How much CO2 does grinding barite for drilling mud emit per tonne?

Grinding to drilling grade fineness is most of it: mill electricity times 0.710 kg CO2 per kWh, divided by tonnes. Add mining diesel and freight to the buyer. Barite is not a CBAM good, but oilfield buyers increasingly ask for a figure.

Records

• Mill electricity by month.
• Mining and haulage diesel.
• Tonnes dispatched at the specified density grade.

Buyers

Oilfield service companies count your figure in their Scope 3 Category 1. Give it per tonne with the grade named.

What Senseible does here

Senseible reads the plant's electricity bills (CEA grid factor 0.710 kg CO2 per kWh, CO2 Baseline Database version 21.0) and fuel invoices (IPCC 2006 defaults) into a fingerprinted Scope 1 and 2 record, the plant-level input to a per-unit figure. Bought-in materials go to the supplier evidence trail; product reports are self-declared drafts.

• Stone crusher per tonne
• Dumper diesel per tonne
