Deformable & Composite LCM
Elastic Lost Circulation Material
An elastic lost circulation material based on modified high-polymer elastomers. It swells on contact with fluid and rebounds elastically to seal fractures, pores and loss channels with high pressure-bearing capacity, and is compatible with both water-based and oil-based muds.
APPLICATIONS
Application scenarios
- 01Micro-fractures and small-to-medium fissures in shale, sandstone and limestone
- 02Preventive, while-drilling and remedial lost-circulation treatments
- 03Freshwater, saltwater, saturated saltwater and oil-based mud systems
