in rapid delivery of the solids for maximized plugging efficiency. Losseal Max HT treatment can be used on land or offshore rigs and can be pumped through open-ended drill pipe or through a bypass sub on the bottomhole assembly, to eliminate trip time and reduce nonproductive time. Because the Losseal Max HT treatment is highly acid soluble, it minimizes damage to the formation and impact to surface production equipment.
