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. Veritrol 343. 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. The transition of the cement slurry from a liquid to a solid phase causes the hydrostatic pressure to drop and can allow gas to percolate through … Cement fluid loss must be controlled to obtain the right rheological properties for placing the cement and to ensure a good cement bond to pipe and formation. It can be used in wells with bottomhole circulating temperatures (BHCTs) of 180°F (82°C) and below. Microgel particles rapidly plug the pores within the cement, causing rapid formation of a thin, impermeable filtercake.
