... spending of the acid on a stoichiometric basis. The potential for CaCO 3 scaling at Heidrun is not particularly high, but implementing an integrated approach one could not exclude it as an additional damage mechanism in the near well bore area. Additional calculation in a scale modeling code proves...

... lb/gal density range. The total amount of the sized CaCO 3 bridging particles is kept relatively low, 13 to 35 lb/bbl, so that thin, chemically removable filter cakes are produced. The size distribution of these bridging particles is designed according to the ideal packing sequence for optimizing...

... emulsion mud system, with CaCO 3 and barite as bridging agents, would effectively reduce the amount of filtrate lost to the formation and hence reduce the damage caused during drilling. Paramount to the effectiveness of the mud system is the distribution of the solid bridging agents required through...
