Gerke These costs resulted from non-productive time, remedial operations expenses and fluid-replacement costs and ranged from $120,000-$170,000 (USD) on individual wells. ADVANTAGES FL-17 can be used in casing and liner cementing using fresh to saturated salt-water cement slurries. Halad-766 fluid-loss additive is extensively used to retard foam slurries without reducing viscosity. Use of the Arx LCM package not only eliminated multi-stage cementing costs, but helped the operator avoid costs previously experienced due to loss of circulation events across the brown dolomite. In cementing operations, loss of the aqueous phase can severely affect the performance of the slurry and set cement. The material is nonretarding, thus making good compressive strength development possible at low temperatures.
