Drilling Barite heavyweight additive is a barium sulfate material used to weight drilling mud
and cement slurries. Typically, 85 to 90% of barite additive will pass through a 325-mesh
sieve. Barite additive is effective at bottomhole temperatures (BHTs) between 80°F and 500°F
(27°C and 260°C). A barite additive concentration of 135 lb/sk of cement will provide a maximum
slurry weight of 19 lb/gal. Barite additive provide the following benefits: By increasing slurry
density, it helps restrain high formation pressures and improve mud displacement. It
is applicable
in deep, high-temperature wells.
According to The Barytes Association almost 70% of global barite consumption is used as
a weighting agent in oil and gas well drilling.
The oilfield market, which consumes a range of industrial minerals in vital applications, was
severely impacted in 2020 by the pandemic with travel restrictions significantly reducing demand
for transport fuels. As a result, producers
and traders of barite, the largest volume mineral
consumed, saw sales plummet by up to 90% on the previous year.
The European barite market, 50% of which is accounted for by industrial market applications
(eg.
chemicals, fillers), was somewhat protected from the oilfield downturn (and was even helped
a little with increased paint sales owing to home renovation during lockdown), but in the USA
more than 90% of barite consumed
is for oilfield drilling, so this market was hard hit.
