Product Description

Product Description

FLEXSEAL^® lost circulation material (LCM) is a unique, precisely graded, inert, elastomeric sealant material. It is highly compressible and deformable, and has high tensile and shear strengths. These characteristics allow FLEXSEAL^® to perform effectively outside the limitations of common fibrous materials, as it will withstand higher differential pressures while bridging micro-fractures and sealing permeable sands. FLEXSEAL^® is used to control seepage loss in depleted formations, prevent differential sticking and cure lost circulation. FLEXSEAL^® is truly the next generation in fluid loss solutions. The product is available in fine and medium grades to cover a wide range of applications.

Applications/Functions

• Used in a preventive sweep application when known or anticipated loss/seepage zones are to be encountered
• Helps prevent differential sticking, seal micro-fractures and aids in preventing lost circulation
• Spotting as a pill for lost circulation

Advantages

• High shear and tensile strengths; Compressible and deformable
• Excellent sealing characteristics
• Environmentally safe, non-toxic, non-damaging to MWD tools

Typical Properties

• Appearance: Mixer of white and gray particles with black and tan granules and fibers
• Specific gravity: 1.8
• PSD of FLEXSEAL^® (Fine): D10-27μm, D50-92μm, D90-236μm
• PSD of FLEXSEAL^® (MED): D10-55μm, D50-712μm, D90-1385μm

Recommended Treatment

• Sweeps are mixed at 20 ppb FLEXSEAL^® (Fine) and 10 ppb FLEXSEAL^® (MED) and are typically 50 bbls

Package

• 25 LB SACK, 50 sacks per pallet
