Paper Number: ISOPE-I-20-2185
.... A comb-type polycarboxylate dispersant was applied to the high-density (2.28g cm −3 ) slurry and this was used for a 244.5 mm salt paste layer casing at 55–58 °Cambient temperature for 5 wells in Halfaya and Missan Oilfeild in Iraq. More than 85 % of the cementing job was excellent. INTRODUCTION...

.... Abstract Field results indicate that displacing cement in turbulent flow during the primary cementing operation has materially reduced remedial cementing. Lower displacement rates with subsequently reduced frictional pressures have been achieved by using dispersants or thinners in the cement slurry...

Influence of slurrry dispersion state Similarly to the fact that adhesion strength is sensitive to steel surfaces, one could think that it also depends on slurry dispersion state, and therefore cement aggregate size during cement placement. To study this effect, we varied cement...
