Case History X-PrimaTM Squeeze Cures Persistent Losses While Drilling Surface Interval Challenge Eliminate extreme losses while drilling surface interval Solution Newpark’s proprietary X-Prima high fluid loss squeeze Results Severe losses successfully mitigated Algeria While drilling in an unconsolidated calcareous formation in Algeria, a total loss of returns was experienced at 584 ft (178 m). Remediation including cement plugs were tried five times, but attempts to circulate fails. Fluid loss rates ranged from 50 to 75 bbl/hr (2.2 to 3.3 L/s) on each occasion. The decision was made to spot X-Prima slurry in the open hole to control these persistent, unsustainable losses. A 220- bbl (35 m 3 ) slurry with 105 lbm/bbl (300 kg/m 3 ) X-Prima lost circulation mat
