The Well Logging and Perforation Division conducts “on-line” logging of cased production and gas and liquid storage wells. Selected measurement methods and their careful combination and specification provide valuable information that allows the operator to accurately assess the well or reservoir parameters in terms of both production and injection capacity.

Additional logging methods are designed to facilitate testing of cased and completed wellbores, underground gas storage wells in particular.

Well logging offers an optimal solution to deal with a range of issues that may arise during the operation of oil and gas wells and facilitates geological surveys as well as periodic inspections of injection-withdrawal wells at gas storage facilities.
