Dutch twill weave sand control screen — 92% flow retention after 12 months. Unlike conventional wire-wrapped screens that progressively plug, Jingtao’s anti-clogging screen uses precision Dutch twill weave geometry to maintain permeability under high fines loading.
In a 1,200m horizontal Bohai Bay well producing 14° API heavy oil with high sand cut, the screen retained 92% of its initial flow capacity after 12 months — versus conventional screens that drop below 40% within 6 months.
