Capillary & Spooling

Flowco’s capillary chemical systems protect your well, boost production, and reduce costly downtime with no shut-ins or guesswork.

What is a Capillary Chemical System?

Capillary chemical injection systems are precision-engineered to deliver treatment fluids directly to targeted zones within oil and gas wells. Designed to prevent scale, corrosion, salt buildup, and paraffin, these systems reduce interventions, extend equipment life, and improve overall production performance.
