permeability reduction by bacteria plugging

[hermes76]

Hi guys,

Please, help me giving some directions about next:

* Is there any way to determine suitable concentration or number of bacteria at reservoir in order to avoid microbial formation damage?

* Is there any company or lab that works with bacteria cultures in cores?

* Is there any guide to determine acceptable bacteria limit for reservoir conditions (pressure, temperature, residual oil, oil properties, permeability, pore throat size,…) and/or injection water quality?

Any help would be highly appreciated.
