Amine Base Shale Inhibitor

Brief Introduction:

As a shale inhibitor, it can maintain hole stability, can effectively protect hydrocarbon reservoirs and prevent brittle shale from peeling off the wall.

Description

As a kind of low molecular mass polyamines, , the reaction of DFSC-07 polyamines Shale Inhibitor with clay minerals can involve several  mechanisms  including  hydrogen  bonding,  dipole interactions and ion exchange. DFSC-07 can be compatible with drilling fluids and increase solid tolerance since the product itself is electrically neutral. It is non-toxic, non-fluorescent, and meets the requirements of environment and well-logging, DFSC-07 can also be used in saltwater mud and deep well and ultra deep wells.

 

Usage and dosage

As a shale inhibitor, DFSC-07 can maintain hole stability, can effectively protect hydrocarbon reservoirs and prevent brittle shale from peeling off the wall. The recommended treatment concentration is usually 1 % - 2%.

 

Package and storage

The product is usually kept in a plastic drum. Net weight is 180 kg/drum. Special packages are available based on customers' requirements.
