TP- CALCIUM CARBONATE is an acid – soluble
weighting and bridging agent for drilling and workover /completion fluids.
TP- CALCIUM CARBONATE can be supplied in a
variety of grades to provide bridging or weighting particles of completion or
workover fluids. It can be also used as non-damaging loss circulation or
bridging material in oil muds to prevent differential sticking or muds losses
when drilling into the reservoir. The material is acid soluble so that good
clean-up is obtained by acidization.
The recommended treatment is 29 to 72 kg/m3
(10 to 25 lb/bbl) as a bridging agent for most application. Special pills or
port use 114 kg/m3 (40lb/bbl) more for controlling losses.
