Lost circulation material
M-I SEAL lost-circulation material [LCM] is an all-purpose additive designed to reduce severe lost circulation as well as minor seepage losses.
The product is effective when drilling highly porous matrix formations that are fractured or vugular. M-I SEAL material is a specialized blend of flake, granular, and fibrous materials, thus making it considerably more effective than using only single types of LCM. Its material composition allows it to be used in virtually all lost-circulation applications and loss-prevention situations without the need to combine or blend other LCMs. M-I SEAL lost-circulation material is available in fine, medium, and coarse blends.
|Typical Physical Properties|
|Physical appearance||Blend of flake, fibrous and granular particles|
|Fine particle size||20% retained on a 20-um mesh screen|
|Medium particle size||20% retained on a 12-um mesh screen|
|Coarse particle size||20% retained on a 8-um mesh screen|
M-I SEAL lost-circulation material has applications in both water-based and oil-based muds. For oil-based mud systems, large treatments with M-I SEAL material will require increased treatments with surfactants to prevent water-wetting of solids.
Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions as described in the safety data sheet.
M-I SEAL lost-circulation material is packaged in 50-lbm [22.7-kg] multi-wall paper sacks. Store in a dry location away from sources of heat or ignition, and minimize dust.
