• 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
