Hi everyone,
I have a question related to Acid treatment in Sandstone.
We fracture the Low permeability sand reservoir and later treated it with 15% HCl and 2% KCl based on past job success.
But while treating the reservoir with Acid Workover rig had some malfunction and it took them long time to fixed the problem (about two days). So, during this whole time acid stay remain in the formation.
Once, we start flow back well pressure was high but later well pressure falls dramatically.
Any suggestions,
How we can clean reservoir to bring the reservoir pressure back ???
