Kati switches drilling rig to biofuel reducing GHG emissions by 50% or more

In Finland, Oy Kati Ab, a long-term drilling contractor of Keliber’s, has started to use biofuel in the drill rig at Keliber’s exploration site in Central Ostrobothnia. The measure will reduce the emissions caused by drilling by more than 50%. 

According to calculations made at Kati, the switch from regular fuel oil to biofuel makes it possible to reduce emissions by 50% or even more. It is estimated that during 2020 drilling at the Keliber work site generated emissions of 78.04 metric tons of CO2e, of which 95.2% was caused by fuel usage. If biofuel had been used, the estimated emissions would have been 37.90 t CO2e or 51% less. The emission reduction (40.14 t CO2e) is equivalent to 286,714.3 kilometers by car, which would take one 7.15 times around the globe. 

The price tag for biofuel is about 25% bigger than for fossil fuel, which means an increase of about 2% in the total drilling cost.
