The main focus is on the best possible preservation of reservoir properties in the course of the above operations as well as technologically competent modelling of the formulation and technology selection processes and well productivity related servicing.


Killing fluids play a very important role in well maintenance and workover operations. The proper selection of kill fluids may prevent such hazards as fluid loss, oil and gas shows, production loss after workover, and aggressive corrosion effects on drill string and bottom-hole equipment. 


AKROS has designed a wide specter of technologies and services with reduced impact from well-killing operations aimed to the improvement of work quality, reduction of well intervention periods, and mitigation of related risks.
