• Oils in submersible pumps

– Renolin CLP 32

– Discharge 20 ml /h

– 0,01 mg/l to sea

– Valemon discharge permit: 200 kg/yr

– Johan Sverdrup, 940 kg/yr

• New technology, pumps with dual seals

– No discharge

– Expensive retrofit

• Yellow oils possible available if pilot is successful

➢ Vanninjeksjon på Gullfaks gir økt H2S i reservoaret

➢ Årlige produksjonstap på 20 MNOK

➢ Mål: å redusere H2S -mengde til 2,5 ppm i eksport

➢ Optimalisere doseringspunkt, dysetype og detektorer

➢ Resultat:

➢ optimal utnytting av kjemikaliene

➢ optimal produksjon

➢ mindre kjemikaliebruk (fra 473 m3 til 245 m3 pr år)

➢ mindre korrosjon, mindre scale, bedre vann

➢ lavere EIF (Environmental Impact Factor)

➢ potensiale for reduksjon på hele sokkelen

(500 l/time, 60-70 MNOK/år)

➢ skal inn i neste utgave av NORSOK
