Three reservoir sections have been drilled and completed using cesium/potassium formate brine in the Kvitebjørn field since 2007. The reservoir section was drilled using MPD technology with a specially designed drilling fluid.

Nine reservoir sections were drilled and seven completed with cesium/potassium formate brine in the North Sea’s Kvitebjørn field from 2004 to 2007.

Cesium formate brine has provided effective well control in over 20 HPHT workover and suspension operations in the Elgin / Franklin fields in the North Sea.

TXM successfully used high-density cesium formate brine as well control fluid during the appraisal of a extreme HPHT basin-centred gas accumulation in Hungary. The well was later suspended three times with cesium formate. The longest suspension period lasted about six months.

Deploying 2.19 s.g. / 18.28 ppg cesium formate brine in HPHT perforating operations brings significant HSE benefits and delivers productive wells with low mechanical skins. 

Six reservoir sections were drilled and completed with cesium / potassium formate brine in the HPHT Huldra field in the North Sea.
