Case Study: Wellbore Clean Up - North Sea
/An offshore service company used SAS WellboreClean 116SC for a casing cleaning project in the North Sea. In doing so, the service team was able to reduce the cleaning times by 60% and reduce the chemical train by 70%.
The Problem...
The service company needed the SAS product to complete a drilling well so that it could be handed back over to production in minimal time with minimal waste production. Therefore, the key project outcomes were:
To reduce downtime and bring forward well production
To reduce the volume of waste produced from well completion
The SAS Solution...
Using SAS WellboreClean 116SC not only were the team able to hand back the well in record time, they also significantly reduced the waste, compared to standard detergents/solvents.
Afterwards a brine completion string was run and the well was completed and handed over to production. SAS WellboreClean 116SC successfully eliminated the need to use additional detergents, solvents, high viscous spacers or carry out multiple flushes with seawater and brine.
To Sum Up...
The total reduction in waste volume produced from the job using the SAS product was over 92%. SAS WellboreClean 116SC was successful in enabling the simple treatment of waste both on and offshore.
As can be seen in the picture on the right, the solids were able to be recovered for disposal, the water was safe for disposal to sea and the base oil was recovered for re-use.
