Does anyone have any thoughts on the use of a Reservoir Isolation Device being used as a barrier during the running of an upper completion in which the primary hydraulic barrier is underbalanced as part of that operation. In this case the RID is a design which can be opened by presure cycling and therefore could theoretically be opened via swab/surge dependent on mumber of cycles left on the tool.
