DRILAMINE® (cost-effective polyamine shale inhibitor)

DRILAMINE® is a cost-effective industry grade polyamine shale inhibitor. It acts by neutralizing negatively charged surfaces of clay particles and prevents hydration by forming a hydrophobic layer on cuttings and wellbore wall.

Description

DRILAMINE® particles dissolved in the drilling fluid filtrate penetrate and adsorb into the pores and microfractures, narrowing the pore space by the mechanism of electrostatic interaction.

Applications/Functions

• Used as one of the main components of high-performance water-based muds
• Suppresses clay interlayer hydration, prevents swelling
• Adds lubricity
• Prevents pore pressure transmission

Advantages

• Cost-effective
• Unlike KCl does not dry out shales, prevents compaction and spalling
• Can be used in reservoir drill-in fluids

Recommended treatment

2-10 ppb (5,6-28 kg/m3). If added directly to the active mud system it is recommended to add calculated DRILAMINE® amount throughout 2 full circulation cycles.

Typical properties

Appearance – Brown liquid

Handling
